Bankleitzahl 10017997

IBAN structure with this code

A German IBAN is DE, two check digits, the eight-digit Bankleitzahl, then the ten-digit account number. The BLZ is what the register can vouch for; the account number is known only to the bank.

DE09 1001 7997 1000 0000 00

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