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.

FAQ

How does IBAN validation work?
IBAN validation uses the ISO 13616 Modulo 97 algorithm. The country code and check digits are moved to the end, letters are converted to numbers (A=10, B=11...), and the resulting number is divided by 97. A valid IBAN always produces a remainder of 1.
What countries are supported?
This tool validates IBANs from over 70 countries that have adopted the IBAN standard, including all EU/EEA nations, the UK, Saudi Arabia, Brazil, and others. Each country has specific length and format requirements that are checked automatically.
What is the difference between IBAN and BIC/SWIFT?
An IBAN (International Bank Account Number) identifies a specific bank account, while a BIC/SWIFT code identifies the bank itself. Together they provide complete routing information for international wire transfers. This tool validates both formats.
