What is the SECURITY CODE?

It is an important telephone Security feature that now appears on the back of most Visa and Master cards, and on the front of American Express. This new code is a three or four digit number which provides a cryptographic check of the information embossed on the card.

The security code helps validate that the customer placing the telephone call actually has the credit card in his/her possession, and that the credit card account is legitimate.

Often referred to as CVV2 (Card Verification Value), CVC2 (Card Validation Code) or CID (Card Identification #), the customer is required to enter the code in at the time of the call to verify the card is on hand. (See diagrams below).

American Express Card Users Look for the 4-digit code printed on the front of your card just above and to the right of your main credit card number.  This 4-digit code is your Card Security Code.
