IBAN & SWIFT Generator

This tool computes international banking identifiers by accepting country code, bank identifier, BBAN components, and optional branch data. It outputs a valid IBAN and, when possible, a SWIFT/BIC code. It is designed for finance teams, corporate treasuries, payment processors, and fintech developers who need reliable identifiers for cross-border transactions or partner enablement. Example inputs: country_code DE, bank_code 10000000, account_number 1234567890 yield an IBAN and a SWIFT BIC when available.

Conceptually it follows ISO 13616 for IBAN construction and ISO 9362 for SWIFT. Inputs are normalized, the BBAN is assembled to the country-specific length, and a checksum is calculated with the standard mod-97 algorithm. The resulting IBAN is formatted per user preference (spaces or compact) and validated against country length rules. Where bank data exists, a best-effort SWIFT/BIC is produced; otherwise no BIC is claimed.

Beneficiaries include finance teams, payment processors, treasuries, and fintech developers integrating banking rails. The value lies in reducing manual validation, speeding onboarding, and enabling consistent formatting across systems.

Core features include input validation, country-specific length checks, checksum validation, optional formatting with spaces, and export-ready strings. Use cases include supplier payments, vendor onboarding, and partner integrations requiring standardized identifiers.
