Custom plates are personalized license plates that allow vehicle owners to display unique combinations of letters and numbers. These plates can reflect a person's name, interests, or a special message, making them a popular choice for those who want to stand out on the road. Each state in the United States has its own rules and fees for obtaining custom plates. To get a custom plate, individuals typically need to apply through their state's Department of Motor Vehicles (DMV) or equivalent agency. The application process often includes checking the availability of the desired combination and paying an additional fee on top of standard registration costs.
