A CVV number is a 3- or 4-digit security code used to help verify that you have the card when making a payment. On most Visa, Mastercard, and Discover cards, the CVV is the three-digit code on the back. On American Express cards, it is usually a four-digit code on the front.
If you are using a virtual card, you can usually find the CVV alongside your card number and expiry date in your provider’s app or dashboard.

What is a CVV number?
CVV stands for Card Verification Value. It is a security code linked to your payment card.
You may need to enter it when paying online or over the phone, especially when the physical card is not being used. These are known as card-not-present transactions.
The CVV gives the merchant another piece of information to check alongside your card number and expiry date.
It is important to note that a CVV is not a guarantee that a transaction is safe. Not every merchant requires it, and other fraud checks may also be used.
Where is the CVV on a card?
The location depends on the card network.
Visa, Mastercard and Discover
On most Visa, Mastercard and Discover cards, the CVV is a three-digit number on the back of the card.
It is usually printed near the signature panel.
Do not confuse it with the last four digits of your card number. They are different numbers and serve different purposes.
American Express
American Express cards usually have a four-digit security code on the front of the card.
This code is often located above the card number.
So, if a website asks for a CVV and your American Express card does not have a three-digit code on the back, check the front instead.
How many digits is a CVV?
A CVV can contain three or four digits, depending on the card network.
- Visa: usually 3 digits
- Mastercard: usually 3 digits
- Discover: usually 3 digits
- American Express: usually 4 digits
This is why saying that every CVV is three digits can be misleading.
If a payment form asks for a three-digit CVV and your card has a four-digit security code, check whether you selected the correct card type.
Is CVV the same as CVC, CSC, CID or CVV2?
You may see different names for the same type of card security code.
| Term | Commonly associated with |
|---|---|
| CVV | Visa and general usage |
| CVC | Mastercard |
| CSC | Card Security Code |
| CID | American Express and Discover |
| CVV2 | A second-generation card verification code |
The names can vary by card network and issuer, but the basic purpose is similar: help verify card details during a payment.
American Express, for example, uses the term CID for its four-digit security code, while Mastercard commonly uses CVC.
What is a CVV used for?
A CVV is mainly used as an additional security check when you make a card payment.
For example, when you buy something online, you may be asked for:
- Your card number
- Expiry date
- Name on the card
- CVV
The merchant sends the relevant payment details through its payment processor and card network. The issuer can then approve or decline the transaction based on the information and other checks.
The CVV can help reduce certain types of card fraud because someone who only has your card number may not have the security code.
However, not every merchant checks CVV, so having or knowing the CVV does not by itself determine whether a transaction will be approved.
How does CVV verification work?
When you enter your CVV during an eligible card payment, the payment system can use it as part of its verification process.
A simplified payment flow looks like this:
You → Merchant → Payment processor → Card network → Card issuer
The issuer or payment system can check the payment details and apply additional fraud controls before approving or declining the transaction.
For online payments, this is useful because the merchant cannot physically inspect your card.
The CVV is therefore one piece of the larger payment-security process, rather than a standalone security system.
CVV vs card number vs expiry date vs PIN vs OTP
These numbers can be confusing because you may be asked for several of them during a payment.
Card number
The card number identifies the card account used for the transaction.
It is usually the long number displayed on the front or back of a physical card, or inside a virtual-card interface.
Expiry date
The expiry date tells the payment system when the card expires.
It is normally shown as a month and year.
CVV
The CVV is the additional security code used for certain card payments.
It is usually three digits, although some cards use four.
PIN
A PIN is a personal identification number used to authenticate certain transactions, such as ATM withdrawals and some in-person card payments.
It is not the same as your CVV.
You should never enter your card PIN into a website simply because the website asks for a CVV.
OTP
An OTP, or one-time password, is a temporary code sent or generated for authentication.
It is different from your CVV and normally changes from one authentication attempt to another.
Where is the CVV on a virtual card?
A virtual card does not have a physical surface where the CVV can be printed.
Instead, the card details are displayed digitally.
A typical virtual card gives you:
- Card number
- Expiry date
- CVV or security code
If you’re new to virtual cards, learn how virtual cards work to understand how the digital card connects to online payments.
For most virtual-card providers, you can reveal your CVV by opening the card details in the provider’s app or dashboard.
Where can you find the CVV on an EverTry virtual card?
With an EverTry virtual card, your card details are available digitally rather than on a physical card.
After creating your card, open the relevant card details in your EverTry account to view the information needed for an eligible payment, including the card number, expiry date and CVV.
If you are comparing virtual card options, you can also learn how to choose a virtual dollar card based on factors such as funding methods, fees, spending limits and where you need to use the card.
The important difference is simple: a physical card has its CVV printed on the card, while a virtual card displays it digitally.
Can you use a card without the CVV?
Sometimes.
A CVV is not required for every card transaction. Whether it is requested depends on the merchant, payment method and transaction type.
For example, you may not be asked for a CVV when using a saved payment method or making certain transactions.
That means the statement “you cannot buy anything without a CVV” is too broad.
The CVV is an additional verification method, not a universal requirement for every card payment.
Is it safe to share your CVV?
Treat your CVV as sensitive card information.
You may need to enter it into a legitimate payment page when making a purchase. However, you should not casually send your CVV to people through messages, social media, or email.
Be especially careful if someone asks for your:
- Full card number
- CVV
- Expiry date
- PIN
- OTP
A legitimate payment provider will not need you to publicly post these details.
Also check the website carefully before entering your card information. A fake payment page can collect your card number and CVV even if the page looks convincing.
What should you do if someone gets your CVV?
If you think your card details have been exposed, act quickly.
Depending on your card provider, you may be able to:
- Freeze or block the card.
- Review recent transactions.
- Report transactions you do not recognize.
- Replace the card if necessary.
- Contact the card issuer for further help.
A CVV being exposed does not automatically mean someone can successfully use your card. Other checks may apply. However, it is still a good reason to review your account and take precautions.
Virtual cards can also give you more control over online spending because some providers allow cards to be frozen, deleted or limited.
What if you cannot find your CVV?
If you have a physical card:
- Check the back near the signature panel.
- If it is an American Express card, check the front.
- Make sure you are looking for a three- or four-digit security code rather than the last four digits of your card number.
If you have a virtual card:
- Open your card in the provider’s app or dashboard.
- Look for the card details.
- Check for the CVV or security code field.
If the code is not visible, contact your card provider rather than guessing the number.
What can you use a virtual card for?
A virtual card can be useful for many online payments where the card type and transaction are supported.
Common examples include:
- Software and SaaS
- AI tools
- Online advertising
- Streaming subscriptions
- Online shopping
- Digital services
- Travel bookings
- Online courses
