  • Is your organisation contactable in an emergency?

    Updating your Australian business number (ABN) details might be the last thing on your mind but it is important to keep your contact details up to date, especially as the risk of natural disasters like bushfire and storms increases at this time of year. 

    During times of emergency or natural disaster, your ABN details are used by emergency services and government agencies to help identify businesses in affected areas that might need help or support. If your ABN details are out of date you risk missing out on important assistance, updates or opportunities such as grants. 

    To make sure you don’t miss out on receiving important information, update your ABN details such as: 

    • authorised contacts 
    • your organisation’s physical location (not your tax agent's address) 
    • postal address 
    • email address 
    • phone number. 

    In addition to the above, from late December, you’ll also be able to add 4 extra business activities (ANZSIC codes) to your ABN when updating your details. This is in addition to the main business activity that is currently captured. See Changes to ABN details for more information.External Link

    You must update your details within 28 days of becoming aware of changes. The Registrar is undertaking regular activities to removed ceased businesses from the register.

    If your organisation is no longer operating, cancel your ABN so you aren't contacted unnecessarily. You can cancel your ABN online using your myGovID. Your myGovID needs to be linked to your ABN using Relationship Authorisation Manager (RAM). All changes you make online to your ABN will take effect immediately.

    For examples of how ABN details are used during a disaster or emergency, visit the Australian Business Register (ABR) website.
