BIN 437594 — Lookup & Card Details

BIN 437594 is issued by United Commercial Bank, from Bangladesh, on the Visa network, as a credit card.

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 437594, that institution is United Commercial Bank in Bangladesh. The card runs on the Visa network. Transactions settle in BDT.

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

In practice this prefix is what a checkout sees first — risk engines score it, gateways route on it, and merchants use it to decide whether to accept the card class at all. BIN 437594 is institutional data under the ISO/IEC 7812 standard — looking it up reveals the issuing program, nothing about any cardholder.
