How Ria's IBAN validator works
Paste the IBAN you've been given (spaces are okay).
Click Validate. We'll confirm the country code, check the length against the country standard, and run the mod-97 check-digit formula.
Review the breakdown showing each part of the IBAN: country, check digits, bank, and account.
If the format is valid, double-check it with your recipient and send your money with confidence.
A valid format isn't a guarantee that the account exists or belongs to the right person. Always confirm with your recipient before sending.
What happens if the IBAN is wrong?
If you enter an invalid IBAN when sending money:
Your bank will usually reject the transfer up front. You may still be charged a small return fee.
If the IBAN is valid but belongs to the wrong account, the money can land with the wrong person, and recovering it is on you.
Some banks let you cancel a transfer within a short window, but only if the funds haven't already cleared. Contact your bank immediately if you suspect an error.
Validating before you send is free, takes a few seconds, and is the easiest way to catch a mistake before it becomes a problem.
Common IBAN mistakes to watch for
Typos: IBANs are long and easy to mistype. Always copy and paste when you can.
Wrong country code: the first two letters must match the country where the account is held, not where the recipient lives.
Zeroes vs. Os, ones vs. Ls: IBANs use only A-Z and 0-9. There are no lowercase letters.
Print format vs. digital format: when paying online, drop the spaces. Some payment systems reject IBANs with spaces.
Old IBAN, new account: if your recipient changed banks, always ask for their latest details rather than reusing an old number.
IBAN validator vs. account verification
Ria's validator runs the same format checks banks use: country code, length, and the mod-97 check digit. That tells you the IBAN is mathematically valid.
Account verification (sometimes called Confirmation of Payee) is a separate step that confirms the IBAN actually belongs to the person you're paying. That check happens inside your bank or payment provider, not on a public tool. Use both together: validate the format here, then ask your recipient or their bank to confirm the account name before you send.
