Custom license plates are personalized vehicle registration plates that allow individuals to display unique combinations of letters, numbers, and sometimes symbols. These plates can reflect a person's name, interests, or a special message, making them a popular choice for car owners who want to stand out. In many regions, including the United States, individuals can apply for custom plates through their local Department of Motor Vehicles (DMV). There may be specific guidelines regarding character limits and prohibited phrases, and fees often apply for the customization process. Custom plates can also support various causes or organizations, adding a personal touch to vehicles.
