About the Tax File Number (TFN)
The Tax File Number (TFN) is a unique 9-digit identifier issued by the Australian Taxation Office (ATO) to individuals for tax and superannuation administration.
This tool generates mathematically valid mock TFN codes. The calculation is based on positional weights [1, 4, 3, 7, 5, 8, 6, 9, 10] from left to right and Modulo 11 zero-remainder check.
