ABN Lookup is a free public view of the Australian Business Register (ABR) that provides access to publicly available information that businesses supply when registering for an Australian Business Number (ABN). This Android application offers the convenience of accessing the publicly available information about a business on the go. Users can search for an ABN, ACN, ARBN, ARSN, or ARFN and get information such as the business name, status, postcode of the main business location, GST registration, DGR registration, and more. However, the app does not hold non-public ABR data such as detailed contact information or industry codes. It is important to note that the information provided on the app is dependent on the business entities updating their details when they change, so it may not be completely accurate or up-to-date. If you have doubts over the currency of information provided on the ABN Lookup app, it is recommended to verify the information from other sources.
