How do I get an ABN?

The Australian Business Number (ABN) is a FREE unique 11-digit identifier issued by the Australian Tax Office here: https://www.abr.gov.au/business-super-funds-charities/applying-abn

Those affected by DV can apply for a suppression order (to not display their address publicly online) from the ABR Registrar who is Chris Jordan.

Chris is the Commissioner of Taxation and Registrar of the Australian Business Registry Services his email is Chris.Jordan@ato.gov.au

Executive Assistants at the Commissioner Level who over-see mailboxes are normally pretty swift to act on these types of safety-related suppression requests.
