BIN, the acronym for a bank identification number, is the first four to six-digit numbers on credit or debit cards. These numbers inscribed on debit or credit cards reveal or identify the company that issued them. It is also crucial during the process of tracing a transaction to the authorizer of a card.
The American National Standards Institute (ANSI) and the International Organization for Standardization (ISO) developed this bank identification number to identify companies or institutions that issue various cards.
This bank identification number applies not only to debit cards or credit cards, but also to prepaid cards, electronic benefit cards, gift cards, and charge cards.
