Originally, engine numbers were created as serial numbers and they remain so. The manufacturers imprint the numbers on the engine block, a part of the engine that cannot be removed easily.

On the engine tag, there are nine characters. A three-digit engine code comes first, and a six-digit number follows. You can also check your owner’s manual for the engine number if you cannot locate it on the engine.

As mentioned earlier, it is a vital number to have handy for routine maintenance of your car and in case you need to replace an engine part. Paired with a VIN, it helps manufacturers track cars for fixing an issue or recall cars.

The engine ID tag contains the specifications of your engine (in the code number), the model, make, and year of manufacture. Some cars like FORD also include the assembly plant of the engine.

On the engine, you can see it under the bolts of the engine, on its left or right side. Do not mix up the engine tag with the EPA tag.

Where Do You Find the Vin on an Engine?

A car’s Vehicle Identification Number (VIN) is also the chassis number of the car. Like a fingerprint, each car has a unique VIN. It is a code that details the manufacturing information, body style, and drive train of your car.

The VIN comprises 17 characters (letters and numbers), and the National Highway Traffic Safety Administration required it on every car from 1981. As the chassis number, it is on the chassis of the car. Other locations are:

  • The lower-left corner of the car’s dashboard. It is on a plate and you can see it from the windshield (easy for police checks.)
  • Your registration certificate.
  • The hood of your car.
  • Your insurance policy documents.
  • The doorpost of the driver’s side. Look for it close to where the door latch is, near the seatbelt return.
  • In front of the engine block. You easily see it once you pop your hood.
  • Inside the doorjamb on the driver’s side. It is situated where the side mirror would be if you shut the door.
  • Underneath the spare tire and also on the well of the rear wheel.
  • On the car frame, close to the can that holds washer fluid for the windshield.

How to Decode the Vin

Finding your car’s VIN is useless if you cannot decode or interpret it. You interpret it using this guide:

  • The first character tells the country your car was manufactured in. A VIN that begins with 1, 4, and 5 indicates US-made cars.
  • The second and third characters show details of the manufacturer.
  • The eighth number from the left shows the type of engine installed, its capacity, and the car’s fuel type.
  • The ninth number indicates the security code put by the manufacturer.
  • The tenth number from the left specifies the model year of the car (not the year it was built).
  • The manufacturing plant of your car’s model is the eleventh digit and the 6 numbers left is the serial number of the car.

This is a general pattern that manufacturers usually use. Different car manufacturers also have unique code manuals you can use to decode the VIN. 

The Importance of the Vin

There are many reasons the VIN is important, especially if you want to buy a second-hand car. Outlined below are the reasons:

  1. In track information about your car’s accident and insurance claim history
  2. Your car’s registration information is tied to it.
  3. It verifies the identity of the car and rules out suspicious activities surrounding the car.

There are many databases of VINS that enable a search and comparison. Some of these databases have limited free uses and others are paid platforms.
