How IBAN Validation Works
IBAN (International Bank Account Number) is an internationally agreed system for identifying bank accounts. Our validator uses the ISO 13616 standard and mod-97 algorithm to verify IBANs.
IBAN Structure:
- Country Code: 2 letters (e.g., GB for United Kingdom)
- Check Digits: 2 digits for validation
- Bank Identifier: Up to 30 alphanumeric characters
- Account Number: Varies by country
Validation Steps:
- Check country code is valid and supported
- Verify length matches the country's standard
- Apply mod-97 algorithm to check digits
- Extract bank code and account number
FAQ
Which countries use IBAN?
IBAN is used in 70+ countries, including all EU countries, UK, Switzerland, Norway, and many others in Europe, Middle East, and North Africa. The US, Canada, Australia, and New Zealand do not use IBAN.
Does validation mean the account exists?
No. This validator checks if the IBAN format and checksum are correct. It does NOT verify if the account is active or exists. Only the bank can confirm that.
Is my IBAN safe when using this tool?
Yes. All validation happens in your browser. Your IBAN is never sent to our servers or stored anywhere. However, always be cautious about entering sensitive banking information online.
