IBAN Validator
Check if an International Bank Account Number (IBAN) is valid based on its structure and checksum.
The IBAN (International Bank Account Number) Validator is a tool designed to check the integrity of an IBAN. It confirms that the IBAN follows the correct format for its specific country, including length and character types, and validates it using a MOD-97 checksum. This is essential for reducing transaction errors in international payments. This tool performs all checks in your browser, ensuring the IBAN data you enter remains private.
Our tool performs several checks:
- Structure Check: Verifies that the IBAN's length and character composition (letters, numbers) match the standard for the country code specified in the first two characters.
- Checksum Validation: The IBAN is rearranged and converted to an integer, then a mathematical operation (modulus 97) is performed. For a valid IBAN, the result of this operation must be 1. This check catches nearly all transcription errors.
Does a valid IBAN guarantee the bank account exists?
No. This tool validates that the IBAN is structured correctly, but it does not and cannot check if the account actually exists or is active. It is a tool for preventing errors before a transaction, not for verifying account existence.
Can I enter IBANs with spaces?
Yes. The tool automatically removes spaces from the input before validation, so you can paste IBANs in either electronic or print format.
Is my data secure?
Yes. All validation is performed on your device in your browser. The IBAN you enter is never sent to our servers, ensuring complete confidentiality.
