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

    Enter the Y-tunnus to look up a Finland company directly on PRH. Unlike a name search, an Y-tunnus returns exactly one entity, which is why it is the identifier to use for KYC, invoicing and contract checks.

    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

      Enter the number exactly as printed. Punctuation and spacing vary between documents — strip them if the search returns nothing.

    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.
