The AustralianTFNGen Generator generates random Australian Tax File Numbers. The tax file number (TFN) is a personal reference number in the tax and super systems. The TFN is an important part of your tax and super records as well as your identity, so keep it secure.


A TFN is assigned for life even if a person changes their name, change jobs, move interstate or go overseas. The synthetically generated TFNs will pass a TFN validity check.


The following parameters may be configured for the AustralianTFNGen Generator. Items with an asterisk* are required.  

  • Randomize* – Select true for random values, or false for alphabetical order.

  • Seed - Using the seed will ensure that the same random data is generated each time data is generated.
