Suomi.fi Messages for companies

You can activate Suomi.fi Messages for your company, association or other organisation with a Finnish Business ID. Suomi.fi Messages is an electronic mailbox where you can receive official messages such as decisions, requests for additional information, invoices and other documents. However, not all authorities using Suomi.fi Messages send messages to companies or associations through the service.

You can also send messages and attachments from your organisation’s electronic mailbox to those organisations that allow incoming messages. You can learn more about how to use Suomi.fi Messages under the section Using Suomi.fi Messages.

Suomi.fi Messages for a company or an association can be used by:

  • persons who are signatories for the company or association, and have the right to represent it alone
  • persons who have been authorised by the company’s or association’s signatory using Suomi.fi e-Authorisations to represent the company or association.

The assignee should always log into e-services using a personal Finnish identification token, i.e. as themselves. If the assignee has the right to act on behalf of a company or organisation, they should choose the company on whose behalf they wish to act after identification.

Other than that, using Messages is the same as when acting as yourself. Please note that when using the  Suomi.fi mobile application, you may only act on behalf of a company if  you are a signatory entered in the company's trade register and you have the right to represent the company alone.

Read more about acting on behalf of an organisation in instructions for Suomi.fi e-Authorizations.

Acting on behalf of a company or association with an e-authorisation

The representative of a company may grant another person a mandate, i.e. the right to act on behalf of the company in Suomi.fi Messages. An e-authorisation can be described as an electronic power of attorney the details of which are entered into the national authorisation register. An authorisation cannot be limited to e.g. messages from a specific sender; the assignee can always see the entire contents of the mailbox.

The assignee can use Suomi.fi Messages according to the scope of the mandate granted in the following matters:

Management of electronic communications

  • The assignee may consent to the electronic transfer of messages, manage message settings, delete messages and read and send electronic messages on behalf of the assignor.

Reading and sending electronic messages

  • The assignee can read and send electronic messages on behalf of the assignor.

Reading electronic messages

  • The assignee may read electronic messages on behalf of the assignor.
