How to choose the right tool

  • Check one IBAN when you need a detailed pass/fail explanation.
  • Validate a list when you have multiple IBAN lines to review locally.
  • Check a BIC when the bank identifier format is the main question.
  • Check a country when you need country-level SEPA scope context.
  • Copy payment details only after local format checks and acknowledgement.
  • Generate test cases only for software testing, QA, and demos.

Privacy model

BankCodeKit is designed for no-login checks where sensitive values stay 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 and formatting issues. They do not replace confirmation from a bank, payment provider, invoice issuer, payee, or licensed directory.

  • Format validation only
  • No account existence or ownership confirmation
  • No bank connectivity, sanctions, or fraud-risk screening
  • No payment readiness or payment success confirmation

Before using any payment result

Treat every result as a format check, not approval to send money. Verify the payee, account details, amount, currency, and reference through a trusted channel.
