    How do I look up a company by its registration number in Finland?

    Use the exact Y-tunnus with its issuing jurisdiction or register on PRH. Compare the returned legal name and identifier. A valid-looking number does not guarantee a result: coverage, formatting, access and source availability affect the lookup.

    Step-by-step

    1. 1

      Find the Y-tunnus on the paperwork

      The Y-tunnus normally appears on invoices, contracts, the website footer or official correspondence. It is the number counterparties are required to quote.

    2. 2

      Search the Y-tunnus

      Preserve leading zeros, letters, court and jurisdiction information. Follow the source's documented format rather than removing meaningful parts to force a match.

    3. 3

      Confirm the returned entity

      Check the legal name on the returned record matches the name on your paperwork. A mismatch between quoted number and quoted name is a serious warning sign.

    4. 4

      Verify at PRH

      For anything contractual, confirm the number against the primary source at https://www.ytj.fi.

    Frequently asked questions

    What is a Y-tunnus in Finland?

    It is the identifier PRH assigns to a registered entity. It stays with the entity even if the trading name changes, which makes it the reliable way to track a company over time.

    Is a Y-tunnus lookup free?

    LemReveal's basic lookup is free where supported. Check PRH's official access rules for the record or document required.

    What if the Y-tunnus returns no result?

    Check the format, issuing jurisdiction, coverage and source availability. Preserve meaningful prefixes and leading zeros. An unavailable source is not a confirmed absence; ask the counterparty to clarify the identifier.

    Should I use the Y-tunnus or the company name?

    The Y-tunnus. Names are duplicated across entities within a group; the number is unique to one entity.

    What is a Y-tunnus?

    Y-tunnus (Business ID) is a 7+1 digit identifier (XXXXXXX-X) assigned to every Finnish business by the PRH. It's used for all official interactions including tax, VAT, and trade register matters.
