• American Express: The card Security Code (also referred to as the CID number) is printed above the imprinted card number on the front of the card (on either the left or right). ** ** Please note, there are a small percentage of 'plastic-less' card accounts for American Express - Corporate and Purchasing Card accounts. If you have one of these accounts with no AMEX card, please enter 5555 as your card security code. I want a printed eCard to present to someone as a gift. How do I do this?
