For your protection, we ask that you enter an extra 3-4 digit number called the CCID. (It may also be referred to as a CVV2 or CVC2 code.) The CCID is NOT your PIN number. It is an extra ID printed on your Visa, MasterCard, or American Express Card.
Visa and
MasterCard: On the back of the card in the top-right
corner of the signature box. Enter the three-digit number following the
credit card number. (See example.)
American
Express: On the front of the card. Enter the four-digit number
on the right directly above the credit card number. (See example.)
