Belgian bank code 507

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.

BE81 5070 0000 0124

Synthetic example: the account part is a placeholder, this IBAN belongs to nobody. It shows where the code sits inside the IBAN.
