What is an ABN?
An Australian Business Number (ABN) is a unique 11-digit identifier issued by the Australian Business Register (ABR). Every business operating in Australia should have an ABN. It's used for tax purposes, invoicing, and interacting with government agencies.
Why Look Up an ABN?
- Verify a supplier: Confirm they're a legitimate registered business before paying
- Check GST registration: Know whether to expect a tax invoice with GST
- Avoid withholding tax: If a supplier can't provide a valid ABN, you may need to withhold 47% from payments
