• What you need for your client's ABN application

    When applying for an Australian business number (ABN) online on behalf of your client it is important you provide accurate details about their business or organisation to avoid delays in processing the application.

    The proof of identity (POI) information you provide will be validated against other sources; for example, Australian Taxation Office (ATO) tax records and the Australian Securities and Investments Commission (ASIC).

    If these details do not match, the application will be delayed or in some instances refused. You will receive a reference number after the application is submitted. You should quote this reference number when you send us your documents or if you need to contact us.

    This reference number will help us identify your application. If you lose this reference number we may not be able to help you, and you may need to lodge a new application.

    If your client or their associates are non-residents of Australia you will need to send:

    You should send these documents by the due date specified at the end of the application.

    Box Hill VIC 3128 AUSTRALIA

    Note: The ABN application will be refused if you do not provide these documents within 43 days of submitting the application. If the ABN application is refused you will be advised by letter.
