This is bank-specific, so I guess whatever you said.:-) Number D is eventually a card code (GD is Giesecke & Devrient) On American Express cards this is 4 digits, and they appear on the front of the card. The purpose of the code is to verify that a payment card is actually in the hands of the cardholder/merchant, for example when using the card over the internet or phone.

By these 6 digits anyone can know which institution issued the card, and what type of card it is (debit/credit, premiere or not, etc). First digit is 4 for VISA, 5 for Mastercard, 6 for Discover/Diners Club, 3 for American Express/Diners Club (those are shorter than 16).Īlso, first 6 digits for Visa and Mastercard are code numbers for the issuing institution.
