No, the engine number and chassis number are not the same. The engine number is located on the engine block, while the chassis number is found on the vehicle's body. The engine number serves as the ID number for the engine, whereas the chassis number acts as the ID number for the entire vehicle. Additionally, the number of digits in the engine number differs from that in the chassis number, with the chassis number being longer. The chassis number is technically referred to as the Vehicle Identification Number (VIN), a unique set of characters assigned by the manufacturer to identify a specific vehicle. The VIN is a 17-character alphanumeric code, also known as the 17-digit identification code, chassis number, or 17-digit number. Due to its unique identification of a vehicle, the VIN can be considered the vehicle's ID card.
