  • More than just a business number

    Updating your Australian business number (ABN) details can be easily overlooked during the day-to-day demands of running a business. It is important to keep your contact details up to date for a couple of reasons.

    In times of natural disaster, key Government agencies use ABN data to identify business in affected areas that might need help or support during and after the event. If your ABN details are out of date you risk missing out on important assistance, updates or opportunities such as grants.

    Keeping your information up to date is also important as other businesses and Government agencies use the ABN to identify that you are in fact a genuine business.

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

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

    If you are no longer in business you should cancel your ABN. This can be done online and takes effect immediately.
