Confidence justification

Medium confidence: eight-digit numbers are very common. Slovenian tax keywords like 'davčna številka' or 'FURS' are needed for reliable detection. Added context gating and exclusion rules improve precision and reduce incidental matches.

Known false positives

• Generic numeric sequences in non-tax contexts such as reference numbers or account identifiers Mitigation: Require corroborative evidence keywords within the proximity window to distinguish tax identifiers from general numeric data.
• Numbers from other identification schemes with similar digit patterns Mitigation: Layer with jurisdiction-specific detection to prioritise matches in tax-related documents and cross-reference with other identifier types.
