The ABN Lookup provides online access to the Australian Business Register for publicly available information supplied by businesses when they register for an Australian Business Number (ABN).
The register shows the GST registration status of the entity (including sole traders, companies, trusts and other entities) and the ABN number as well as current trading names.
The register can be searched either by name, ABN or ACN for corporate entities.
