Turn your card over and look at the signature box. You should see either the
entire 16-digit credit card number or just the last four digits followed
by a special 3-digit code. This 3-digit code is your CVV number / Card Security Code.
American Express® cardholders:
Look for the 4-digit code printed on the front of your card just above and to the right
of your main credit card number. This 4-digit code is your Card Identification Number (CID).
