Sweden Driver's License Number
Detects Sweden driver's license number patterns. 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
12345-1234— Too few digits before hyphen (5 instead of 6)123456-12345— Too many digits after hyphen (5 instead of 4)template example placeholder record identifier— Template/sample context should be excluded even when anchor words are present
Known false positives
- Swedish personnummer (personal identity number) shares a similar format, making it difficult to distinguish between the two by pattern alone. Mitigation: Require corroborative evidence keywords specific to driver's license context within the proximity window.
