We request a Credit Card Verification Number on all transactions for your protection. The card verification number is printed on your Visa, MasterCard & Discover cards in the signature area of the back of the card. (it is the last 3 digits AFTER the credit card number in the signature area of the card).
American Express cards show the card verification number printed above and to the right of the imprinted card number on the front of the card.
If you have one of the above cards but do not have the new verification number printed on the card, you will need to either choose a different card or contact your credit agency and request the verification number and/or a new card with the number printed on it.
