“From November 2018, trading names will be removed from the ABN Lookup. The ABN Lookup contains a list of all Australian Business Numbers (ABNs) and any associated business names.
If you want to trade under a specific name, you’ll need to register it as a business name with the Australian Securities and Investments Commission (ASIC).
You don’t need to register a business name if you trade under your own name (‘John Smith’), but you’ll need to have a business name if it’s anything else (‘John Smith Plumbing’).”
