Update your ABN details

It’s easy to forget to update your Australian business number (ABN) details during the day-to-day demands of running a business. But you must keep your contact details up to date because:

  • Emergency services and government agencies use ABN details to help identify and contact businesses during emergencies or times of crisis (For example bushfires and COVID-19). If your details are out-of-date you risk missing important assistance, updates or access to grants.
  • Keeping your information up to date is also important as other businesses and government agencies use the ABN to identify whether a business is genuine.

We recommend ensuring your contact details are up to date, including:

  • physical location
  • postal address
  • email
  • phone number.

You can update your ABN details online through ABR online services using myGovID and RAM.
