Nowadays, making purchases with a credit or debit card in physical stores and online is an essential activity for acquiring everyday goods.
Security in these operations is essential. For this, these payment methods use the CVV or CVC code, which means Card Verification Value or Card Verification Code respectively, and its purpose is to verify that the cardholder has the physical card and to protect online and phone purchases.
Below, we will explain in detail what the CVV is, where to find it, the types of security codes, and tips to keep your cards secure.
If you are going to make purchases online or by phone, you will need to provide the security code of your debit or credit card to verify it belongs to you.
In most cases, the CVV is located on the back of the card and consists of 3 or 4 numbers.
Here is a quick guide to locating the verification code depending on the card type.
Card type
Where to find the CVV?
How many digits does it have?
Visa
Usually on the back, next to the magnetic stripe.
3
Mastercard
Usually on the back, next to the signature.
3
Discover
Usually on the back, to the right of the signature.
3
American Express
Usually on the front, next to the card number.

One way to strengthen security during electronic transactions is the use of a dynamic CVV, which is found in digital applications or cards and is valid only for a limited time to make a single purchase. This reduces the risk of misuse of your personal data if it is exposed.
The CVV number is a security lock that allows you to use your physical and digital cards with confidence that a third party cannot access your money.
These are the most important functions of this security code.
It is especially useful for protecting electronic operations by verifying that the cardholder is the one making the purchase.
When making an online purchase, you must enter the card’s CVV to validate the transaction. This process is more secure when using a dynamic CVV because it reduces the risk in case of fraud.
Unlike other data usually included on physical cards, such as the number and expiration date, the CVV is not stored in online store systems, so your data remains safe in case of potential identity theft.
The purpose of the CVV is to provide you with security and peace of mind when making online purchases.
You may notice different types of CVV since the name can vary depending on the card issuer.
These are the security codes most commonly used by financial institutions to protect users’ cards.
The CVV (Card Verification Value) is the security code created for Visa cards. It consists of 3 or 4 digits and is used to confirm that the person making the purchase actually has the card.
The CVC (Card Verification Code) is the version of the CVV used by Mastercard cards. It has the same function and a similar composition.
The CVV2 (Card Verification Value 2) is a digital version of the CVV used to provide greater protection in online purchases. While the traditional CVV is used during payments at card terminals, the CVV2 is requested to confirm remote transactions.
Some people avoid or minimize the use of physical or digital cards due to fear of having their personal data stolen and generating unauthorized charges. However, financial institutions and digital platforms currently offer the necessary security measures to protect your assets.
Thanks to the implementation of codes such as the CVV, the risk of experiencing a security incident is minimal and decreases even more when you have the right information to apply practical strategies like the following.
Bank cards are useful tools that require responsible and cautious use. Learning to use your card safely and confidently is also part of building financial stability.
This time we explained what the CVV or CVC is, why it is important, and gave you some tips to keep your checking accounts secure.
The security provided by the CVV is the same you need in all your financial operations, such as digital payments, cash deposits, and international money transfers. For this, you have Comun, the digital platform specially designed for immigrants living in the United States who want to manage their money safely and without complications, with clear and competitive fees.
Comun is the financial platform that truly understands your needs and offers fair, tailored solutions.
Open your Comun account and start managing your money in the United States with confidence. Send, receive, and monitor your expenses from the mobile app.
If you still have questions, check the following section.
It is not advisable to give your CVV to someone else, as they could make purchases not authorized by you. Make sure to protect your banking information so only you have access to it.
No, the card number consists of 16 digits and identifies the checking account. The CVV consists of 3 or 4 digits and verifies that the holder is the card owner.
In physical stores, it is not strictly necessary, as the purchase is validated with the chip and PIN. For online purchases, it is essential to enter the CVV to authorize the transaction.
Conclusion
Starting a business as an immigrant is entirely possible with the right steps. By choosing the right business structure, obtaining the necessary tax IDs, and registering properly, you’ll build a strong foundation for success.

