What is BIN 344321?
BIN 344321 is on the American Express network.
A Bank Identification Number (BIN, or Issuer Identification Number / IIN) is the first 6 to 8 digits of any payment card. It tells the payment network which institution issued the card, what kind of card it is, and where it was issued. The card runs on the American Express network.
American Express cards begin with 34 or 37 and run on Amex's own closed-loop network.
Merchants, fraud teams, ad platforms and developers use BIN data to route transactions, localize checkout, detect chargebacks and decide which card products they accept. BIN 344321 itself is public metadata — it identifies the issuer, not the cardholder.
