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

    Use the exact KRS with its issuing jurisdiction or register on KRS / CEIDG. 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 KRS on the paperwork

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

    2. 2

      Search the KRS

      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 KRS / CEIDG

      For anything contractual, confirm the number against the primary source at https://ekrs.ms.gov.pl.

    Poland: choosing and checking the right record

    Choose the correct source
    Choose KRS for entities within the National Court Register and CEIDG for sole-trader registration. Use the official government search routes rather than assuming every Polish business must have a KRS record.
    Confirm the entity
    Keep KRS, NIP and REGON numbers distinct. Compare the full legal name and available address with the contracting entity. Read representation rules separately from the list of management-board members.

    Frequently asked questions

    What is a KRS in Poland?

    It is the identifier KRS / CEIDG 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 KRS lookup free?

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

    What if the KRS 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 KRS or the company name?

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

    What is a sp. z o.o.?

    Sp. z o.o. (Spółka z ograniczoną odpowiedzialnością) is Poland's limited liability company, equivalent to a GmbH or Ltd. Minimum share capital is PLN 5,000 (about €1,100). It's the most popular company form for small and medium businesses.
