A license plate is a metal or plastic tag attached to a vehicle, displaying a unique combination of letters and numbers. This combination serves as an identifier for the vehicle, allowing law enforcement and other authorities to track ownership and registration. License plates are typically issued by government agencies and vary by region, often featuring specific designs or symbols. In many places, license plates must be renewed periodically, and they may also include information such as the vehicle's registration expiration date. Some regions offer personalized plates, allowing vehicle owners to choose their own combinations, making their vehicles more distinctive.
