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

    Enter the FN to look up a Austria company directly on Firmenbuch. Unlike a name search, an FN 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 FN on the paperwork

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

    2. 2

      Search the FN

      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 Firmenbuch

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

    Is a FN lookup free?

    Yes. Looking up a company by FN on Firmenbuch is free and requires no account.

    What if the FN returns no result?

    Re-enter it without spaces or punctuation first. If it still returns nothing, the number may be mistyped, belong to a different country's register, or not exist — ask the counterparty to confirm it in writing.

    Should I use the FN or the company name?
