Number of permanent offices staffed by administration officials this is information about Postal establishments. Postal establishments can be classified in two categories: offices open to the public and offices not open to the public.
Postal establishments open to the public are post offices to which customers may go for postal services. Offices open to the public may be staffed by officials of the designated operator or by persons not connected with the designated operator, and they may be fixed (permanent) or mobile.
Offices staffed by designated operator officials may be full-service offices or secondary offices. Fullservice post offices are post offices to which, in principle, customers may go for all postal services. This category also includes sections of exchange offices or sorting offices offering similar services. Secondary offices generally have reduced services and, in principle, depend on a head post office.
