Quickly validate and verify an IBAN for errors
(The entered IBAN codes are validated using the MOD 97-10 algorithm and are never stored in our database.)
What is an IBAN?
The International Bank Account Number (IBAN) is a standardized banking code used to identify a customer's account internationally. It ensures secure and accurate payment processing between banks and financial institutions across different countries.
An IBAN consists of letters and numbers that represent an individual bank account. The format and validity of an IBAN are verified using the MOD 97-10 algorithm, which helps detect errors caused by incorrect characters in the IBAN code.
NOTE: Our IBAN validator checks the format of the IBAN but does not confirm the existence of the account.
What is SEPA?
SEPA (Single Euro Payments Area) is a system that simplifies euro-denominated payments across EU countries and select non-EU nations. It allows individuals and businesses to transfer money across borders just as easily and affordably as domestic interbank payments. Our tool helps you determine whether your bank account belongs to a SEPA country.
Which countries use IBAN?
IBAN is used primarily in Europe and some non-European countries to ensure secure and standardized international bank transfers. Countries like the United Kingdom, Germany, France, Spain, and Italy require IBAN for cross-border transactions. However, the United States, Canada, and Australia do not use IBAN, relying instead on SWIFT/BIC codes and routing numbers.
Common IBAN errors and how to fix them
- Incorrect country code (e.g., entering 'GB' instead of 'DE').
- Wrong check digits (caused by manual input errors).
- Missing or extra characters (IBANs have a fixed length per country).
To avoid these errors, always double-check your IBAN using an official IBAN validator before making a transaction.
