EU Driver's License Number
Detects EU driver's license number patterns across all EU member states. This pattern is based on a Microsoft Purview built-in sensitive information type. Users already running Purview may prefer to enable the built-in SIT directly, or use this version as a starting point for customisation.

Should not match
ABCD— Too few characters (4 instead of minimum 5)A1B2C3D4E5F6G7H8I9J0K— Too many characters (21 instead of maximum 20)template example placeholder record identifier— Template/sample context should be excluded even when anchor words are present
Known false positives
- Generic alphanumeric sequences matching the broad EU driver's license format appearing in unrelated contexts such as product codes, serial numbers, or reference identifiers. Mitigation: Require corroborative evidence keywords within the proximity window to confirm driver's license context.
