What is ACN?
The ACN is Australia's 9-digit identifier for every ASIC-registered company. Search at asic.gov.au to verify the ACN, current officeholders, and share structure; basic results are free, official extracts carry fees.
Australia: choosing and checking the right record
- Choose the correct source
- Use ABN Lookup for ABN status, entity name and GST information. Use ASIC for company and business-name registrations and company extracts. These services answer different questions; an ABN entry is not a company extract.
- Confirm the entity
- An ABN has 11 digits; an ACN has nine. Compare the legal entity name rather than just a business name. ABNs can identify sole traders and other non-company entities, so do not assume every result has directors.
- When the search returns nothing
- Try the exact ABN or ACN before a broad name search, then check historical names and cancellation dates. If you need director details, check ASIC's available extracts rather than expecting ABN Lookup to provide them.
- What the record cannot establish
- Public ABN information does not establish solvency, beneficial ownership or a full street address. GST registration and ABN status are distinct fields. ASIC documents can require payment; check the official terms before ordering.
Check current access and document options on the official ASIC / Australian Business Register site. Keep the exact entity identifier, source URL and retrieval date with your evidence. A LemReveal record PDF is not a government-certified extract.

The ACN system is run by ASIC (Australian Securities and Investments Commission). Every Pty Ltd, Ltd, and public company holds an ACN, distinct from the tax-issued ABN. ASIC's records are the authoritative source for share structure and directorships.
