Australian Driver's Licence Number

Discovery-only compatibility coverage for Australian driver's licence number candidates across all states and territories. The stable au-motor-vehicle-permit slug is retained for catalogue, collection, workbook, and package compatibility. State and territory enforcement belongs to the eight au-*-driver-licence-number SITs. Microsoft Purview tenants can instead select the free built-in Australia Driver's License Number entity (1cbbc8f5-9216-4392-9eb5-5ac2298d1356); this compatibility pattern is not a custom clone of that built-in.

Type: regex
Engine: universal
Confidence: low
Confidence justification: Low confidence: this national compatibility detector intentionally inventories broad candidates only. Use a state/territory SIT at confidence 75 or 85, or Microsoft's built-in entity, for policy enforcement.
Detection quality: Mixed

Regulations: AML/CTF Act (Cth), NDB Scheme (Cth), Privacy Act 1988 (Cth)
Frameworks: ISO 27001
Data categories: pii, government-id
Scope: wide
Risk rating: 5
Platform compatibility: Purview: Compatible, GCP DLP: Unsupported, Macie: Unsupported, Zscaler: Compatible, Palo Alto: Unsupported, Netskope: Unsupported

Known false positives

Account, invoice, order, telephone, and other numeric identifiers with six to ten digits. Mitigation: Treat the stable national slug as discovery-only and enforce with the matching regional SIT.
Policy and public guidance discussing licence-number formats without a populated value. Mitigation: Require a regional labelled-number primary and state authority evidence at higher confidence.
Australian mobile telephone numbers can satisfy a ten-digit candidate shape. Mitigation: Exclude AU mobile-number shapes from the discovery tier.
