ISO/IEC 7812-2:2017 defines how organisations apply for and register Issuer Identification Numbers. It complements Part 1's numbering structure with an allocation process, providing an administration framework so issuer identifiers are assigned rather than chosen by each issuer.
TL;DR:
- ISO/IEC 7812-2:2017 governs application and registration of IINs.
- It complements the numbering system defined in Part 1.
- Edition 5 remains published after confirmation in 2022.
Summary
Registration scope
ISO/IEC 7812-2:2017 specifies application and registration procedures for issuer identification numbers issued under ISO/IEC 7812-1. Its focus is administering identifiers rather than defining a complete card-payment scheme.
Relationship to Part 1
Part 1 supplies the issuer-numbering system and formats; Part 2 governs how the associated IINs are applied for and registered. Both roles matter when distinguishing a validly allocated identifier from a merely plausible card-number format.
Administrative boundary
IIN registration does not by itself establish a card product’s acceptance, payment-scheme membership or security certification. Those questions belong to the relevant issuing and network arrangements.
Edition and status
ISO lists edition 5, published in January 2017 and confirmed in 2022. The publication remains current and published; undated possible withdrawal steps in the lifecycle diagram are not completed events. Detailed application requirements require the applicable standard and registration-authority guidance.
