Polish Trade Registry

What the Polish Trade Registry (KRS) is, what information it holds and the steps to register a company in Poland. Our corporate lawyers can assist you.

Polish Trade Registry

The Polish Trade Registry/Polish Business Register is managed by the Polish Ministry of Justice. It provides information about companies, associations and other legal entities.

Any company formed in Poland needs to be registered at the National Court Register in order to receive a unique company ID number (REGON), NIP (Tax Identification Number) and statistical number. Legal persons, organisational units without the status of a legal person, natural persons that perform economic activities and any local units of the aforementioned entities must be entered into The National Official Business Register (REGON). The registration is mandatory and our corporate lawyers in Poland can assist you.

Access to the Polish Register

The REGON register is open for public access. It can be accessed online and it contains both free information about the registered companies ; all REGON data can be searched free of charge. In order to search for a Polish legal entity in the REGON register, the person seeking the information must enter the REGON identification number or the Tax Identification Number.

Information about registered companies that may be obtained free of charge from the REGON register includes the following:

  • REGON identification number;
  • name of the company, address and other identification details: phone and fax numbers, website (if the information is disclosed by the company); 
  • Tax Identification Number;
  • legal form and form of ownership;
  • the company’s main activity and dates regarding the commencement or suspension of such activity.
    Our corporate lawyers in Poland can definitely help you obtain information from the Trade Register.

The National Court Register

When registering one of the available types of companies in Poland, entrepreneurs must first conclude the company agreement (in notarial form or, where allowed, online via the S24 system) and then register the company in the National Court Register. The application for registration is submitted at the Register of Entrepreneurs in the National Court Register (KRS).

The Polish Ministry of Justice also provides an online search option to look for existing companies in the National Register. The website (available in Polish) provides a public search based on the KRS number, other identification numbers and details regarding the location of the company. Insolvency data are now in the separate National Register of Debtors (KRZ), which replaced the KRS Register of Insolvent Debtors in December 2021.
