    How do I find a company's registration number in Poland?

    Search the company's name on KRS / CEIDG at https://ekrs.ms.gov.pl. The result page shows its registration number — the same identifier that appears on invoices, contracts, and government filings.

    Step-by-step

    1. 1

      Open KRS / CEIDG

      Navigate to https://ekrs.ms.gov.pl.

      https://ekrs.ms.gov.pl
    2. 2

      Search by company name

      Type the exact trading or legal name. Partial matches usually work; add the city if the name is common.

    3. 3

      Copy the registration number

      The registration number is displayed at the top of the entity profile. It is the authoritative ID for cross-referencing.

    4. 4

      Confirm it's the right entity

      Check the registered address and incorporation date to be sure you have the correct legal entity, especially for groups with similarly named subsidiaries.

    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.

    Is the Poland company register free to search?

    Yes. Basic company lookups on the KRS / CEIDG are free — you can search by company name or registration number, view legal status, registered address and (usually) directors at no cost. Some jurisdictions charge a small fee only for downloading full filed documents.

    What is the official Poland business registry?

    The KRS / CEIDG is the official public register of companies incorporated in Poland. It is operated by the government and is the primary source cited on this page — https://ekrs.ms.gov.pl.

    Where do I find a Poland company's registration number?

    Every registered Poland entity has a unique registration number issued at incorporation. It appears on invoices, contracts, the company's website footer (often in a "legal" section), and prominently on its KRS / CEIDG record.

    Is a Poland registration number the same as a VAT number?

    No. The registration number is the identifier issued by the KRS / CEIDG when the company was formed. The VAT number is a separate tax identifier issued (only if the company is VAT-registered) by the national tax authority. Many small companies have a registration number but no VAT number.
