IMPORTANT

Generated values are synthetic and structurally valid, but RandomIBAN does not query banks or account directories. A generated value could coincidentally match an issued account. Use it only in isolated test, demo, or educational environments. Never use generated IBANs for real payments, production customer records, fraud, or impersonation.

RandomIBAN is an independent developer utility and is not affiliated with SWIFT, ISO, or any bank.
