Why a Need for the BIN Number Lookup?

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.

Features of the Bank Identification Number:

1. Every payment card comes along with a bank identification number clearly and boldly written on the front of each card.
2. The first digit of the bank identification number signifies the primary business identifier, including entertainment, airlines, travel, financial, and banking.
3. While the other digits after the first identify the issuing bank it institution. Take, for example, the Major industry identifier (MII) for a visa credit card is four (4), and this directly falls under the financial and banking category.
4. BIN (bank identification number) can also be referred to as the Issuer Identification Number (IIN).
