Engine Number
The engine number is a unique serial number stamped on the engine block that identifies that individual engine.
What is Engine Number?
It is different from the engine code, which identifies the engine type. Some registration documents list the engine number. Its location varies by manufacturer. Insurers and registration offices may check the engine number after an engine replacement.
How it works
It is stamped or laser-marked on a machined area of the block during manufacture.
Why it matters for your car
After an engine swap, documents may need updating. A ground-off number is a warning sign.
