What do the letters on a license plate mean?

The letters on a license plate typically represent a combination of the vehicle's registration details, such as the state or province where the vehicle is registered and a unique identifier for that specific vehicle. These letters can include a mix of alphabetical characters and numbers, often following specific formats defined by local regulations. In some cases, they may also indicate vehicle type, age, or special designations, such as for electric vehicles or commercial use. Overall, the combination serves to identify and differentiate vehicles on the road.
