BIN 400578 — Lookup & Card Details

BIN 400578 is issued by Bank Of China Limited, from China, on the visa network, as a debit 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 400578, that institution is Bank Of China Limited in China. The card runs on the visa network. Transactions settle in CNY.

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 400578 itself is public metadata — it identifies the issuer, not the cardholder.