Checking account

Need a safe, simple way to manage your money? It’s important to understand the different bank account types offered by U.S. financial institutions and digital platforms.
Two primary examples are savings accounts and checking accounts. While common in the U.S., they differ in important ways especially relevant when you’re new to managing money in a new country.
It’s easy to assume both accounts do the same thing. Below, we detail what each account is, the main differences, comparisons, and examples.
A checking account is one of the most popular financial products. It’s designed for frequent transactions: receiving pay, sending transfers, and paying at physical and online merchants.
These are the main benefits of opening a checking account:
What is a checking account used for?
A checking account has multiple functions, for example:
In short, this account type covers everyday needs with simple, accessible tools.
Here’s where you can learn about different checking account types and their features.
Unlike checking, a savings account is for setting money aside longer term and growing it through interest.
Advantages of a savings account:
Though different, both accounts complement each other to cover short-, mid-, and long-term financial needs.
These are the main differences between them.
Learn about joint bank accounts, an excellent way to manage finances as a team.
As you can see, the decision to open a checking or savings account depends on your needs. However, combining both is a strategic decision for financial management. On the one hand, a checking account allows you to keep up with daily payments, while a savings account is designed to plan for the future and keep your money separate.
In this article, you learned the difference between checking (for daily transactions) and savings (for growing money over time to meet future goals).
Immigrants arriving in the U.S. need bank accounts that offer security and trust, yet often face hurdles due to strict requirements that disadvantage many in the community.
Meet Común, the checking account that understands immigrants’ needs!
Here are some benefits that await you:
Open your Común account today and organize your money in the U.S.
If you still have questions, check out our FAQ section.
It depends on your needs. If you're looking for an account for everyday transactions, such as transfers and deposits, receiving paychecks, and making utility payments, a checking account may be an option. If you want to save your money for the long term, consider a savings account.
Yes, you can separate your goals and organize your money. Use a checking account that supports domestic and international transfers with clear, affordable fees, and keep a savings account to plan long-term.

