Core Tools

IBANtool hosts two primary free banking utilities that run locally in your web browser, with no required user account or signup step.

IBAN Validator

The IBAN validation tool checks full compliance with the ISO 13616 standard. It verifies IBAN format, correct country-specific length, and runs the MOD 97-10 check digit algorithm to confirm the identifier's structural validity. Validation results include a full breakdown of the IBAN components, formatted display options, and support for all 53 registered ISO 13616 countries.

Validation is not confirmation that the corresponding bank account exists, is active, or belongs to the intended recipient. Always cross-check final details directly with the receiving bank before initiating any international transfer.

SWIFT / BIC Code Lookup

The SWIFT lookup tool covers data from more than 178 banks across 50+ countries. Users can search by bank name or country to find valid SWIFT codes, or paste an existing SWIFT code to decode its component parts: 4-character bank code, 2-character country code, 2-character location code, and optional 3-character branch suffix. This helps prevent routing errors that can misdirect international wire payments.

Key Features

100% client-side execution: No IBAN or SWIFT code values entered by the user are uploaded to the application server during validation or lookup.
No mandatory signup: All tools are accessible immediately without account creation or personal information submission.
Developer-friendly outputs: Copy fully formatted IBAN values, inspect structured breakdown data, and test integration use cases directly in the browser.
