Existing six-digit IINs will be converted into a block of a hundred eight-digit IINs.The maximum will continue to be 19 digits in length. Issuers with eight-digit IINs will be required to issue a minimum PAN length of ten digits.

The Registration Authority (RA) will commence assigning eight-digit IINs to any institution applying for a single IIN or block of IINs.Major changes included in the revised version of this standard will mean that, as of the publication date:

The draft of this revised standard has just been approved by ISO members and is expected to be published in early 2017. The PAN will continue to remain a variable length, ranging from 10 to 19 digits. Therefore, ISO/IEC 7812-1 is being revised to expand the IIN to an eight-digit numeric value from the current six digits. The PAN is of variable length, ranging from 8 to 19 digits.ĭue to the increasing number of card issuers, there is expected to be a shortage in the available supply of IINs. The standard also defines the Primary Account Number (PAN), a number which is used to identify an individual account holder. Within the current version of ISO/IEC 7812-1, an IIN is defined as a fixed-length numeric of six digits. The IIN structure is defined within ISO/IEC 7812-1, Identification cards – Identification of issuers – Part 1: Numbering system, developed by the ISO/IEC joint technical committee JTC 1, subcommittee SC 17, Cards and personal identification.
