What is CVV in a Debit Card, and How Does CVV Work?

3 minutes, 15 seconds Read

CVV, or Card Verification Value, is a three-digit code located at the back of your debit card if you are wondering what the CVV number in the debit card is. It serves as an extra layer of security for online purchases while making payments. The CVV ensures it’s you who is using the card for online transactions. Simply put, it’s a way to confirm that the card is with you when you use it. Now, let’s learn how it works during your transactions.

Working of CVV During an Online Transaction

Now that you know what the CVV number in the debit card is, it’s essential to learn how it works. When you make an online purchase using your debit card, you will be asked to enter the CVV code, card number, and expiration date. The merchant does not store the CVV code or the payment gateway, which means it’s an extra layer of security only you should know.

During the transaction, the CVV code is encrypted and sent with the transaction details to the card issuer’s server for verification. The card issuer checks the CVV code to ensure it matches their records. If the CVV code is correct, the transaction is approved, and the payment is processed.

However, if the CVV code is incorrect, the transaction will be declined, and you will be asked to try again with the correct code or use an alternative payment method. This helps prevent fraudulent transactions, as even if someone has stolen your card number, they won’t be able to use it without the CVV code.

Why is CVV asked, and is there an alternate method for secure payment via debit card?

Here are some pointers to help you understand why the CVV is important and if there are any alternative methods for secure payment via debit card:

  • CVV is a security feature: The CVV is not stored in the magnetic stripe or chip of the card, making it difficult for fraudsters to obtain it. When you provide the CVV during a transaction, it confirms you have the physical card in your possession.
  • CVV protects against fraud: If a thief steals your card number, they still need the CVV to complete a transaction. With the CVV code, the payment will be accepted, preventing unauthorised purchases.
  • Use secure payment gateways: When making an online payment, ensure you use a secure payment gateway that encrypts your data and protects it from prying eyes.
  • Consider using virtual cards: Some banks offer virtual debit cards that generate a unique card number and CVV code for each transaction. This adds an extra layer of security as the card number and CVV code are only valid for a single transaction.
  • Use two-factor authentication: Some banks require two-factor authentication for online transactions, which involves entering an additional code sent to your phone or email, meaning only you can pay using your debit card.

Does my customised debit card have a CVV, and can I customise it too?

When you order a customised debit card, it will come with a CVV number, the three-digit security code on the back of the card. However, the CVV cannot be customised as it is a standard security feature assigned to the card by the bank. Only the design and personalisation elements of the card can be customised according to your preferences.


The CVV code is an important security feature for debit cards that helps prevent fraudulent transactions. It adds an extra layer of security to your online and in-store purchases, ensuring only you can use the card for transactions. It’s essential to keep your CVV code safe and secure and to use secured payment gateways, virtual cards, and two-factor authentication when making payments online. 

Remember, when you order a customised debit card, it will come with a CVV number that cannot be customised, as it is a standard security feature assigned by the bank.
