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.
VisaÂ®, MastercardÂ®, and DiscoverÂ® cardholders: 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). The CID is the four-digit code printed just above the Account Number.