Did you know it is possible to send money without having a bank account? The lack of access to financial services is a problem that negatively affects the quality of life of thousands of immigrant workers in the United States.
For example, according to a recent survey, the rate of the Latino community in the United States without a bank account dropped from 15% to 10% over the last two years. However, it remains high compared to the national average of 4.5%.
While having a bank account facilitates financial transactions such as transfers, in-store payments, and online purchases, there are now alternatives that allow you to access banking services without needing an account.
Below, you will discover how to transfer money from one card to another without an app or bank account, as well as the safest and simplest methods available to you.
Not having a U.S. bank account is not an obstacle to sending money domestically or internationally, as there are methods widely used among immigrant workers who regularly send remittances and conduct other transactions using prepaid cards and cash payments.
This is one of the most popular ways to send money without a bank account due to the accessibility, variety of payment methods, and broad coverage typically offered.
International money transfer providers are companies that specialize in facilitating money transfers from one country to another. The key features of these services include:
Comun allows you to send money to your loved ones for a modest transfer fee starting at USD 2.99 up to the applicable limits. It is very simple; just follow these steps:
1. Open your account with Comun; it will only take a few minutes!
2. Choose the most convenient delivery method for your recipient, such as cash pick up at a physical store like Oxxo, Grupo Elektra, 7 Eleven, and more.
3. You may also send money directly to a bank and have it picked up at one of its branches.
4. Track the delivery directly in your Comun mobile application.
Comun is an excellent option for our community, as it provides Spanish-language service, which is highly appreciated by the immigrant community. Open your account today and start sending money without complications.
To send money without a bank account, you only need the following information about your recipient:
P2P (peer-to-peer or person-to-person) services allow immediate money transfers between individuals without intermediaries. These options are useful for everyday needs such as paying rent, shared services, splitting transportation costs, and sending money to your relatives in the US or internationally.
Other alternatives involve sending a cashier’s check, a certified check, or a money order through the postal service.
This type of check is issued with the bank’s funds. The customer must pay in cash or directly from their account, and the check is made payable to the recipient.
This check is issued using the customer’s funds. The issuer must have a bank account so that the bank can verify the availability of funds. The recipient may cash the check directly at a bank branch.
Another way to send money without a bank account is by using a money order, which is a type of prepaid payment order. To do so, you will need to:
1. Go to a post office or authorized retailer, such as USPS or Walmart, to purchase a money order.
2. Write the beneficiary’s name in the “pay to the order of” section.
3. Write your name in the “purchaser” section.
4. Sign in the space designated for the purchaser, generally on the front of the document.
5. Keep the receipt with the serial number.
6. Pay the amount to be sent plus applicable service fee.
7. Send the money order via regular or certified mail.
8. Write the recipient’s address in the center of the envelope and the sender’s address in the upper left corner.
9. Purchase a postage stamp at the post office and attach it to the envelope.
10. Drop off the envelope at the post office.
The recipient may cash the money order at an authorized branch upon presenting valid personal identification.
The downside of this alternative is that it takes longer to arrive, as it relies on a traditional mailing method.
There are other options available to send money without a bank account, such as prepaid cards and mobile applications.
Reloadable prepaid cards function similarly to debit cards, with the main difference being that they are not linked to a bank account. They also allow you to pay for services and make online purchases.
To send money using a prepaid card, you only need to:
1. Identify an international money transfer service that supports prepaid cards, such as Western Union or MoneyGram.
2. Select your preferred provider and choose the prepaid card option on their website.
3. Enter the recipient’s information, making sure it is compatible with the selected platform.
4. Confirm the transfer and pay the amount plus the applicable service fee.
Done! The recipient will receive the money on the prepaid card as if it were a bank transfer.
Lastly, you may opt for mobile wallets or applications that offer money transfer capabilities. Some examples include Cash App, Venmo, and Remitly, which provide access to an mobile app you can use to send and receive money.
These applications do not require a bank account and are user-friendly. Some also offer physical cards that function similarly to debit cards.
Ensure that the recipient’s information, such as name, account number, or phone number, is entered correctly. Any discrepancies could prevent the recipient from collecting the funds.
Each provider has its own rates depending on the receiving country, amount, and exchange rate. Remember, with Comun you do not pay excessive fees, and you ensure your family receives more for less.
Some platforms have sending limits that should be considered before selecting a service. For instance, Western Union has a daily limit of USD 7,499, while Cash App allows up to USD 7,500 per week for verified accounts.
Even though these methods are secure, it is important to keep receipts and reference numbers in case a clarification or issue arises.
It is essential to ensure that you use a trusted service. Check online reviews and verify that the provider has an official website and/or physical offices.
Unfortunately, scams are common around financial services. No legitimate institution will request passwords or verification data. Always access official websites. If in doubt, visit an authorized branch.
Most options allow you to complete transfers in minutes, but some may take several days. Consider this before choosing your preferred service.
Absolutely. Comun is backed by leading financial institutions to protect your funds up to the applicable limits. Additionally, you can track your transfer directly through the Comun mobile app.
Comun offers a transfer fee starting at USD 2.99, regardless of the amount you send up to the applicable limits. Your first transfer is commission-free!
Cash is typically available within approximately 1 hour at the selected store or bank branch.
You need the full name of your recipient, and they must present official identification.

