What Is a Vehicle Identification Number (VIN)?

We’ve been around for over 200 years, helping customers with their car insurance needs. During this time, we’ve answered countless questions about vehicles and coverages. One that we hear a lot is, “What is a vehicle identification number?” A vehicle identification number (VIN) is a 17-character serial number used to uniquely identify a car. Think of it as a fingerprint, because no two VIN numbers are alike, even if the cars are the same make and model.
In order to get a car insurance policy through the
AARP® Auto Insurance Program from The Hartford,
1 you’ll need your car’s VIN number. Insurers use this to look up car records and help calculate car insurance rates.
Where Is the Vehicle Identification Number Located?
You can find your VIN number in four locations on your car:
-
The interior dashboard on the driver’s side
-
Under the hood
-
The front-end of the frame
-
Driver’s side door
You can also find the VIN number on your car’s:
- Título
- Registro
-
Auto insurance documents
Depending on when you bought your car, some dealerships also use VIN etching. This puts the number on each window and windshield to prevent theft.
How to Decode the Vehicle Identification Number
While your car’s 17-digit VIN may look like a random set of numbers and letters, there is a meaning behind each character.
The first three characters represent the world manufacturer identifier (WMI).
-
The first number or letter shows the country that assembled your car.
-
The second character relates to your car manufacturer.
-
When used with the first two characters, the third digit can identify your car type.
The next group of six characters describes your car.
-
Characters four through eight tell your car’s model, body type, transmission and engine.
-
Next is a “check digit,” which validates the VIN is real.
-
Then a letter that corresponds to a model year.
-
That’s followed by the plant code that put together your car.
-
The final six digits are numbers your car receives on the assembly line when it’s made.
