What is a BIN Number?

A Bank Identification Number (BIN), also called an Issuer Identification Number (IIN), is the first 6 to 8 digits of a payment card number. These digits identify the institution that issued the card and can reveal the card network (Visa, Mastercard, Amex), the card type (credit, debit, prepaid), the card level (Classic, Gold, Platinum), and the issuing country.

BIN data is widely used in fraud detection, payment routing, currency conversion, and geographic verification to streamline transaction processing and reduce chargebacks.
