If an owner wishes to have two license plates, the registrar or deputy registrar shall deliver two license plates, duplicates of each other, and, when required, a validation sticker, or a validation sticker alone, to be attached to the number plates as provided in section 4503.191 of the Revised Code. The owner shall display the license plate and, when required, the validation sticker on the rear of the vehicle. However, a commercial tractor shall display the license plate on the front of the commercial tractor and a chauffeured limousine shall display a livery sticker along with a validation sticker as provided in section 4503.24 of the Revised Code.
Additionally, the registrar and each deputy registrar who either issues a license plate and a validation sticker for use on any vehicle other than a commercial tractor, semitrailer, or apportioned vehicle, or who issues a validation sticker alone for use on such a vehicle and the owner has changed the owner's county of residence since the owner last was issued a county identification sticker, also shall issue and deliver to the owner a county identification sticker, which shall be attached to the license plate in a manner prescribed by the director of public safety. The county identification sticker shall identify prominently by name or number the county in which the owner of the vehicle resides at the time of registration.
