If your credit card does not have one of the codes, please contact your credit card company to get a new credit card to allow processing your credit card in secure way.
Information
Mail order and telephone order (MO/TO) and other card-not-present transactions have higher fraud rates than face-to-face transactions. When a card's magnetic stripe is read by a point-of-sale (POS) terminal, Visa's Card Verification Value (CVV) or MasterCard's Card Validation Code (CVC) can be verified during the authorization. However, when the card is not present the CVV or CVC cannot be validated. To help reduce fraud in the card-not-present environment, acquirers, merchants, and issuers can use the CVV2 or CVC2 program. Even if a criminal steals a valid account number, they cannot compute the CVV2 numbers since they do not know the mathematical algorithm logic.
What is CVV2 or CVC2?
The CVV2/CVC2 is a three-digit security code that is printed on the back of cards. The number appears in reverse italic at the top of the signature panel at the end (see sample). This program helps validate that a genuine card is being used during a transaction. All MasterCard cards, both credit and debit, were required to contain CVC2 by January 1, 1997; all Visa cards must contain CVV2 by January 1, 2001.
How does CVV2 or CVC2 Work?
Card-not-present merchants are being directed to ask cardholders for CVV2/CVC2 when cardholders place orders. Merchants ask the cardholder to read this code from the card. The merchant then asks for CVV2/CVC2 verification during the authorization process. The issuer (or processor) validates the CVV2/CVC2 and relays the decline/approve results during the authorization process.
Changes to signature panel?
Previously the three-digit CVV2 or CVC2 number followed the 16-digit account number printed on the card's signature panel. The 16-digit account number is now truncated to four digits on the signature panel. Beginning March 31, 2000, cards will show the last four digits of the account number followed by the three-digit CVV2 or CVC2 number on the card signature panel. This change makes it easier for cardholders to sign their cards.
