Business and government use your ABN information to verify who they are dealing with.
Once registered your ABN details are stored in the Australian Business Register (ABR). To make sure business information is accurate the Register is reviewed regularly.
You may be contacted by us to check that your ABN details are up to date or that you are still operating your business. If we find that your business is no longer operating your ABN may be cancelled.
Under the ABN Act 1999 all businesses are required to update their details within 28 days of becoming aware of changes.
If you think your details might be out of date you can update them by contacting us by phone or using AUSkey.
