What is BIN 521925?
BIN 521925 is on the Mastercard 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 Mastercard network.
Mastercard is a global network whose BINs fall in the 51–55 and 2221–2720 ranges, accepted at merchants worldwide.
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 521925 itself is public metadata — it identifies the issuer, not the cardholder.
