ISIN Services

Request an ISIN

ASX is the National Numbering Agency (NNA) for Australia and a member of the Association of National Numbering Agencies (ANNA).

In its capacity as the NNA for Australia, ASX is responsible for the allocation of International Securities Identification Numbers (ISIN), Classification of Financial Instruments (CFI) codes and Financial Instrument Short Names (FISN) for Australian issued financial instruments.

ASX will allocate ISINs for securities of Australian issuers that are listed on ASX, debt securities issued in Austraclear, CHESS Depository Interests (CDI) and CHESS eligible securities of Australian issuers that are listed on other Australian financial markets. The ISIN will be allocated as part of our current services. It is not necessary to request an ISIN for these securities.

Requests for ISINs for foreign issued financial instruments should be made to the National Numbering Agency of the country where the issuer is registered or domiciled. Details of foreign National Numbering Agencies can be found on ANNA's Members List.

Requests for ISINs for OTC derivatives should be made to ANNA's Derivatives Service Bureau.

Globally, the CFI and FISN code will be allocated concurrently with the allocation of the ISIN.
