How Many Digits Does a Car Engine Number Have?

[McGideon]

Car engine numbers typically range between 7 to 8 digits, varying by manufacturer. The engine number is part of the VIN (Vehicle Identification Number), a unique alphanumeric code assigned by the manufacturer to identify a specific vehicle. A VIN consists of 17 characters (letters and numbers), also known as the 17-digit identification code or chassis number. Through combinatorial arrangement, this system ensures no duplicate numbers occur within the same vehicle model for 30 years, granting each car a unique identifier – essentially serving as its "ID card". The engine number is usually stamped on the engine block; it can be found by opening the hood, though exact locations differ among manufacturers and may require consulting the vehicle's manual.
