How do I validate an IBAN?

What is an IBAN validator?
An IBAN validator is a tool that checks International Bank Account Numbers for correctness using the mod-97 algorithm, country code verification, and length validation. It ensures the IBAN is properly formatted and mathematically valid before making international payments.
Is this IBAN validator free?
Yes, completely free with unlimited validations. No signup required, no watermarks, and all processing happens in your browser for complete privacy. Validate as many IBANs as needed for banking, accounting, or payment processing.
How does IBAN validation work?
IBAN validation uses the mod-97 algorithm defined in ISO 13616. The algorithm checks the mathematical relationship between the account number and check digits to ensure accuracy.
Which countries support IBAN?
Over 70 countries support IBAN, including all EU/SEPA countries plus many others like Brazil, Saudi Arabia, and Turkey. The tool supports all major IBAN countries.
What is the difference between IBAN and BIC?
IBAN identifies the specific bank account, while BIC (Bank Identifier Code) identifies the bank itself. For SEPA payments, IBAN alone is usually sufficient.
Can I use this for SEPA payments?
Yes, the tool indicates SEPA support for each country. SEPA countries can receive EUR payments using just the IBAN without requiring a BIC code.
Is the bank information lookup accurate?
Bank information is based on publicly available data and may not be complete for all banks. For critical applications, verify with official banking databases.
