What is BIN 421821?

BIN 421821 is on the Visa 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 Visa network.

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

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 421821 itself is public metadata — it identifies the issuer, not the cardholder.
