Australia Company Lookup: A Trading Name Is Not a Business Name

An Australia company lookup involves two authorities that hold different things. ASIC — the Australian Securities and Investments Commission — holds the company and business names registers, searched through ASIC Connect. The Australian Business Register (ABR) holds ABN information, and its public interface is ABN Lookup at abr.business.gov.au. Bulk downloads of ASIC registers are on data.gov.au. This guide covers a split that catches almost everyone, a reverse search, and a filing duty with a deadline. If you need the Australian population rather than one company at a time, the Australia company directory covers the same registered entities with industry, size and contact breakdowns attached, and the Australia business database is the same file described as a dataset.

Australia company lookup: the short version

  • Trading names are not registered business names and do not appear on ASIC's business names register. ASIC says so on that register's own page and sends you to ABN Lookup instead.
  • ASIC's register supports a reverse search: search a person or organisation to see any business names they hold.
  • An ABN must be updated within 28 days if details change or the business stops operating, and may be cancelled if records show the holder is no longer carrying on a business.
  • Basic company information is free; more can be bought, and ASIC's registers are also downloadable from data.gov.au.

Two registers, two agencies, two things called a name

The single most expensive misunderstanding about Australian company data is stated plainly by ASIC, on the page where it matters:

"Trading names are not registered business names and do not appear on the business names register. If you want to search for a trading name, use the Australian business register's ABN Lookup service."

The failure mode is what makes this the page. Searching ASIC for a trading name and finding nothing is not evidence the business is unregistered. It is the wrong register. And it fails silently — an empty result looks identical whether the name does not exist or simply is not the kind of name that register holds.

So: ASIC holds companies and registered business names. The ABR holds ABNs and is searched through ABN Lookup. Two authorities, two registers, and two different things that a reader would call "a name".

One caveat, and it matters enough to state rather than bury. ASIC's instruction sends you to ABN Lookup for trading names. Where trading names appear on ABN Lookup, and under what conditions, is a position that has been subject to change — and this page does not establish the current one. Check ABN Lookup itself before relying on it as the trading-name route. That is worth doing precisely because the advice above is ASIC's and points outside ASIC: a rule about another agency's service can go out of date on the page that references it. AUSTRALIA_REPORT.md flags it as the first thing to verify.

ASIC's business names register works in both directions, and names the modes exactly.

Forward — from name to holder: "You can search for a business name to find out the person or organisation that holds it. […] Under 'Search business names register', select 'Search within: Business names index' and enter the business name you want to search for."

Reverse — from person to names: "You can search the name of a person or organisation (such as a company), to see any business names they hold. […] Under 'Search business names register', select 'Search within: Business names holder – person' or 'Business names holder – organisation'. Enter the name, ABN or ACN you want to search for."

Three modes, then: Business names index, Business names holder – person, Business names holder – organisation — with the holder searches accepting a name, ABN or ACN.

Several registers in this programme let you start from a person, and each returns something different. The Croatia company lookup guide covers one that publishes the entities a person is or was registered in, with functions and periods. The Slovenia company lookup guide covers one that offers a search across four named roles. The Israel company lookup guide covers one that sells information on office-holders serving now or in the past. Australia's returns the business names they hold.

Four registers, four answers to "start from a person", and this page ranks none of them. They return different objects — roles, offices, names — and knowing which one you get is the difference between a useful query and a misleading one.

What an Australian company register entry contains

A self-contained summary. Australia's company and business names registers are held by ASIC, the Australian Securities and Investments Commission, and searched through ASIC Connect; the Australian Business Register holds ABN information, with ABN Lookup at abr.business.gov.au as its public interface. ASIC states that trading names are not registered business names and do not appear on the business names register, and directs those searching for a trading name to ABN Lookup. The business names register can be searched from name to holder, by selecting Search within: Business names index, and from holder to names, by selecting Business names holder – person or Business names holder – organisation and entering a name, ABN or ACN. ASIC's register index covers, among others, companies and some other organisation types, with a check of whether a name is available for registration; documents lodged with ASIC; where a financial adviser has worked, their qualifications and training, and the products they can advise on; people and entities who have paid infringement notices issued by ASIC; court enforceable undertakings ASIC has accepted; certificates of transfer for licensed trustee companies; and fundraising documents lodged with ASIC. Basic information about a company or organisation is available for free, and more information can be bought online. Data from the ASIC business registers that ASIC makes available for download can be accessed through data.gov.au. ABN Lookup gives free access to public ABN information from the Australian Business Register, no login is needed, and ABN Lookup tools are offered for multiple searches. An ABN must be updated within 28 days if details change or the business stops operating, and an ABN may be cancelled if records show the holder is no longer carrying on a business. This summary does not describe the fields an ASIC extract returns, because none was established from ASIC's own pages on the date shown.

The 28-day rule

The most practically useful fact on this page is about currency, and it is the ABR's own:

"You must update your ABN within 28 days if your details change or your business stops operating. Your ABN may be cancelled if records show you are no longer carrying on a business."

Two things follow for anyone using Australian data.

