Confidence justification

Medium confidence: the 2-3-8 digit grouping pattern provides some structure. Bank-related keywords in Hebrew or English improve detection accuracy. Context label evidence plus explicit template/example exclusion improves precision for high-risk identifiers. Added context gating and exclusion rules improve precision and reduce incidental matches.

• 12-345-123456789 — 9 digits in account section, too long
• sample template placeholder number 123456789 — Template/sample context should be excluded even when numeric-like values appear

Known false positives

• Generic numeric sequences such as reference numbers, invoice numbers, or identifiers from other domains Mitigation: Require corroborative evidence keywords within the proximity window to distinguish financial account numbers from general numeric data.
• Phone numbers, postal codes, or other structured numbers with similar digit counts Mitigation: Layer with other detection patterns to deprioritise matches that overlap with phone number or postal code formats.
