About This Tool
What is an IBAN?
IBAN stands for International Bank Account Number. It is an internationally agreed system of identifying bank accounts across national borders to facilitate easier communication and faster processing of transactions.
A standard IBAN contains a two-letter country code, two check digits, and a long string of alphanumeric characters known as the BBAN. Our validator ensures that these components are not only present but mathematically consistent with the ISO 13616 standard.
Why Use This Tool
Zero-Knowledge Security
Bank details are highly sensitive. Unlike many online financial tools that transmit your data to a backend server, our validator runs **100% locally in your browser**. We never store, log, or transmit your IBAN or BIC codes. Your privacy is protected by the same sandboxed environment that powers modern web browsers.
