FAQ
Is this checker provided by a bank?
No. IBAN Tools is an independent technical checker for format, length and checksum. It is not a bank and does not provide official banking confirmation.
Can an IBAN be valid but still not belong to an active account?
Yes. A valid IBAN checksum only means the number has a technically valid structure. It does not prove that the account exists or can receive payments.
Can I find out who owns an IBAN?
No. This checker does not verify account holders and does not confirm who owns an IBAN.
What does the IBAN checksum check mean?
The checksum is a mathematical check designed to catch many typing mistakes. It is not an account lookup or bank confirmation.
Does IBAN Tools store my IBAN?
The tool is designed for technical checking on the page. IBAN input should not be stored, logged, or sent to analytics.
