Question: can tfn be 8 digits?
Answer: The TFN itself was either 8 or 9 digits, with a check digit. Individuals received a 9 digit TFN and non-individuals received an 8 digit TFN. ... However, as the 8 digit TFNs were becoming exhausted, all new taxpayers are issued 9 digit TFNs. The numbers now do not have any embedded meaning.