A medida que las razones para transferir dinero internacionalmente aumentan, también lo hacen los métodos por los cuales se pueden completar estas transacciones. Este artículo te guiará en la selección del servicio adecuado para tus necesidades, proporcionará un recorrido detallado del proceso de transferencia de dinero internacional y ofrecerá consejos para minimizar las tarifas y navegar por el paisaje regulatorio de las transferencias de dinero internacionales. Ya seas un remitente por primera vez o busques optimizar tus transacciones regulares, las siguientes perspectivas te equiparán con el conocimiento para tomar decisiones informadas.
En un mundo cada vez más globalizado, la capacidad de transferir dinero a través de fronteras es esencial para propósitos personales y comerciales por igual. Las transferencias de dinero internacionales facilitan el flujo de fondos entre diferentes países, sirviendo una variedad de necesidades: desde apoyar a miembros de la familia en el extranjero, hasta pagar por servicios en otro país, hasta invertir en activos en el extranjero.
Tradicionalmente, los bancos han sido las principales instituciones que manejan estas transferencias, ofreciendo seguridad y fiabilidad. Sin embargo, a menudo son criticados por tarifas más altas y tipos de cambio menos favorables. En respuesta a estas limitaciones, han surgido una variedad de servicios alternativos de transferencia. Los servicios de transferencia en línea ofrecen tarifas y tipos de cambio competitivos, junto con plataformas fáciles de usar que simplifican el proceso, haciendo que las transacciones internacionales sean accesibles para todos con acceso a internet. Además, las aplicaciones móviles han revolucionado el escenario de transferencia internacional, permitiendo transferencias instantáneas con solo unos pocos toques en un smartphone. Cada una de estas entidades tiene su propio conjunto de ventajas y es adecuada para diferentes tipos de clientes y necesidades.
Al decidir sobre un servicio para transferencias de dinero internacionales, varios factores clave deben guiar tu elección. Las tarifas de transferencia son a menudo la primera consideración; estas pueden variar significativamente entre servicios, con algunos cobrando una tarifa fija, otros un porcentaje del monto transferido, y otros ofreciendo transferencias sin tarifas en ciertos umbrales. Los tipos de cambio proporcionados por el servicio son igual de cruciales, ya que incluso una pequeña diferencia en el tipo de cambio puede afectar significativamente la cantidad que recibe el destinatario, especialmente en transferencias más grandes.
La velocidad de entrega es otro factor importante. Dependiendo de la urgencia de tu transferencia, puedes elegir un servicio que ofrezca transferencias instantáneas o del mismo día, incluso si podría costar un poco más. Además, no todos los servicios operan en cada país; por lo tanto, la disponibilidad del servicio en el país de destino es una verificación vital.Por último, no se deben pasar por alto las preocupaciones de seguridad y la disponibilidad del servicio al cliente. Asegúrate de que el servicio tenga medidas de seguridad robustas y ofrezca un soporte al cliente confiable en caso de problemas. Los proveedores deben estar regulados por las autoridades financieras relevantes, y deberías tener acceso al servicio al cliente a través de múltiples canales (teléfono, correo electrónico, chat) en cualquier momento.
Enviar dinero internacionalmente involucra algunos pasos clave. Aquí te mostramos cómo puedes hacerlo:
Por seguridad, siempre verifica dos veces los detalles del destinatario y los resúmenes de transacciones antes de confirmar la transferencia, y solo utiliza redes seguras cuando realices transacciones en línea.

Asegurarse de que todas las partes tengan expectativas claras sobre el tiempo y el uso de los fondos puede ayudar a prevenir malentendidos. Además, los remitentes deben estar conscientes de las posibles barreras lingüísticas o desafíos burocráticos que podrían complicar el proceso de la transacción. Por ejemplo, en algunos países, los destinatarios podrían necesitar proporcionar documentación extensa para recibir fondos, o podría haber restricciones gubernamentales sobre las transferencias bancarias entrantes. Al estar consciente de estos factores, los remitentes pueden prepararse mejor a sí mismos y a sus destinatarios para una transferencia exitosa, minimizando retrasos y maximizando el impacto de los fondos enviados.

Being far from family and friends is one of the main challenges faced by immigrants living in the United States. Fortunately, sending mail is a way to maintain the bond with loved ones across borders.
In the United States there are several options for sending packages to Mexico. Below we explain the features of each service so you can choose the one that best fits your budget and needs.
There are two shipping options from the United States to Mexico: through USPS or private courier companies.
These are the main United States Postal Service (USPS) shipping services and their characteristics. Please refer to their website for the most up-to-date information.
There are also private courier company alternatives that offer excellent service and additional shipping options. Please refer to each courier’s website for most up-to-date information.

