Where is the engine number of a motor vehicle located?

[LeAdaline]

Motor vehicle engine numbers can be found on the vehicle license, motor vehicle registration certificate, car purchase invoice, factory certificate, operating license for commercial vehicles, vehicle purchase tax payment certificate, public security authority registration records, vehicle insurance card, and the actual engine (usually on the engine nameplate). The engine number is an identification code assigned by the engine manufacturer in accordance with relevant regulations, corporate or industry practices, and the attributes of the engine, for a batch of identical products. It represents information such as the manufacturer, specifications, performance, features, technology, purpose, and production batch of the engine. This includes details like fuel type, number of cylinders, displacement, and static braking power.
