Where is the engine number located?
2 Answers
The engine number is located on the cylinder block of the engine, typically on the rear or both sides. However, some positions may not be visible to the naked eye and require the use of a lift for inspection. The engine number is also indicated on the vehicle's registration certificate. The engine number is an identification code assigned by the engine manufacturer in accordance with relevant regulations, industry standards, or company practices, based on the attributes of a particular batch of identical products. As the core component of a vehicle, the engine functions similarly to the human brain or a computer's CPU. Every car has its unique engine number, much like a human's ID number. The engine number plays a crucial role, as it remains essential regardless of any modifications made to the vehicle.
Having driven for over a decade, I'm quite familiar with locating engine numbers. They're typically engraved on the top or front side of the engine block, near the oil filler cap, requiring a careful look under the hood. Sometimes dust or grease may obscure it, so wiping with a cloth helps. I've noticed positions vary by model: German cars often place it on the left, Japanese models on the right. Remember, it's printed on the vehicle registration or license certificate—always good to photograph as backup for maintenance or ownership transfers. Losing it isn't an option since it proves vehicle identity. I advise beginners to check regularly for peace of mind.