As seen in the previous section, it is impossible to precisely estimate the shipping cost and time for each courier service from the U.S. to Mexico. Several factors influence the final result, explained below.
This is the main factor that affects the final cost of an international shipment — the heavier and bulkier the package, the higher the rate. Also check whether the company has a maximum shipping weight.
The final destination also matters. Sending a package to Mexico City is usually cheaper than to a rural area.
Express or priority shipping services are faster and therefore more expensive.
If you ship during Christmas, New Year or high-demand dates, expect possible delays or extra costs.
Before going to your preferred shipping carrier’s office, make sure all information is ready to avoid delays and ensure your package reaches your loved ones without issues.
Make sure your package does not contain restricted items for entry into Mexico, such as perishable food, flammable liquids or counterfeit goods. If unsure, check customs rules.
Use a proper box or purchase one at the post office. If the contents are fragile, protect them well and place the label correctly when closing the box.
Double-check as many times as needed that recipient details (name, ZIP code, neighborhood) are accurate. Even small errors can send a package to the wrong place.
Finally, keep the tracking number and receipt; they let you track the package and clarify any issues if needed.
We understand how important it is for immigrants to send packages to Mexico from the United States. More than a packaged product, it represents birthday gifts, greetings from afar, and fulfilled dreams for the people you love most.
That’s why it’s important to follow these tips when sending a package to Mexico.
Sending packages to your loved ones in Mexico is a way to show them they’re still important to you. That’s why planning your shipments—and your finances—is essential.
Get to know Común, the digital platform that helps immigrants manage their money in the most accessible way, as you can open an account using a qualifying official identification from your home country.
Just as your packages travel with care, Común supports your financial well-being.
Open your account with Común and stay connected with your loved ones through remittances.
If you still have questions, check the following section.
It depends on the courier company, but in general, an express service takes 3 to 5 business days.
When you send your package, you’ll receive a tracking number so you can follow it until it reaches its destination. Some courier options only provide tracking until it leaves the United States.
The USPS First-Class Package International Service is ideal for economical shipments, though the delivery time is usually longer.

Some plans cover only basic services, while others offer comprehensive coverage including hospitalization, specialist visits, and prescription drugs. Review your medical needs (and your family’s) to gauge the right level.
You must understand both before enrolling. The deductible is what you pay out of pocket before your plan starts paying; the copay is the fixed amount you pay each time you use a covered service.
Check that the plan includes a robust network of hospitals and clinics near your home or work, so you can access care when needed.
As an immigrant in the U.S., note that some plans require certain immigration status, state residency, and/or income qualifications.
Also review extras such as preventive care, mental health, wellness programs, and maternity coverage.
Remember: a low price doesn’t automatically mean the best option—it must fit your (and your family’s) specific needs.
The U.S. health insurance market includes a range of public and private plans.
Here are key options you should know.
Plans under the Affordable Care Act (ACA) are offered through federal/state marketplaces. They must include essential health benefits and prescription coverage. Income-based subsidies may lower costs.
A public program for people with low incomes; covers children, pregnant people, people with disabilities, and families. Usually no premium; some services may have small copays.
A program for people 65+ (and some with disabilities). It’s divided as follows:
Private coverage can be purchased directly or provided as an employer benefit. These plans vary in coverage levels and typically include broad provider networks.
Remember: beyond a policy, a health plan is protection for you and your family—take the time to choose well.
Here’s a comparative table of major U.S. health plan types.

