Deployment of the printing, enveloping and distribution service

Update 24.9.2026: Provider of the Suomi.fi Messages printing, enveloping and distribution service (TKJ service) will change

  • The Digital and Population Data Services Agency has selected Edita Prima as the new provider of the TKJ service for Suomi.fi Messages following a competitive tendering process. For paper-based verifiable service, Posti Messaging will continue as the service provider.
  • The change of provider will include a transition period of several months.
  • Together with the current provider, Posti Messaging, the Digital and Population Data Services Agency has ensured that the TKJ service will remain available without interruption throughout the transition period.
  • In the coming weeks, the Digital and Population Data Services Agency will provide more information about the timetable, the effects of the change and any actions required. We will contact all organisations and system providers that currently use the TKJ service.
  • If your system does not yet support the TKJ service but support for the service is being planned, please contact Suomi.fi Messages deployment support at viestit-kayttoonotot@dvv.fi. We will explain what should be taken into account when implementing the service.

The printing, enveloping and distribution service (TKJ service) makes it possible to send paper mail through Suomi.fi Messages. You can read about the functionality in more detail on the page Sending paper mail.

Please note that the TKJ service is available only if your organisation also uses Suomi.fi Messages to send messages electronically.

You will find the different stages of the deployment process of the TKJ service below. It is advisable to already enable the TKJ service as part of the deployment process of Suomi.fi Messages so that you can plan the entire process at the same time.
