Prisoners make license plates in some states such as Michigan and New Jersey, according to the Michigan License Plate factory and NJ.com. Some states, such as Indiana, no longer use inmates to manufacture license plates, according to USA Today.
The Michigan License Plate Factory produces around 8,000 plates each day, manufactured by inmates from the Gus Harrison Correctional Facility. In New Jersey, inmates manufacture over 1 million license plates each year and are paid less than $1 per hour for their labor. Indiana transferred license plate production to an outside vendor, Intellectual Technology Inc., in order to reduce manufacturing costs, according to TheStatehouseFile.com.
