ACN (Australian Company Number)

An Australian Company Number (usually shortened to ACN) is a unique nine-character number issued by the Australian Securities and Investments Commission (ASIC) to every company registered under the Commonwealth Corporations Act 2001 as an identifier. The number is usually printed in three groups of three digits.

If an entity with an ACN has an associated ABN, ARBN or ARSN you can search ABN Lookup using that ABN, ARBN or ARSN.

Example:

000 000 123

See the Australian Securities and Investments Commission website for more information about the ACN.
