Australian Company Register Search (ASIC ACN Lookup)

Search the official Australian Company Register in bulk — 4.3 million+ companies incorporated in Australia and held by ASIC — by company-name keyword, by ACN (Australian Company Number) or by ABN. No API key, no login, no fragile page scraping: this actor reads the government open-data feed on data.gov.au directly and returns clean, structured JSON.

Give it a list of searches and it paginates the register for each one, so you can pull hundreds or thousands of matching companies in a single run.

What you can do with it

• Company lookup (KYB / due diligence) — enter an ACN or ABN and get the company's name, status (Registered / Deregistered / external administration), type, class and registration date, plus any former names on record.
• Lead & target lists by keyword — every registered company with "solar", "mining", "logistics", "consulting" in its name, with registration dates and state.
• Verify a company is active — confirm a company is currently Registered before signing, lending or onboarding, or spot strike-off / deregistration.
• Name-history checks — see a company's current name and its previous names, with the date the current name took effect.
• Market & competitor research — count and list companies in a niche or state.

Input

queries is a list. Any 9-digit number is treated as an ACN, any 11-digit number as an ABN (spaces and punctuation are ignored). Anything else is a full-text company-name search.

{
    "queries": ["solar", "000014675", "88000014675"],
    "maxResultsPerQuery": 50,
    "statusFilter": "all"
}

• queries — company-name keywords, ACNs and/or ABNs. Each is searched separately.
• maxResultsPerQuery — cap on rows returned per search (1–10000). The actor paginates automatically until it hits this number or runs out of matches.
• statusFilter — all, Registered (active only), or Deregistered only.

FAQ

Where does the data come from? The ASIC Company Dataset published as open data on data.gov.au (the Australian Government open-data portal), licensed Creative Commons Attribution 3.0 Australia. ASIC refreshes it regularly.

Is this the same as the Business Names Register / ABN Lookup? No — this is the Company register (companies identified by ACN), the companion to the Business Names register. Each row links to the official ABN Lookup pages for full entity details (entity type, GST status, etc.).

Do I need an API key or ABR GUID? No. This source is fully public.

Can I search by ACN or ABN? Yes — enter a 9-digit ACN or an 11-digit ABN and you get that company plus any former names on record. A name keyword runs a full-text search instead.

Is personal data included? No. This is company-level register data only — company names, ACNs/ABNs, statuses, types and dates. No individual/natural-person records.
