Overview
ISO/IEC 7812-1:2017 defines the card numbering system used to identify card issuers and accounts in an international interchange environment. The standard specifies the structure and format of the Issuer Identification Number (IIN) and the Primary Account Number (PAN), including the use of a modulus-10 (Luhn) check digit. ISO/IEC 7812-1:2017 is the fifth edition and works in tandem with ISO/IEC 7812-2 (application and registration procedures).
Key topics and technical requirements
- PAN composition: A PAN consists of three components - the IIN (8 digits), the individual account number (variable: 1–10 digits) and a single check digit. The PAN can be up to 19 digits in total.
- IIN format and ranges:
- IINs are 8 digits in length (revised from 6 in earlier editions).
- Special prefix ranges and uses:
- 00: reserved for non-issuer institutions per ISO 8583-1.
- 80[CCC]: healthcare use, managed by national healthcare registration authorities (CCC = ISO 3166-1 country code).
- 89: telecommunications cards per ITU‑T E.118 (managed by ITU).
- 9[CCC]: reserved for national numbering systems administered by national standards bodies or the Registration Authority (RA).
- Individual account number: Assigned by the card issuer; minimum 1 digit, maximum 10 digits.
- Check digit: Calculated on all preceding PAN digits using the Luhn “double-add-double” modulus-10 algorithm (Annex B provides the algorithm and example).
- Registration and governance: IINs are allocated through procedures defined in ISO/IEC 7812-2 and maintained by the ISO-appointed Registration Authority (RA).
Applications and who uses this standard
ISO/IEC 7812-1:2017 is essential for organizations involved in card issuance, interchange, processing and system integration:
- Banks, card issuers and payment schemes - to register and format IINs/PANs for payments and identification.
- Acquirers, payment processors and gateways - to validate PAN structure and check digits during transaction routing.
- Healthcare and telecommunications organizations - for industry-specific IIN allocations (80 and 89 series).
- National standards bodies and Registration Authorities - to implement and manage national numbering schemes (9 series).
- Card manufacturers, terminal vendors and software developers - to implement PAN validation and interoperability.

Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).

technically revised. Key changes made in this edition:
— Clause 3: added definitions for “acquirer” and “card acceptor”;
— Clause 3: removed the definition of “major industry identifier”;
— Clause 3: removed definition of “registration management group” to ISO/IEC 7812-2;
— Removed previous outline of major industry identifier descriptions;
— Clause 4: revised the length of an IIN to 8 digits (from 6 digits);
— Clause 4: revised the minimum length of a PAN to 10 digits (from 8 digits);
— Annex A: modified A.2 to be the role of the registration authority (from previously being defined as
role of registration management group);
— Annex B: revised the example to reflect an 8 digit IIN.

Introduction
This document 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;
— application and registration procedures for card issuers who operate a card program in an
international interchange environment.
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.
