Frequently asked questions

Which card networks does Firstmark Credit Union issue?

In our data Firstmark Credit Union has 10 BINs: Visa (5 BINs), Mastercard (5 BINs). 60% are debit ranges and 40% credit ranges.

What are the first 6 digits of a Firstmark Credit Union card?

The first 6 digits are the BIN. Firstmark Credit Union BINs include 400765, 434368, 514525; the table above lists all of them. A BIN identifies the bank and card type, never a person or an account.

Can I make a real, usable Firstmark Credit Union card number from a BIN?

No. A number built from a BIN passes format checks (prefix, length and the Luhn check digit), but no bank issued it, so every real payment with it is declined. To test a checkout use your payment gateway’s sandbox test cards; to pay online without exposing your card, ask Firstmark Credit Union or another issuer for a virtual card.

A BIN identifies the card network and the issuing institution only. It reveals nothing about an individual card, cardholder or account, and it cannot show whether a card exists or can be charged. Test numbers generated from a BIN are for development and QA only and are declined by every real payment system.
