Verify an IBAN number safely
You can use the result to catch common typing errors before using an IBAN, but you should still confirm payment details through trusted banking or business channels when money is involved.
What it cannot verify
This IBAN verification tool does not verify account existence, account holder identity, bank account status, or whether a payment will be accepted by a bank.
How IBAN verification works
Technical IBAN verification normalizes the input, moves the first four characters to the end, converts letters to numbers, and checks the result with the ISO 13616 mod-97 algorithm.

FAQ
Is this a bank-provided IBAN verification service?
No. It is a technical format and checksum tool. It does not provide official confirmation from a bank, payment provider or account registry.
Can this identify who owns the account?
No. IBAN Tools does not verify who owns an account and cannot match an IBAN to a person or company.
Can this prove that an account is real or active?
No. A technically valid IBAN can still refer to a closed, inactive, mistyped or otherwise unusable payment destination.
What does a valid IBAN checksum mean?
It means the IBAN passes a mathematical check that helps detect many errors. It does not guarantee that the IBAN belongs to a real or active account.
Is my IBAN stored?
The tool is intended for on-page technical verification. IBAN input should not be stored, logged, or sent to analytics.
