    How do I find a company's registration number in Australia?

    Search the company's name on ABR at https://abr.business.gov.au. The result page shows its registration number — the same identifier that appears on invoices, contracts, and government filings.

    Step-by-step

    1. 1

      Open ABR

      Navigate to https://abr.business.gov.au.

      https://abr.business.gov.au
    2. 2

      Search by company name

      Type the exact trading or legal name. Partial matches usually work; add the city if the name is common.

    3. 3

      Copy the registration number

      The registration number is displayed at the top of the entity profile. It is the authoritative ID for cross-referencing.

    4. 4

      Confirm it's the right entity

      Check the registered address and incorporation date to be sure you have the correct legal entity, especially for groups with similarly named subsidiaries.

    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.

    Check current access and document options on the official ASIC / Australian Business Register site. For search limitations and missing-result guidance, see the Australia registry guide.

    Frequently asked questions

    Where is a Australia company's registration number published?

    Look for the identifier on the entity's record or available extract in ABR (https://abr.business.gov.au). Compare it with the counterparty's documentation; publication requirements and identifier labels vary by jurisdiction.

    Is looking up a Australia registration number free?

    LemReveal's basic lookup is free. Check ABR's current access rules: an official portal can require an account, charge for searches or restrict particular documents.

    Is the Australia company register free to search?

    Yes. Basic company lookups on the ASIC / Australian Business Register are free — you can search by company name or registration number, view legal status, registered address and (usually) directors at no cost. Some jurisdictions charge a small fee only for downloading full filed documents.

    What is the official Australia business registry?

    The ASIC / Australian Business Register is the official public register of companies incorporated in Australia. It is operated by the government and is the primary source cited on this page — https://abr.business.gov.au.

    Where do I find a Australia company's registration number?

    Every registered Australia entity has a unique registration number issued at incorporation. It appears on invoices, contracts, the company's website footer (often in a "legal" section), and prominently on its ASIC / Australian Business Register record.

    Is a Australia registration number the same as a VAT number?

    No. The registration number is the identifier issued by the ASIC / Australian Business Register when the company was formed. The VAT number is a separate tax identifier issued (only if the company is VAT-registered) by the national tax authority. Many small companies have a registration number but no VAT number.
