About the Australian Business Number (ABN)
The Australian Business Number (ABN) is a unique 11-digit identifier issued by the Australian Government to registered business entities operating in the country.
Our tool generates mathematically valid mock ABN numbers. The first digit receives a positional subtraction adjustment (-1) and the weights [10, 1, 3, 5, 7, 9, 11, 13, 15, 17, 19] are checked against Modulo 89.
