ABN (Australian Business Number)
The ABN is a unique 11 digit identifier issued to all entities registered in the Australian Business Register (ABR). It is used when dealing with government agencies (including the Australian Taxation Office) and other businesses.
An ABN can have a status of active or cancelled. A status of cancelled means the business has ceased trading. If an entity with an ABN has an associated ACN, ARBN or ARSN you can search ABN Lookup using that ACN, ARBN or ARSN.
See the Australian Business Register website for more information about ABNs.
