Australian Business Number

To register a business name, you will need to have an Australian Business Number (ABN) or be in the process of applying for one with the Australian Business Register (ABR).

Using the ABN ensures greater consistency between the ABR and ASIC’s business names register and avoids an additional identification number for your business name.

When you apply for an ABN online through the ABR, you can link straight to ASIC Connect to register your business name online. This new ABR service allows business owners to apply for an ABN and register a business name in a single transaction.

Apply for an ABN


You do not need an ABN to register a business name if you:

  • operate solely in the Christmas Islands or Cocos (Keeling) Islands, and
  • you are not entitled to an ABN under the A New Tax System (Australian Business Number) Act 1999.

However, you must provide us with information about the type of entity that will hold the business name (i.e. individual, company, partnership, joint venture or other organisation).