The register's currency rests on a filing duty with a deadline. Not on a periodic refresh, not on an audit, not on cross-checking against another source — on the holder's obligation to update within 28 days. That is a stated maximum lag between a change and the record reflecting it, which is a rare thing to have in writing.

And cancellation follows from records showing the business has stopped, rather than from a declaration by the holder. An ABN can lapse because of what the records indicate.

This page does not estimate compliance with the 28-day rule, or how stale the register is in practice. Neither was sourced, and both would be guesses dressed as findings.

An unusually broad register index

Worth listing because it is wider than most readers expect from a corporate regulator. ASIC's register index covers, among others:

  • companies and some other organisation types, with a check of whether a name is available for registration
  • documents lodged with ASIC
  • where a financial adviser has worked, their qualifications and training, and the products they can advise on
  • people and entities who have paid infringement notices issued by ASIC
  • court enforceable undertakings ASIC has accepted
  • certificates of transfer for licensed trustee companies
  • fundraising documents lodged with ASIC

Listed as ASIC lists them. None is described here — the index names them and does not explain what each contains.

Where an Australia lookup stops

On cost, ASIC's own wording: "Basic information about the company or organisation is available for free. […] If you need more information than what you can get for free, you can buy more information online." No figures appear on this page.

On ABN Lookup: "ABN Lookup gives you free access to public Australian Business Number (ABN) information from the Australian Business Register. […] No login is needed. Doing multiple searches? Use ABN Lookup tools to help you." Free, no login, and tools offered for multiple searches — what those tools are is not described here.

On bulk: ASIC states you can "Access data from the ASIC business registers that ASIC makes available for download through data.gov.au." The downloads exist. Their licence and refresh cadence are not stated on this page, because neither was sourced.

This page describes no field of an ASIC extract. AUSTRALIA_REPORT.md records that alongside the trading-name caveat and the question of whether the ABR runs a public API.

Where the question is a population rather than a company, a firmographic directory covers the same registered entities with classification, size and contact data attached and queryable as a set; the Oceania company directory breaks the regional file down by market.

Data quality pitfalls to avoid in Australia

Searching ASIC for a trading name. They are not registered business names and do not appear on that register; ASIC directs trading-name searches to ABN Lookup.

Reading an empty ASIC result as non-registration. It may be the wrong register, and the failure is silent.

Assuming the trading-name route is stable. Where trading names appear on ABN Lookup has been subject to change, and this page does not establish the current position.

Treating ASIC and the ABR as one system. They are separate authorities holding different things, and nothing here establishes how or whether their records can be joined.

Assuming data currency without the filing duty. The register's currency rests on the holder's obligation to update within 28 days.

Reading a cancelled ABN as a declaration. An ABN may be cancelled if records show the holder is no longer carrying on a business.

A repeatable Australia company lookup workflow

  1. Decide which kind of name you have before choosing a register.
  2. Search ASIC for companies and registered business names; use ABN Lookup for trading names.
  3. Verify the current trading-name position on ABN Lookup rather than assuming it.
  4. Use the holder searches — person or organisation — when starting from an entity, with name, ABN or ACN.
  5. Date every observation against the 28-day update duty rather than assuming real-time accuracy.
  6. Take bulk from data.gov.au, and confirm its licence and cadence independently.

Frequently asked questions

Why can't I find a trading name on ASIC's register?

Because trading names are not registered business names and do not appear on the business names register. ASIC directs trading-name searches to the Australian Business Register's ABN Lookup service.

Is ABN Lookup the reliable route for trading names?

It is the route ASIC names. Where trading names appear there, and under what conditions, has been subject to change, and this page does not establish the current position — check ABN Lookup itself.

Can I search by person?

Yes. Search the name of a person or organisation to see any business names they hold, using Business names holder – person or Business names holder – organisation, entering a name, ABN or ACN.

How current is Australian register data?

An ABN must be updated within 28 days if details change or the business stops operating. This page does not estimate compliance with that duty.

Can an ABN be cancelled without the holder asking?

The ABR states an ABN may be cancelled if records show the holder is no longer carrying on a business.

Is searching free?

Basic information about a company or organisation is available for free, and more can be bought online. ABN Lookup gives free access to public ABN information, with no login needed.

Can I download the registers?

ASIC makes data from its business registers available for download through data.gov.au. The licence and refresh cadence are not stated here.

Every sentence quoted above is the publisher's own wording, read on the date shown. No amount appears anywhere in this page's prose.

This page does not state when unregistered trading names stopped appearing in public ABN searches, whether the ABR runs a documented public API, or the licence and refresh cadence of the ASIC datasets on data.gov.au. All three come from commercial sources. AUSTRALIA_REPORT.md lists them in priority order and flags the trading-name change first, because ASIC's own advice on this page points at ABN Lookup and a change there would leave that advice with a hole in it.

The readings that are InfobelPRO's rather than the authorities': that searching ASIC for a trading name and finding nothing is not evidence of non-registration but of the wrong register, and that the failure is silent; and that the register's currency rests on a filing duty with a deadline rather than on any refresh or audit, so every observation should be dated against it. Those are ours. The four-register comparison on starting from a person notes that each returns a different object and ranks none of them.
