Under the 2026 Privacy Act, Tax File Numbers (TFNs) require the highest level of protection. Manually scrubbing TFNs is prone to error and expensive.
The DCE Advantage
Our engine uses lookahead regex patterns to detect TFNs regardless of formatting (hyphens, spaces, or raw digits) while preventing collisions with Medicare numbers.
Input: "My TFN is 123-456-789"
Redacted: "My TFN is [REDACTED TFN]"
