What is ISO-IEC 7812-1:2021?

ISO-IEC 7812-1:2021 is a technical standard that defines identification cards, specifically the structure and numbering system used for the identification of issuers of cardholder accounts. This standard provides guidelines and requirements for the numeric systems used in bank cards, credit cards, and other similar cards.

The Structure of ISO-IEC 7812-1:2021

ISO-IEC 7812-1:2021 has a specific structure for identification cards, which consists of six digits in total. Each digit has a specific meaning and purpose. Let's break down the structure:

Digit 1: Major Industry Identifier (MII) - This digit identifies the industry or sector that issued the card.

Digit 2-6: Issuer Identifier - These five digits identify the specific issuer within the industry or sector identified by the MII.

Together, these six digits provide a unique identification number for each card issuer, ensuring that every card can be easily recognized and categorized.
