BIN

A BIN, or bank Identification number, identifies the financial institute that issued a credit card (the issuer). The first set of digits of a credit card’s PAN (primary account number) consist of the BIN. The BIN can be up to 8 digits long. The BIN provides merchants with additional information. As well as the issuing bank, the BIN also includes information on the card brand, country of origin, the card’s level (business, platinum etc.) and card type (pre-paid, gift, credit etc.). The BIN is also referred to as IIN, or issuer identification number.

The first digit of the BIN is the major industry identifier (MII), which indicates the type of institution that issued the card (e.g. 4 or 5 indicate banking and financial institutions).

How can merchants benefit from knowing the BIN?