For immigrants in the United States, finding a legal way to remain in the country indefinitely can be a long and confusing process. That’s why it’s important to know all the alternatives to help pave the way toward lawful permanent residence.
Getting a sponsor is a path that can help you regularize your immigration status in the United States. A sponsor is a person who assumes legal and financial responsibility for someone who is in the process of regularizing their documents in the country.
Below, we explain in detail what a sponsor is, the income table to sponsor a family member in 2025, and all the forms and documents needed to formalize this process.
In simple terms, a sponsor is a person who takes on legal and financial sponsorship of someone who is in the process of obtaining an immigrant visa or a Green Card.
It’s a measure by which the U.S. Government, through USCIS, ensures the sponsored person will not become a public charge, since sponsorship entails the sponsor’s financial and legal responsibility.
During this process, some terms can be confused and are worth clarifying—namely sponsor and petitioner.
On the other hand, there are two relevant forms you should know during this process.
This form is generally used for permanent resident visas, employment-based visas, or family-based Green Cards for immediate relatives.
This form is required for temporary or nonimmigrant visas—for example, a tourist or fiancé(e) visa.
These are the requirements your sponsor must meet to proceed:
Regarding income requirements, sponsors must meet the minimums set by the Department of Health and Human Services (HHS), which requires household income above 125% of the federal poverty guideline.
Household size includes the sponsor, their spouse, dependent children, and the sponsored immigrant.
Below is a comparative table with the minimum figures by household size.
| Household size | For sponsors on active duty in the U.S. Armed Forces sponsoring a spouse or child | All other sponsors | Alaska | Hawaii |
|---|---|---|---|---|
| 2 | $21,150 | $26,437 | $33,037 | $30,400 |
| 3 | $26,650 | $33,312 | $41,637 | $38,312 |
| 4 | $32,150 | $40,187 | $50,237 | $46,225 |
| 5 | $37,650 | $47,062 | $58,837 | $54,137 |
| 6 | $43,150 | $53,937 | $67,437 | $62,050 |
| 7 | $48,650 | $60,812 | $76,037 | $69,962 |
| 8 | $54,150 | $67,687 | $84,637 | $77,875 |
| Each additional person | $5,500 | $6,875 | $8,600 | $7,913 |
If the sponsor does not meet these minimum incomes, you can turn to a joint sponsor or a household member.
It’s also important to consider some special cases.
To formalize sponsorship, the sponsor must sign an affidavit committing to provide legal and financial support.
By signing the affidavit of support, the sponsor commits to providing the financial resources necessary so the sponsored person does not become a public charge.
If the immigrant receives public assistance, such as Medicaid, the U.S. Government may require the sponsor to reimburse those funds.
Sponsorship has no fixed duration, but it can end when:
In marriage-based sponsorship, divorce does not terminate the sponsor’s obligations. The same applies if the parties stop living in the same household.
Finally, it’s essential to know the documents needed to formalize sponsorship and to assess your sponsor’s eligibility.
This form serves as an affidavit in which the sponsor commits to meeting their economic and legal obligations to the sponsored person.
There is no fee to file these forms. Unless filed from outside the U.S. through the National Visa Center, in which case Form I-864 costs $120.
The sponsor must present documents proving U.S. citizenship or lawful permanent residence—for example, a passport, Green Card copy, or naturalization certificate.
You must provide the most recent annual tax return (Form 1040) and proof of income.
An employer letter may also be required to confirm the sponsor’s position, salary, and length of employment.
The sponsor must show a U.S. domicile and residence there. Deeds or utility bills can serve as proof.
Throughout this article, we reviewed in detail what a sponsor is—a person who assumes legal and financial responsibility for an immigrant—as well as the minimum income table and required documents.
Even with a sponsor’s support, it’s important to continue legalizing your situation in the country and to obtain steady work and income.
To that end, it’s vital to manage money well and have fair financial services suited to you.

If your income does not reach 125% of the Poverty Guidelines, you can look for a joint sponsor who must meet the same requirements—per the Federal Poverty Guidelines published annually by the Department of Health and Human Services (HHS).
The primary sponsor and joint sponsor are responsible for reimbursing the Government for any public assistance the sponsored immigrant receives.

Despite the fact that digital payment methods have gained significant relevance practically worldwide, checks remain essential for carrying out certain transactions, especially for people without a banking account.
According to recent data, 61% of Americans still use checks. However, 17% have been victims of check fraud.
Knowing how to endorse a check in the United States is a necessary security measure to prevent fraud. While it can be a confusing procedure, it is crucial to understand it in order to avoid issues.
In this article, we will explain step-by-step how to correctly endorse checks, as well as the information you need to write on the back in order to cash the stated amount.
A check endorsement is a signature on the back of the check that serves as authorization for it to be cashed at a financial institution.
Its main function is to validate the cashing of the check, as well as authorize the transfer of funds, or to transfer the right to another person.
Knowing how to endorse a check is essential because it is a primary security requirement in the U.S. financial system, serving as a protection measure for the holder and the deposited funds.
Below, we show you how to complete the endorsement before cashing checks at the bank.
Make sure the details on the front of the check are correct, such as the payee’s name, the amount in numbers and words, and the banking institution.
Turn the check over and locate the statement “Endorse Here” or “Do not write below this line.” Avoid writing below the marked area.
Sign the check in the designated box, according to the type of endorsement you require. Next, we will explain everything about the different types.
But what should you do if the payee’s name is incorrect?
If the payee’s name is incorrect, you should first sign as it appears and then sign again with the corrected name.

