Some vehicles in Wisconsin require a front license plate. The vehicles on which you have to have one are passenger cars and light trucks, unless they are government vehicles.
You should have a title in your name with a lien on it, at least, to obtain a license plate.
Wisconsin allows you to look up a license plate number for your own personal purposes. You can look up your license plate number to find out when your plates expire, if you will need an emissions test, whether your plates are suspended or not and you will get your RRN number this way as well.
Both plates are required on all cars and trucks in Wisconsin.
