What is the CVV Number?

CARD VERIFICATION VALUE CODE (CVV)

cvv examples

CVV is a new authentication procedure established by credit card companies to further efforts towards reducing fraud for internet transactions. It consists of requiring a card holder to enter the CVV number in at transaction time to verify that the card is on hand.The CVV code is a security feature for "card not present" transactions (e.g., Internet transactions), and now appears on most (but not all) major credit and debit cards. This new feature 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 calls it CVC2, and American Express calls it CID.)
