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.
If your organisation wishes to use Suomi.fi Messages for both electronic messages and paper mail deliveries, you can enable the printing, enveloping and distribution service (TKJ service) for Suomi.fi Messages. The TKJ service must be enabled separately, as it is not included in the deployment of Suomi.fi Messages. The instructions for enabling the service can be found on the Deployment of the printing, enveloping and distribution service page.
Please note that even though Suomi.fi Messages permits sending messages by paper mail, the service is primarily intended for electronic communications. In other words, you cannot rely solely on the TKJ service. Your organisation must ensure that some of your messages will also be delivered electronically through Suomi.fi Messages.
Provider and operating costs of the mailing service
The provider of the TKJ service has been competitively tendered by the Digital and Population Data Services Agency, which means that you will not have to put your mailing service out to tender should you begin using Suomi.fi Messages. Please note that the tendered service can only be used to mail messages sent via Suomi.fi Messages. If you have any other mailing-related needs, your organisation must competitively tender its other mailing services.
The printing and enveloping service is provided by Posti Messaging Oy. Distribution services are provided by Posti Jakelu Oy. The current agreement is valid until 1 October 2026. The Digital and Population Data Services Agency will put the contract out to tender again at the end of the contract period.
Paper mail deliveries are charged in accordance with the price list specified in the agreement between the Digital and Population Data Services Agency and Posti Messaging Oy. If you are considering enabling the TKJ service, you can request the price list from viestit-kayttoonotot@dvv.fi. Any services that fall outside the scope of the agreement tendered by the Digital and Population Data Services Agency are charged in accordance with the general price list of Posti Messaging Oy.
When using the TKJ service, all domestic letters are sent with Economy class. The delivery of international letters is not included in the TKJ service pricing but is charged according to Posti Messaging Oy’s general price list.
