Austrian bank code 10000

IBAN structure with this code

An Austrian IBAN is AT, two check digits, the five-digit bank code, then the eleven-digit account number. The bank code is what the OeNB directory can vouch for; the account number is known only to the bank.

AT37 1000 0000 0000 0001

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