- Example of a CVV2 number: For most cards, the CVV2 is a 3-digit number (e.g., 123), located on the back of the card near the signature strip.
- For American Express (AMEX), it is a 4-digit number found on the front of the card.

FAQ
How do I find my CVV2 code?
You can find your CVV2 code by looking at the back of your credit or debit card.

For American Express cards, the CVV2 (or CID) is a 4-digit number located on the front of the card, usually to the right of the card number.
Is CVV2 the same as a PIN?

If you enter the wrong CVV2, the transaction will be declined. This happens because the CVV2 is used to verify that the card is in the cardholder’s possession during online transactions. If the code doesn’t match the one on file with your bank, the payment system cannot confirm your identity, which results in the failure of the transaction. To resolve this, double-check the CVV2 and ensure you enter the correct code as it appears on your card.