A restrictive endorsement is a security measure to prevent an unauthorized third party from cashing the check, as it limits the form of payment to a registered banking account. It is linked to the information provided on the back of the check.
If the check is made out to more than one payee, one or all may need to sign the endorsement, depending on how it is written.
Before endorsing your check, verify which type is most suitable depending on the transaction you need to perform. For example, a restrictive endorsement is a way to secure your money, just like using modern financial alternatives such as Común, a comprehensive service that gives you access to unified and efficient financial tools.
A blank endorsement is carried out when the same payee cashes the check in cash. In this case, only the signature in the designated area is needed.
A restrictive endorsement is a security measure to ensure that the funds are deposited into a specific banking account.
To do this, you must include the statement “for deposit only to” + bank name, account number, and signature.
This is the most recommended method for Común users who make deposits via mobile, as it provides protection for the check in case of loss and ensures that the money is deposited into the designated account.
If the check will be cashed by a third party, it must be endorsed as follows.
Pay to the order of: (name of another person) + signature
It is important to exercise extreme caution with this type of endorsement. Use it only with trusted individuals, and in case of theft or loss of a check, report it to the financial institution immediately.
A business endorsement is made when a check is cashed in the name of a company. This requires including the full name of the company, followed by the signature of the authorized legal representative.
To deposit check funds through a mobile application or mobile banking, it must be endorsed as follows:
For mobile deposit only + your signature.
Cashing checks is a process that requires special care and attention in order to avoid mistakes and setbacks that could affect the transaction.
This time, we learned the importance of correctly endorsing a check in the United States, as well as the different types that exist, according to the available cashing methods.
Now that you know how to fill out a check on the back, you can rely on Común to deposit the funds through the mobile app.
Skip the lines: Deposit your check from the app; availability of funds may vary.

Getting a stable and well-paid job is the main goal of thousands of immigrants who come to the United States in search of a better quality of life.
For this reason, it’s essential to have an optimized resume (“CV”) that summarizes personal information, work experience, academic background, and all relevant details for recruiters and hiring managers.
You’ve probably faced the challenge of writing and refining a CV to apply for a job in your home country.
However, knowing the standards in Latin America is not enough, as U.S. resumes have key differences, such as length and focus on measurable results.
Mastering a new resume format can be challenging, and the process can be frustrating if you don’t hear back after sending multiple applications.
This doesn’t necessarily mean you lack the required skills — your resume might simply need some adjustments to get noticed by U.S. recruiters.
In this article, we aim to make the process easier for immigrant job seekers through a complete guide and sample resumes that will help you create your own by the end of the reading.
Even if you know how to write a resume in Latin America, it’s essential to understand the key differences compared to the U.S. standard.
Here are the main differences between a professional CV in Latin America and a U.S. resume.
In Latin America, it’s common to see two-page CVs, while the American resume is usually limited to one page.
U.S. recruiters look for quantifiable data and measurable results, while in Latin America it’s more common to include task descriptions and responsibilities.
To prevent discrimination, U.S. resumes do not typically include a photo, age, or nationality.
The use of ATS (Applicant Tracking Systems) to detect keywords is widespread among U.S. companies.
While Latin American CVs often use colorful or elaborate designs, U.S. recruiters prefer minimalist formats to make information easier to read.
Understanding these differences is crucial for immigrants, as it increases the chances of being considered by both recruiters and automated systems.
Here’s a step-by-step guide to writing a strong U.S. resume that passes ATS filters and captures recruiters’ attention.
Avoid flashy designs, as they can make reading difficult and hurt your ATS score. Choose a clean, organized, and easy-to-scan format.
Include your full name, U.S. phone number, professional email address, and LinkedIn profile link.
Remember that you do not need to include a photo, date of birth, or marital status.
Your profile should be concise and include relevant keywords. This section should be a short paragraph summarizing your work history, interests, achievements, and career goals.
It’s essential to list your work experience clearly and in chronological order.
To write your professional achievements, use the XYZ formula, structured as follows:
For example:
“Improved the brand’s visual identity through an e-commerce rebranding project, reducing cart abandonment by 50%.”
List your academic background, including institution name, degree, and attendance dates.
The skills section is key to making your resume stand out.
It’s recommended to separate this section into soft skills and technical skills.
Depending on the vacancy and your profile, you can include additional sections, such as languages, certifications, or volunteer experience.
This information can set you apart from other candidates, as it gives you additional skills that could be relevant to the position.
Here’s an example of how an optimized resume should look, according to U.S. company standards.
On this page, you can download CV templates in English to customize yours according to your experience.
The last step is to adapt this example to your own professional profile and career path, which may differ depending on whether you are a recent graduate or already have experience.
Here are some things to avoid when writing your resume.

