A Polish EU VAT number can be checked free of charge using the VIES search tool operated by the European Commission.
To perform the check, the user selects Poland as the relevant EU Member State and enters the company’s Polish VAT number. The system then indicates whether the number is valid for cross-border transactions within the European Union.
VIES is not an independent registration database. It retrieves information from the national VAT databases maintained by individual Member States.
A number may therefore return an invalid result because the company has not registered for EU VAT, its registration is still being processed, it has been removed from the EU VAT register or the national system is temporarily unavailable.
A Polish taxpayer may also request a ZAS-VUE certificate through the Polish e-Tax Office.
