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.
PLEASE NOTE Downloading postal codes will change on May 23, 2017. After the change, files can no longer be retrieved from the FTP server. Automatic retrieval will also become unavailable. From May 23, postal code services can be downloaded directly from the posti.fi website.
