What is BIN 340873?
BIN 340873 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.
Payment processors read these digits on every transaction: they drive routing decisions, currency handling at checkout, fraud scoring and card-product acceptance rules. BIN 340873 carries no personal information: it maps to an issuing institution and card program, never to an individual account or person.
