Israel Bank Account Number

Detects Israel Bank Account Number patterns. This pattern is based on a Microsoft Purview built-in sensitive information type. Financial account numbers require corroborative evidence for reliable detection due to their generic numeric format.

Confidence

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.

Should match

• 12-345-12345678 — Israeli bank account with hyphen separators
• 1234512345678 — Israeli bank account continuous digits
• 98-765-98765432 — Israeli bank account format

Should not match

• 12-345-1234567 — Only 7 digits in account section, too short
• 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
• template example placeholder record identifier — Template/sample context should be excluded even when anchor words are present

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.
