What is the National Criminal Register?
The National Criminal Register, commonly referred to in Poland as the KRK, is the official state register containing information on selected criminal law matters, including final convictions, certain decisions issued in criminal proceedings and data concerning collective entities subject to liability under Polish law. The register operates on the basis of the Act of 24 May 2000 on the National Criminal Register and is maintained by the Polish Minister of Justice.
The KRK is not a publicly accessible database. Information from the register may be obtained by authorised public authorities, courts, prosecutors and other bodies acting within their statutory powers. A person or entity may also request information concerning themselves. In practice, the document issued by the register is often described as a criminal record certificate or a certificate of no criminal record, although the formal document is information from the National Criminal Register.
The main role of the KRK is to provide reliable confirmation of whether a person or entity is recorded in the register. This can be relevant in criminal proceedings, employment, licensing, public procurement, regulated professions, corporate compliance, immigration matters and administrative proceedings. The KRK also supports the exchange of criminal record information within the European Union, including through mechanisms such as ECRIS, where applicable.
What does the National Criminal Register include?
The scope of data held in the KRK depends on statutory rules. In general, the register may contain information on persons finally convicted of offences or fiscal offences, persons in respect of whom criminal proceedings were conditionally discontinued, persons subject to certain security measures, as well as other categories specified by law. It may also include information concerning collective entities held liable for prohibited acts under Polish regulations.
For practical purposes, the most common use of the KRK is to verify whether a person has a criminal record that is relevant for a specific legal purpose. This does not mean that every historical contact with law enforcement appears in the register. For example, the mere fact that someone was questioned by the police or was a suspect in discontinued proceedings does not automatically mean that the person will have an entry in the KRK. The legal basis, the type of decision and its finality are decisive.
Entries in the KRK are also affected by rules on expungement and deletion of convictions. Under Polish criminal law, after statutory conditions are met, a conviction may be treated as expunged, and the person is generally considered not to have been convicted in respect of that conviction. The assessment of whether a specific entry should still appear in the register requires analysis of the judgment, the offence, the penalty imposed and the applicable provisions.
When is information from the KRK needed?
Information from the National Criminal Register may be required in many legal and business situations. Individuals often need it when applying for employment in positions where clean criminal record requirements are imposed by law, for example in education, security, financial services, transport or other regulated sectors. It may also be required in licensing procedures, adoption-related matters, residence or visa procedures, or when applying for specific public authorisations.
Entrepreneurs may need KRK information when participating in public procurement procedures, appointing management board members, verifying statutory eligibility requirements or implementing internal compliance procedures. In corporate practice, criminal record verification can be relevant where the law excludes persons convicted of certain offences from performing specific functions or where contractual partners require confirmation of compliance with legal standards.
The KRK is also important in cross-border matters. A Polish criminal record may be requested by foreign employers, authorities or courts. Conversely, in some cases Polish authorities may need information about convictions from other jurisdictions. The scope and evidentiary value of such information may depend on the country involved, the applicable international or EU rules and the purpose for which the certificate is requested.
Why should KRK matters be verified carefully?
Incorrect assumptions about the KRK may lead to practical and legal problems. A person may believe that a conviction has already been deleted, while the register still contains an entry. An employer may request a criminal record certificate without a proper legal basis. A company may submit incomplete information in a public procurement procedure. In immigration or licensing matters, an inaccurate statement about criminal record status may affect the outcome of the case.
A timely legal consultation can help determine whether a KRK certificate is required, who may lawfully request it, what type of information should be obtained and how to respond if the register contains an entry. Early verification may help avoid procedural errors, disputes with authorities, reputational consequences, liability for false declarations or financial losses connected with rejected applications or exclusion from proceedings.
