Methods of identifying fake license plates;

1. Observing from the font of license plate: Because the font of motor vehicle license plate is a unified national standard, but it is not made uniformly in the whole country, the font and font size structure of license plate are different, but each province has its own characteristics of making motor vehicle license plate, so it is not difficult to distinguish it after careful observation.

2. Observing from the shape of the number plate: the real number plate is processed by high technology and adopts one-step molding technology, with unified overall shape and good visual sense; Fake number plates are made through multiple processes, with different shapes and sizes. The length, width, corner edge and so on are all kinds, as long as the police on duty can find them carefully.
