We are the ISO recognised Numbering Authority for the UK and overseas countries for the issuance of Registered identifier number (RID) - part of the application identifier under  ISO/IEC 7816-5.

The RID is part of an application identifier (AID) which is structured according to ISO/IEC 7816-5 and consists of two parts:

  1. The RID - unique to an application provider and assigned according to ISO/IEC 7816-5.
  2. An optional field - assigned by the application provider known as a proprietary application identifier extension (PIX), used to identify different applications or products.

You will need this type of RID if you provide an application in an Integrated Circuit Card.
