CVV2, or Card Verification Value, is a number that is printed, not imprinted, on your Visa, Mastercard, American Express, or Discover. This number is never transferred during card swipes and should only be known by the cardholder, the person holding the card in their hand. Visa, Mastercard, and Discover card members can find their CVV2 number in the signature area of your card. Your card number should be printed here along with a three-digit number at the end. This is your CVV2 number.
American Express card members can find their CVV2 number printed above and to the right of the imprinted card number on the front of the card.
