ABN most commonly stands for Australian Business Number. It is a unique 11-digit identifier issued by the Australian Business Register (ABR), operated by the Australian Taxation Office (ATO). The ABN is used by entities carrying on a business in Australia to identify themselves for tax and business purposes, such as invoicing, claiming GST credits, and interacting with government agencies.

Other less common meanings of ABN include Airborne and Advance Beneficiary Notice, but in general business or Australian context, ABN refers to Australian Business Number.
