Test Cases

When to use this pattern

This pattern is drawn from the Identity & PII > Driver's License Numbers category and carries a ReDoS-safe certification. That matters for Go developers because Go's RE2 engine is inherently safe from catastrophic backtracking, but this pattern has been additionally verified for correctness. RegexVault audits patterns against known backtracking attack vectors, ensuring you have the necessary context before using this regex in a high-stakes production environment.

Technical Notes

State formats: NSW (6 digits), VIC (1 letter + 8 digits), QLD (8-9 digits), WA (7 digits), SA (6 digits + 1 letter), TAS (6-8 digits), ACT (10 digits), NT (10 digits). Use state-aware validation when the state is known.
