Service description

Suomi.fi Messages is the public administration’s shared messaging service. It enables organisations to send messages, decisions and documents to individuals, companies, associations and communities securely in electronic form. When necessary, messages can also be delivered as paper mail.

Already 3.9 million end users receive messages from public authorities electronically. More than 400 organisations use the service to send messages.

Why use Suomi.fi Messages?

Suomi.fi Messages helps organisations move from paper mail to electronic communication. With the service, an organisation can:

  • reduce mailing and processing costs
  • speed up message delivery
  • reduce manual work
  • automate the sending of messages
  • send documents and messages securely.

The Digital and Population Data Services Agency does not charge for implementing the service or for sending electronic messages.

Who can receive messages?

Messages can be sent to individuals, companies, associations and communities. The end user receives the messages in Suomi.fi Messages and can read them after strong authentication in the Suomi.fi web service or the Suomi.fi mobile application.

A secure way to send messages from authorities

Messages are transmitted in encrypted form through a secure channel and can only be accessed after strong authentication. For this reason, messages and documents containing sensitive information can also be sent via Suomi.fi Messages.

Organisations’ obligation to use the service

Some public administration organisations are required to use Suomi.fi Messages. Other organisations have the right to adopt the service voluntarily. Whether an organisation is subject to the obligation or has the right to use the service depends on legislation and the organisation’s duties. More detailed information is available on the page covering the obligation and the right to use the service.

Implementing the service in an organisation

Suomi.fi Messages is used through an organisation’s own system or a commercial off-the-shelf software solution. The service is connected to the Suomi.fi Messages API, after which messages can be sent and received as part of the organisation’s normal processes.

The service does not provide a separate user interface for organisations. Instead, messages are sent and received through the organisation’s own system or a commercial software solution connected to the Suomi.fi Messages API.
