Help: Card Code "CSC" |
| The Card Security Code (CSC) is a number separate
from the credit card number that is printed on your
credit card. It is used to help with fraud prevention
by verifying that you have the physical card in your
possession. If your card has a CSC we require that you
enter it. |
 |
| Visa, MasterCard, and Discover:
the CSC is the last 3 numbers printed on the back
of the card in the signature field. |
|
American Express: the CSC is
the 4 non-embossed numbers printed on the front of the
card above the credit card number. |
