CARD SECURITY CODE.

The card security code (CSC) is usually a 3 - or 4 - digit number, which is not part of the credit card number. The CSC is typically printed on the back of a credit card (usually in the signature field).

On some cards, all or part of the card number appears before the CSC, for example, 1234 567. In this example, 1234 are the last four digits of the credit card number, and 567 is the CSC.

     

American Express 4 digits on front of card		Visa and Mastercard last 3 digits on back of card

The number appears only on the card itself (not on receipts or statements), so provides some assurance that the physical card is in the possession of the buyer. By using CSC you may be able to reduce your charge back rates.

CSC is known by difference names with the different card associations. CSC is known to Visa as the Card Verification Code (CVV2); to MasterCard as the Card Validation Code (CVC2); and finally to American Express as the Card Identification Number (CID).

WHAT IS THIS AND WHY DO I HAVE TO DO IT?

Due to the amount of credit card fraud over the internet, banks will soon REQUIRE this information to process credit card orders online - you can expect to see it used everywhere in the very near future; we just want to get a head start on it. Your benefit is that it prevents any fraudulent charges using your credit card, i.e. no one can pick up an old receipt of yours and use that info to fraudulently use your credit card.
