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.
The CVN code is a special 3-4 digit code used as a security measure for all Internet transactions. It is called CVV2 (Credit card Verification Value) for Visa cards and CVC2 (Credit card Verification Code) for MasterCard. Since the CVN is listed on your credit card, but is not stored anywhere, the only way to know the correct number for your credit card is to physically have possession of the card itself. Because of this, it is a security enhancement against misuse of credit cards. All VISA, MasterCard and American Express cards newer than 5 years have a CVN. Note: The CVN code is printed on your card; it is not raised from the surface of the card like your credit card's account number.
