What is IBAN validator?
An IBAN (International Bank Account Number) encodes a country code, check digits, and the underlying bank account number, with a checksum (mod-97) that catches most typos before a payment is even attempted.
How to use it
Enter an IBAN to check its checksum and expected length for that country, and see it broken into country code, check digits, and the underlying account number (BBAN).
