CVV2 & CVC2 Information
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.
