CVV Code

The CVV code (Credit Card Verification code) is an authentication procedure established by credit card companies to further efforts towards reducing fraud for Internet transactions. This code is a three- or four-digit code which provides a cryptographic check of the information embossed on the card. Therefore, the CVV code is not part of the card number itself.

The CVV code helps ascertain that the customer placing the order actually possesses the credit/debit card and that the card account is legitimate. Each credit card company has its own name for the CVV code, but it functions the same for all major card types. (Visa refers to the code as CVV2, MasterCard alls it CVC2, and American Express calls it CID.)

For Visa and Mastercard, the CVV code may be found on the back of the card, on the signature strip. It is the three digit number that follows the credit card number.

For American Express, the CVV code is a four digit number and is found on the front of the card above and either to the right or the left of the card number.
