Postal Code Services
Postal Code Services are free files that provide up-to-date information about postal codes and addresses in Finnish municipalities and postal code areas. You can connect them to your company's address databases and facilitate the maintenance of mailing lists and address registers. The files do not contain street names, map data or other positioning data.
