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.
On Visa, MasterCard, and Discover cards, the code is a three-digit code on the back of your card. The preceding four digits (â3456â in the image above) are the last four digits of your card number. On American Express cards, the security code is a four-digit code on the front of the card. Look above your card number on the right side of the card. Your security code, like all the other numbers on your card, is a critical piece of information.
