In 2004, ASX appointed APIR Systems Limited as a sub-numbering agency for the allocation of International Securities Identification Numbers (ISINs). APIR allocates ISINs to Collective Investment Vehicle products which are:
- products of issuers domiciled in Australia
- not traded on the ASX or any other stock exchange
- products for which APIR-assigned Product APIR Codes or SPIN are recognised by the Financial Services Council (FSC) as the industry standard identifier in Australia.
ISINs are used internationally for product identification purposes.
