Trading Names and Business Names are two different things
Prior to 28th May 2012, entities did not have to register a business name, instead they could choose to carry our business activities under a trading name. Trading names were governed by old state and territory laws and are now effectively historical unregistered names used by entities for business purposes. However, with the introduction of the Australian Business Register, if businesses wanted to trade under a specific name, they were required to register it as a business name with the Australian Securities and Investments Commission (ASIC). This remains the case.
It is important to note that as of the 31st of October 2025 the Registrar will not publicly display trading names that were recorded in the ABR prior to the 28th of May 2012. As a result, we urge you to please check any linked business names and contact us should you still have trading names displayed on the ABN lookup.
