System Maintenance

We are doing planned system maintenance from Thursday 19 September 2024 to Friday 20 September 2024 between 11:30pm and 7:00am (AEST). During this time, the ABN refresh service will be unavailable. Users may experience delays with their ABN's appearing on the Lookup services.

We are updating our IP address on Thursday, 26 September 2024.

The new IP addresses are:

ABN Lookup 192.199.33.8
Superfund Lookup 192.199.33.10

Update your whitelist to include these new IP addresses. We recommend using our full web addresses https://abr.business.gov.au and/or https://superfundlookup.gov.au when accessing our services. Accessing by other names or by IP address will be blocked and disabled in the near future.
