BIN 552794 — Lookup & Card Details

BIN 552794 is issued by China Guangfa Bank Co., Ltd, from China, on the mastercard 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 552794, that institution is China Guangfa Bank Co., Ltd in China. The card runs on the mastercard 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 552794 itself is public metadata — it identifies the issuer, not the cardholder.
