Frequently Asked Questions
How does the MOD-97 algorithm validate an IBAN?
The first four characters (country code and check digits) are moved to the end, letters are converted to digits (A=10 to Z=35), and the resulting integer is divided by 97. If the remainder equals 1, the IBAN is mathematically valid.
