Belgian bank code 651

IBAN structure with this code

A Belgian IBAN is BE, two check digits, the three-digit bank identifier, the seven-digit account number, then two national check digits (the first ten digits modulo 97). The identifier is what the NBB list can vouch for; the account number is known only to the bank.
