IBANtool

IBANtool is a free online toolkit for cross-border payments. Validate IBANs with ISO 13616 format, length, and MOD 97 checks, and look up SWIFT/BIC codes for major banks. Everything runs client-side: your account numbers are not uploaded to our servers. No account required. Includes country IBAN format references and examples for 50+ countries — built for developers, freelancers, and anyone checking payment details before a wire. The site bundles four tools: an IBAN Validator (53 countries, shows country code, check digits and BBAN), a SWIFT/BIC Code Lookup (178+ banks in 50+ countries), IBAN to SWIFT, and an IBAN Generator that creates MOD 97-valid test IBANs for developers and QA. Country reference pages list the ISO 13616 format, length and a worked example. IBANtool checks structure, not whether an account exists, and is not affiliated with SWIFT, ISO or any bank.
