When you apply for or update an ABN, the Australian Business Register asks for two addresses.
| Address | What it is | PO Box OK? |
|---|---|---|
| Business location | Where you actually operate the business | No, it should be physical |
| Address for service | Where you want mail and notices sent | Yes |
What’s public?
ABN Lookup shows the state and postcode of your main business location, not the full street address. So your home address isn’t published there. Where it does leak is everywhere else: invoices, quotes, your website and your Google profile.
Where a business address helps
- As your address for service, so business mail goes to us, not home.
- On invoices, your website and your email signature.
- As your business location only if that’s accurate for how you operate. That’s your call.
