Diplomatic plates are special vehicle registration plates used by diplomats and their families. These plates signify that the vehicle is owned by a diplomatic mission or an international organization, granting certain privileges and immunities under international law. The use of diplomatic plates helps facilitate the movement of diplomats, allowing them to perform their duties without the usual restrictions faced by regular vehicles. Typically, these plates are marked with a unique code or emblem that identifies the issuing country or organization, such as the United Nations or a specific embassy.
