ABN Lookup is the public view of the Australian Business Register (ABR). It provides access to publicly available information supplied by businesses when they register for an Australian Business Number (ABN).
The ABN Lookup tools may assist with multiple searches.
Update your ABN details
It is essential your ABN details are kept up-to-date. Many agencies across all levels of government rely on ABN information to target and provide important community services.
Tell us within 28 days if your business operation ceases or if your details change. Your ABN may be cancelled if information shows you are no longer carrying on a business.
To update your ABN details go to abr.gov.au .
Trading names are being retired
From November 2018, ABN Lookup will cease displaying all trading names and only display registered business names. If you wish to operate under a different name to your legal/entity name, you will need to register your business name with the Australian Securities and Investments Commission.
