Security

The credit card security code, or CSC, refers to the three or four digit number printed on the back of the card. The purpose of the CSC is to make if safer for you to use the credit card when making purchases over the phone or on the Internet. Because the CSC is printed only on the card, not on mailed statements or on receipts, it helps ensure that the person making the purchase has not stolen the credit card number but has the actual card in hand.
