On the back of your credit card, you should find your account number
printed somewhere either above or below the signature block. Following the account account
number are 3 additional digits. This is the Customer Identification Number we
are looking for. This provides additional assurance that only someone in
possession of your credit card can use it for mail or internet purchases. This
protects both our customers and ourselves against fraudulent
purchases. If the extra 3 digits are not on your card, please enter "XXX".
