The bank will open an account on the basis of a valid OP, where the permanent residence is stated. As a rule, no one examines in which building the permanent residence is located. Thus, if the Municipal Office in Horní Dolní is listed in the OP and you set up an account elsewhere or even online, it will be difficult to find out that the given address is the address of the OÚ. In addition, permanent residence at the district office is only an indication in the OP, you can state another correspondence address, ie the one to which the statements will go, etc.
