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.
Also Known As. The CVC code may be called another name, depending on the card's issuer, network or type. The merchant you use may also determine what it's called. For example, Hilton calls it a CVV, while Skype refers to it as a CVC. A 1 or 2 after the letters refers to the where the code is written on the card. For example, the CVV1 is written in the magnetic strip, while the CVV2 refers to the actual three or four digits printed on the card.
