What is ABR?
The ABR (Australian Business Register) is the free public database of every Australian Business Number (ABN). Search at abr.business.gov.au — no signup — for legal name, ABN status, GST registration, and entity type.
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.

Frequently asked questions
How do I do an ABN lookup?
Go to abr.business.gov.au and enter the ABN, ACN, or business name. Results are free and include current legal name, ABN status, GST registration, and the state of the main business location.
What is the difference between ABN and ACN?
The ACN (Australian Company Number, 9 digits) is issued by ASIC on incorporation. The ABN (Australian Business Number, 11 digits) is issued by the ATO for tax purposes. Every registered company has both; sole traders and trusts only have an ABN.
Is ABN lookup free?
Yes. The ABR public search is free with no rate limit for interactive queries and no account required.
