Finland's 'classic' postal system

Finland Post Corporation - Businesses - Address Register Management - Address Register Maintenance and Update - Postal Code Products - Postal Code Regions

Finland is divided into postal code regions shown on the map. The first two digits of the postal code indicate the area of the locality. The last three digits of a postal code indicate to which receiving post office inside the postal code area an item is delivered.
