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. For BIN 402639, that institution is National Bank Of Kuwait, S.A.K. in Bahrain. The card runs on the Visa network. Transactions settle in BHD.

Visa is the world's largest card network, with cards beginning with the digit 4 and accepted in virtually every country.

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 402639 itself is public metadata — it identifies the issuer, not the cardholder.
