A trading name was a name used by an entity or person to trade under, without it being registered as a business name.
Trading names were collected prior to 28 May 2012 by the Australian Taxation Office (ATO). They will be displayed on the Australian Business Register (ABR) until 31 October 2018.
You are still able to maintain the details of your trading name with the Australian Taxation Office for taxation purposes. However any updates will not be displayed on the ABR’s ABN lookup service.
