Population Information System query interface for the public sector

The Digital and Population Data Services Agency provides the Population Information System query interface for public organisations. Using the service requires a data permit and the organisation’s commitment to comply with the permit conditions. The scope of the data content is defined on an organisation-specific basis according to the needs of official duties.

Using the Population Information System query interface requires the use of the Suomi.fi Data Exchange Layer. Using a server certificate is possible with an exception permit.
