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.
