About this Validator
This tool validates Polish National Official Business Register Numbers according to official requirements.
The validator checks if a given REGON follows the correct structure for both national entities (9 digits) and local units (14 digits).
This validation only confirms if a REGON follows the correct format. It does not verify if the number is actually registered with Statistics Poland (GUS).
