ABN Lookup contains the publicly available information provided by businesses when they register for an
Australian Business Number (ABN).
The ABN Lookup website and services are hosted by the Department of Industry and Science.
All data available through ABN Lookup is owned and managed by the Australian Business Register (ABR)
within the Australian Taxation Office (ATO).
Importantly, new registrations and updates must first appear in the ABR before they can appear in ABN Lookup.
