SWIFT or BIC codes

Detects references to SWIFT or BIC codes in financial and compliance documents. Commonly found in Australian regulatory filings, transaction records, and audit documentation. Phrase-level payment-rail concept detection anchored on explicit SWIFT/BIC vocabulary; it does not parse 8- or 11-character BIC values.

Known false positives

Financial terminology appearing in published reports, accounting textbooks, regulatory guidance, or template documents without actual transaction data. Mitigation: Require corroborative evidence keywords within the proximity window. Cross-reference with structured financial identifiers to confirm actual sensitive data.
In Australian English, standard business terminology overlapping with financial detection keywords in routine correspondence and documentation. Mitigation: Increase confidence threshold when scanning business correspondence. Layer with transaction-specific patterns for higher precision.
