How an IBAN is built
Every IBAN starts with a 2-letter country code and 2 check digits, followed by the national account number (BBAN). The length is fixed per country, from 15 characters (Norway) to 32 (Saint Lucia). The check digits use the mod-97 rule, so most typing mistakes are caught before a payment goes out.
