The KNF keeps a public register of investment firms, which contains names, addresses of registered offices, and information on the brokerage activities performed by each firm. The register presents separately brokerage houses, brokerage offices, foreign investment firms (separately those which have a branch in Poland and those which do not have any branch), and tied agents. The register is available on the KNF website. It is also useful to use the search engine, which allows users to find a relevant entity by its full or partial name.
