Where is my Card Id?
The Customer Card Number (CID or CVV2) is a three or four digit number that is unique to each card. This additional security feature is designed to protect you by helping to ensure the card is present during the purchase. It is printed only on the card, never on any receipts or statements.

The Card Identification # is the 4 digit, non embossed number printed above your account number on the face of your card. This number is recorded as an additional security precaution.
CVV2: A new Three-Digit Value
An important new security feature for card-not present transactions now appears on the back of most visa cards. This new feature is a three-digit value which provides a cryptographic check of the information embossed on the card.
CVV2's Location:
The CVV2 three-digit value is printed on the signature panel on the back of the cards immediately following the card's account number.
The CVV2 value helps validate two things:
  • The customer has a card in his/her possession.
  • The card account is legitimate.
CVV2 is printed only on the back of card- it is not contained in the magnetic stripe information, nor does it appear on sales receipts.
