To help reduce fraud in the card-not-present environment, credit card companies have introduced a card code program. Visa calls this code Card Verification Value (CVV); MasterCard calls it Card Validation Code (CVC); Discover calls it Card ID (CID). The card code is a three- or four- digit security code that is printed on the back of cards. The number typically appears at the end of the signature panel.
For Visa, MasterCard, and Discover cards, the card code is the last 3 digit number located on the back of your card on or above your signature line. For an American Express card, it is the 4 digits on the FRONT above the end of your card number.
