What is the Card Verification Code? It is a three-digit number imprinted on the signature panel of Visa, Mastercard, and Discover cards to help card-not-present merchants verify that the customer has a legitimate card in hand at the time of the order. The merchant asks the customer for the CVV code and then sends it to the card Issuer as part of the authorization request. The card Issuer checks the CVV code to determine its validity, then sends a CVV result back to the merchant along with the authorization. CVV is required on all Visa, Mastercard, and Discover cards. Where is the code on my card? Visa and MasterCard credit/debit cards have the three-digit value printed on the signature panel on the back of the card immediately following the card account number. The back panel of most Visa/MasterCard cards contain the full 16-digit account number, followed by the CVV code. Some banks, though, only show the last four digits of the account number followed by the code. American Express cards have a four-digit non-embossed code located on the front of the card.

The verification number is a 3-digit number printed on the back of your card. It appears after and to the right of your card number.

The American Express verification number is a small 4-digit number printed on the front of your card on the right hand side.

CVV information is not contained in the magnetic stripe information, nor does it appear on sales receipts.

What does the code do? The CVV value protects the customer and helps validate the following: The customer has the card in his or her possession. The card account is legitimate. Prevents the use of your Credit Card Number without the matching CVV Code. Contact your bank or card issuer for more details.
