Search the business name register before choosing a name

How to search ASIC's business names register and ABN Lookup to check whether a preferred business name is already registered or cancelled.

Why the register search comes first

Once you have settled on a name for a sole trader operation, a partnership or a company trading style, the register search is the fastest way to find out whether that name is already taken and who is using it. ASIC's business names register is public, it holds information on both registered and cancelled business names, and ASIC states that anyone can search it to find out more about a business name or to find out who holds one.

Running the search before you print signage, buy a domain or register anything means the decision you are making is based on the official record rather than on what a web search suggests. It will not tell you everything — a name can be free on the register and still carry other risks — but it answers the first and most basic question: is this name already in use.

What the business names register actually shows you

According to ASIC, you can search the register for information on registered and cancelled business names. That distinction matters more than it first appears. A name that appears in results is not automatically unavailable to you; it depends on the status attached to the record.

Read the status, not just the name. A close match that is cancelled is a different situation from a close match that is registered and held by an active business in your industry.

How to search the register

ASIC's business names search sits within its register search service. The mechanics, as set out by ASIC, are straightforward:

  1. Go to ASIC's business names register search (ASIC Connect, Search ASIC Registers).
  2. Under "Search business names register", select "Search within: Business names index" and enter the business name you want to search for.
  3. Review the results, noting the status of each record and who holds it.

ASIC also provides two holder-based searches. Under the same "Search business names register" heading, you can select "Business names holder – person" or "Business names holder – organisation". These are useful in two situations: when you want to see what else a particular person or organisation already holds, and when you are researching a name that a competitor uses.

ASIC publishes supporting pages explaining more about searching information on business names, on business name holders (separately for organisations and for persons), and about checking business name availability. If a result is ambiguous, those pages are the place to check what the field means before you act on it.

Using "Check business name availability"

ASIC offers a Check Name Availability function alongside the register search. Treat the two as a sequence rather than alternatives: search the register to understand what exists, then use the availability check on a shortlist of names you are seriously considering.

A practical interpretation — and the reason to keep the register search in the loop — is that an availability result is a signal about the register, not a guarantee about anything else. Confirm the outcome against the register record before you commit.

Trading names belong to a different search

If what you are trying to find is a trading name, ASIC directs you to the Australian Business Register rather than its own register. ABN Lookup, run by the Australian Business Register, gives free access to public Australian Business Number (ABN) information.

Through ABN Lookup you can:

The ABR describes the tool as being used by the public to check a business before buying, and by accountants, tax agents and advisers to verify business information. That second point is worth borrowing: the same check that protects a purchaser protects you when you are confirming that a name you like belongs to a genuinely operating business.

To apply for, update or cancel an ABN, the ABR is the relevant destination — searching ABN Lookup is read-only and does not change any registration.

Which search answers which question

Your question Where to look What it tells you
Is this exact name already registered? ASIC business names register — Business names index Registered and cancelled records matching the name
Who holds this name? ASIC business names register — holder search (person or organisation) The holder behind a name, and other names they hold
Is my shortlisted name available? ASIC Check Name Availability Whether the register shows the name as available
Is this a trading name with a live ABN? ABN Lookup (Australian Business Register) ABN status (active or cancelled), business type, GST status

Checklist before you commit to a name

Questions you should verify yourself

The register search answers one specific question well. These adjacent questions are worth confirming with the responsible source rather than assuming:

Next steps

  1. Write down three to five candidate names, in priority order.
  2. Search each one in the ASIC business names index and note the status of any match.
  3. Run holder searches on the closest matches.
  4. Cross-check your leading candidate in ABN Lookup.
  5. Run Check Name Availability on the surviving shortlist.
  6. Keep a dated note of what you searched and what you found.
  7. Complete registration through the official channel, confirming the current process with ASIC rather than relying on third-party summaries.

If every candidate collides with a registered name, the fix is usually a distinguishing element — a location, a descriptor or a different word order — rather than abandoning the idea. Search again after you adjust; the register is the only place that confirms whether the change worked.