Nowadays, making purchases with a credit or debit card in physical stores and online is an essential activity for acquiring everyday goods.
Security in these operations is essential. For this, these payment methods use the CVV or CVC code, which means Card Verification Value or Card Verification Code respectively, and its purpose is to verify that the cardholder has the physical card and to protect online and phone purchases.
Below, we will explain in detail what the CVV is, where to find it, the types of security codes, and tips to keep your cards secure.
If you are going to make purchases online or by phone, you will need to provide the security code of your debit or credit card to verify it belongs to you.
In most cases, the CVV is located on the back of the card and consists of 3 or 4 numbers.
Here is a quick guide to locating the verification code depending on the card type.
Card type
Where to find the CVV?
How many digits does it have?
Visa
Usually on the back, next to the magnetic stripe.
3
Mastercard
Usually on the back, next to the signature.
3
Discover
Usually on the back, to the right of the signature.

American Express
Usually on the front, next to the card number.

One way to strengthen security during electronic transactions is the use of a dynamic CVV, which is found in digital applications or cards and is valid only for a limited time to make a single purchase. This reduces the risk of misuse of your personal data if it is exposed.
The CVV number is a security lock that allows you to use your physical and digital cards with confidence that a third party cannot access your money.
These are the most important functions of this security code.
It is especially useful for protecting electronic operations by verifying that the cardholder is the one making the purchase.
When making an online purchase, you must enter the card’s CVV to validate the transaction. This process is more secure when using a dynamic CVV because it reduces the risk in case of fraud.
Unlike other data usually included on physical cards, such as the number and expiration date, the CVV is not stored in online store systems, so your data remains safe in case of potential identity theft.
The purpose of the CVV is to provide you with security and peace of mind when making online purchases.
You may notice different types of CVV since the name can vary depending on the card issuer.
These are the security codes most commonly used by financial institutions to protect users’ cards.
The CVV (Card Verification Value) is the security code created for Visa cards. It consists of 3 or 4 digits and is used to confirm that the person making the purchase actually has the card.
The CVC (Card Verification Code) is the version of the CVV used by Mastercard cards. It has the same function and a similar composition.
The CVV2 (Card Verification Value 2) is a digital version of the CVV used to provide greater protection in online purchases. While the traditional CVV is used during payments at card terminals, the CVV2 is requested to confirm remote transactions.
Some people avoid or minimize the use of physical or digital cards due to fear of having their personal data stolen and generating unauthorized charges. However, financial institutions and digital platforms currently offer the necessary security measures to protect your assets.
Thanks to the implementation of codes such as the CVV, the risk of experiencing a security incident is minimal and decreases even more when you have the right information to apply practical strategies like the following.
Bank cards are useful tools that require responsible and cautious use. Learning to use your card safely and confidently is also part of building financial stability.
This time we explained what the CVV or CVC is, why it is important, and gave you some tips to keep your checking accounts secure.
The security provided by the CVV is the same you need in all your financial operations, such as digital payments, cash deposits, and international money transfers. For this, you have Comun, the digital platform specially designed for immigrants living in the United States who want to manage their money safely and without complications, with clear and competitive fees.

If you still have questions, check the following section.
It is not advisable to give your CVV to someone else, as they could make purchases not authorized by you. Make sure to protect your banking information so only you have access to it.
No, the card number consists of 16 digits and identifies the checking account. The CVV consists of 3 or 4 digits and verifies that the holder is the card owner.
In physical stores, it is not strictly necessary, as the purchase is validated with the chip and PIN. For online purchases, it is essential to enter the CVV to authorize the transaction.
