How to use the checker
- Copy the IBAN from the invoice, message or bank letter and paste it in the box.
- Tap Check IBAN.
- If it fails, the result says why: wrong length, a letter where a digit should be, or check digits that do not match. Compare it with the original and correct it.
Good to know
- An IBAN always starts with two letters for the country and two check digits.
- The length is fixed for each country, from 15 characters in Norway to 33 in Russia.
- A valid format is not proof of the account. Before a large payment, confirm the IBAN with the receiver by phone or in person.
Common questions
What does the IBAN checker test?
Four things: that the country code is in the IBAN registry, that the length is right for that country, that letters and digits are in the right places, and that the two check digits match the rest.
Does a valid result mean the account exists?
No. It means the IBAN is written without a mistake. Only the bank knows whether the account exists and who owns it.
Is the IBAN I type sent anywhere?
No. The check runs in your own browser. Nothing you type is sent to this site or stored by it.
Why is there no IBAN for my Indian bank account?
India does not use IBAN. For transfers from abroad, Indian banks use the account number with the bank's SWIFT code. Countries without IBAN.
