Decoding a car’s VIN (Vehicle Identification Number) is essential for any car buyer, seller, or enthusiast. The VIN is a unique string of letters and numbers assigned to every vehicle, providing vital information about its history, specifications, and more. Understanding how to interpret this alphanumeric code can save you from bad investments and might even reveal hidden secrets about the vehicle’s past.
1. What is a VIN Number?
A VIN is a 17-character code that serves as a car’s unique identifier. It can be found on various parts of the vehicle, often visible through the windshield on the driver’s side dashboard or on the driver’s side door frame.
The VIN contains specific information about the vehicle, including its origin, manufacturer, model year, and engine size.
Each character in the VIN serves a purpose, making it a powerful tool for identifying vehicles.
2. Breaking Down the VIN: What Each Section Represents
A VIN is structured into three distinct sections:
WMI (World Manufacturer Identifier) – Characters 1-3
The first three characters represent the manufacturer and the country of origin.
- 1-3 Characters: Identifies the country (e.g. 1 is for the USA, 2 for Canada, J for Japan).
- 4-8 Characters: Identifies the vehicle characteristics including model, body style, engine type, etc.
VDS (Vehicle Description Section) – Characters 4-8
This part contains information on the vehicle’s model and body style.
- 4 Characters: Vehicle type (e.g., sedan, coupe).
- 5 Characters: Model designation.
- 6-8 Characters: Engine and transmission specifications.
Check Digit – Character 9
The ninth character is a check digit used to detect fraudulent VINs. It helps ensure that the VIN is correctly composed.
Model Year – Character 10
The tenth character signifies the model year of the vehicle. Characters can represent different years, cycling through letters and numbers:
- A = 1980, B = 1981, …, Y = 2000, 1 = 2001, 2 = 2002, …, 9 = 2009, A = 2010, B = 2011, and so forth.
Plant Code – Character 11
The eleventh character indicates the manufacturing plant that produced the vehicle.
Serial Number – Characters 12-17
The last six characters represent the unique serial number of each vehicle. This part is what differentiates one car from another.
3. How to Find Your Car’s VIN
If you’re looking to decode a VIN, the first step is finding it on your vehicle. Here are the common locations to check:

If you are purchasing a used vehicle, always verify the VIN on the car matches the one on the title and documentation!
4. Decoding the VIN: Step-by-Step
Once you have located the VIN, follow these steps to decode it:
