Yes. Every company must have a registered office address (business registration address) located within the territory of Poland in order to be entered into the National Court Register (KRS). This address is used for official correspondence and appears in public records. It can be either a physical office or a virtual office that complies with all formal requirements. Without an address, it is not possible to register the company or start operations, which is why choosing one should be part of the planning stage of the company formation process.
