What is the CCID (Card Identification Number) or CVV (Card Verification Value) and what does it look like?

For your protection, we ask that you enter an extra 3-4 digit number called the CCID. The CCID is NOT your PIN number. It is an extra ID printed on your Visa, MasterCard, Discover, or American Express Card.
Visa, 3-digits in reverse italic to the right of the cc number in the signature area on back.
MasterCard, 3-digits in reverse italic to the right of the cc number in the signature area on back.
Discover, 3-digits in reverse italic to the right of the cc number in the signature area on back.
American Express, 4-digits printed (not embossed) on the right front of the card above the cc number.
