Definition

Noun: A bank identification number is a unique numerical code assigned to a bank or savings association. This code is used to identify the financial institution in electronic transactions, such as credit or debit card payments. It typically forms the initial digits of a payment card number.

Usage

The term bank identification number is used primarily in the context of banking, finance, and electronic payment systems to specify the issuing institution of a card. * It is a standard term in financial technology and card processing. * It is often abbreviated as BIN.

Examples
  • The payment gateway checks the bank identification number to verify the card's issuer before authorizing the transaction.
