IBAN validator
Check an IBAN's validity (ISO 13616 mod-97 checksum) and break down a French RIB. 100% local, no data sent.
The check is purely arithmetic: your IBAN never leaves your browser.
Enter an IBAN
Paste an IBAN to check its validity and, if French, break down the RIB.
How does the check work?
A valid IBAN follows a country-specific length and a mod-97 checksum (ISO 13616). The check confirms there is no typo; it does not guarantee that the account exists or is active.
