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 Discover network.

Discover is a U.S.-based network whose BINs include 6011, 65 and the 644–649 ranges, with international acceptance via partner networks.

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 644934 itself is public metadata — it identifies the issuer, not the cardholder.
