The legal status of these plates varies by tribe, with some being recognized by the federal government and others not. Some nations issue plates for both tribal and personal vehicles, while others issue plates only for official tribal vehicles.
Some nations' plates indicate the U.S. state with which they are most closely associated, while others do not. This variation may even exist among the nations associated with one particular state.
Federally recognized tribes may also lease vehicles through the U.S. General Services Administration under certain circumstances. Such vehicles carry U.S. government license plates.
