ISO/IEC DIS 7812-1(EN) Identification cards — Identification of issuers — Part 1: Numbering system

ISO/IEC 7812-1 was created by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 17, Cards and personal identification.
ISO/IEC DIS 7812-1 is the fifth edition, it cancels and replaces the fourth edition (ISO/IEC 7812-1:2015), which has been technically revised.
ISO/IEC DIS 7812-1 specifies a numbering system for the identification of the card issuers, the format of the issuer identification number (IIN) and the primary account number (PAN).
ISO/IEC DIS 7812-1 is one of a series of International Standards specifying a numbering system for the identification of card issuers operating within an interchange environment, the format of the issuer identification number and the primary account number. Card issuers not operating in an international interchange environment are encouraged to contact their sponsoring authorities for a number assigned by that national standards body, or the Registration authority (RA) if no Sponsoring Authority (SA) exists. Use of a national IIN will avoid conflicts if the cards are used in an international interchange environment.
Terms and definitions:
Institution (or its agent) which acquires from the card acceptor the data relating to the transaction and initiates the data into an interchange system
Form factor (physical or virtual) provided by a card issuer
