Crefo.pl is a Polish company information and credit-reporting service founded in 2010 by Creditreform, an international credit information agency. Its database covers approximately 2.5 million Polish companies and combines information from public sources, including the National Court Register and the Register of Business Activity, with information gathered through Creditreform interviews.

Users can search for businesses by name, address, legal form, or NCR, VAT, ID, and Crefo numbers. A directory organized by Polish Classification of Activities codes and location offers another way to find companies. The service provides free company addresses and contact details, alongside paid online reports in Mini, Shortened, and Standard versions. Customers can also select specific report data or request offline reports prepared by Creditreform employees, including updated reports that may be completed within eight hours.

Depending on the report, available information can include registration history, organizational structure, financial data and analysis, ownership and personal links, court proceedings, and industry comparisons. Crefo.pl also offers free notifications about changes to selected companies.
