The ATO advises that the Australian Business Register has simplified the proof of identity documentation requirements for non-resident Australian business number (ABN) applicants.
If support is required during the application process, the ATO's non-resident team can be contacted directly on 1300 146 094.
This is a general enquiry phone number and has a variety of prompts. Callers will need to wait until they hear instructions to enter the three digit call-back code, when they need to enter 118 and '#'.
The correct team can then assist.
