I recommend the Polish license plates application (with map)! The application does not represent a government entity. The application includes: - a map of Poland with all Polish counties and the assigned license plate - a list of all counties with information about the voivodeship, the county capital, and license plates Clicking on an item takes you to the map. Some best features: - interactive map - full list of counties - sorting by number, district, voivodeship and district capital - sear
