    What does Roskaposti or Tuntematon mean as the sender of a text message?

    How Finland labels text messages from unverified senders.

    Answered at: Checked at:

    Short answer

    They are warnings. Traficom requires operators to check that an organisation has the right to use the sender name shown in a text message. From 4 May 2026 an unverified sender name was replaced with Tuntematon, meaning unknown. From 2 November 2026 the name is replaced with Roskaposti, meaning spam, or the message is blocked. Treat any such message with care and do not click its links.

    Why

    1. Traficom lists 4 May 2026 as the date when unverified sender IDs became Tuntematon.
    2. Traficom lists 2 November 2026 as the date for the change to Roskaposti.
    3. Verkkouutiset notes that not every Roskaposti message is a scam.

    Details

    The rules concern sender names, such as a company or authority name. Text messages sent by private people from their own phone numbers work as before.

    Tip

    If a message claims to come from your bank or Posti but shows Roskaposti, check the matter in the official app or website instead.

    What may differ

    Foreign organisations can still send texts with their own local sender IDs, and some of these may be labelled too.

    Common misconception

    A message labelled Roskaposti is always a scam.

    What actually happens

    It means the sender could not be verified. Most are worth ignoring, but some genuine messages can be labelled too.
