What is BIN 621743?

BIN 621743 is on the UnionPay 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 UnionPay network.

UnionPay is China's card network and one of the largest in the world by cards issued; its BINs begin with 62 and are accepted in over 180 countries.

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 621743 is institutional data under the ISO/IEC 7812 standard — looking it up reveals the issuing program, nothing about any cardholder.
