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.
Turn your card over and look at the signature box. You should see either the entire 16-digit credit card number or. just the last four digits followed by a special 3-digit code. This 3-digit code is your CVV number / Card Security Code.American ExpressÂ® cardholders: Look for the 4-digit code printed on the front of your card just above and to the right of your main credit card number.This 4-digit code is your Card Identification Number (CID).merican ExpressÂ® cardholders: Look for the 4-digit code printed on the front of your card just above and to the right of your main credit card number.
