Why Australian Businesses Need ABN Lookup

Verifying an ABN before engaging a supplier, contractor, or tradie is one of the most important due-diligence steps an Australian business can take. An ABN lookup through the Australian Business Register (ABR) tells you instantly whether the business is legitimate, whether it is registered for GST, and what type of entity you are dealing with.

For small businesses hiring tradies, an ABN lookup helps you confirm that the person quoting on your job is a real registered entity and not operating as an unlicensed sole trader. For larger businesses managing supplier relationships, it is a quick sanity check before raising a purchase order or processing a payment.

GST registration status is another critical piece of information. Businesses with a turnover above $75,000 are required to register for GST in Australia. If you receive a tax invoice that includes GST but the business is not registered, you may not be able to claim that GST as an input tax credit. A quick ABN lookup confirms GST registration before you file your BAS.

This tool uses the official ABR JSONP API, the same data source as the ATO and Australian Business Register. Results include entity name, ABN status, entity type (sole trader, company, partnership, trust), GST registration, and main business location.
