BankCodeKit Financial Code Tools

Explore free browser-local utilities for IBAN, BIC/SWIFT, and SEPA payment-code checks. The tools validate formats and payment-code rules locally in the browser without uploading values, requiring a login, or storing sensitive payment details.

Choose a tool

How to choose the right tool

  • Use the IBAN Checker for one value when you need a detailed pass/fail explanation.
  • Use the Bulk IBAN Validator when you have multiple lines to review locally.
  • Use the BIC/SWIFT Checker when the bank identifier format is the main question.
  • Use the SEPA Country Checker when you need country-level SEPA scope context.
  • Use the Invoice Formatter when you want clean payment detail text after format checks.
  • Use the Test IBAN Generator only for software testing, QA, and demos.

Privacy model

BankCodeKit is designed for quick no-login checks where sensitive values should remain on the device. User-entered IBANs, BICs, invoice details, CSV rows, and payment references should not be sent to servers, analytics, ad scripts, logs, or URLs.

Limitations

These utilities help identify structural issues and readable formatting problems. They do not replace confirmation from a bank, payment provider, invoice issuer, payee, or licensed directory.

  • Format validation only
  • No account existence confirmation
  • No account ownership confirmation
  • No payment success guarantee

Before using any payment result

Treat every result as a format check, not approval to send money. A typo can pass some structural rules, and a structurally valid value can still be wrong for the person, company, invoice, or payment you intend to make.
