Update ABN details
The Australian Business Register (ABR)
maintains the information available through ABN Lookup. For options on how to
update your ABN details please visit the ABR website.
Only when the details have been updated on the ABR will the changes appear on ABN Lookup.
You are required by law to ensure your ABN details are kept up-to-date. You must notify the ABR of changes to your business details within 28 days.
As ABN Lookup does not have access to update ABN details please contact the ABR if you require further assistance.
