Infiniti VIN, Engine and Model Decoding

What is a VIN?
The VIN is the "Vehicle Identification Number" for your automobile or truck. This number breaks down your vehicle to illustrate such things as engine size, body style, model year, transmission type, color, etc. For vehicles newer than 1980, this is a 17 digit alphanumeric number.

Where to Find VIN Numbers?
The most common place to find your VIN (Vehicle Identification Number) is on a small metal plate attached to the driver side top of the dashboard. The tag is designed to be visible through the windshield for easy access. Every car is required to have one of these and all of them are located in this one place. It is illegal to remove or change this plate. If the tag is missing, chances are the vehicle has been repaired, or was most likely, stolen.

Other places where you might find your vehicles' VIN number:

  • Vehicle Identification Label in your Owner's Manual
  • Stamped on the frame under the front hood
  • On a sticker on the driver's side door pillar
  • On state vehicle registration certificate
  • On the vehicle title of ownership
  • New cars have the VIN on the price sticker
  • A label in the luggage/spare tire area

Why is this VIN so important?
The VIN gives a detailed breakdown of your vehicle so any guesswork on the application of the vehicle to find the correct parts, repair information, service procedures, etc.

Are all the letters and numbers necessary when entering my VIN?

Yes, the VIN sequence as well as properly entering each number and letter is critical. Each alphanumeric entry represents a particular feature of your vehicle so please take your time while entering the VIN and double-check it.
