Decoding The VIN Digits

A Vehicle Identification Number (VIN) is a unique combination of letters and numbers that acts as a vehicle’s fingerprint. No two vehicles have the same VIN. For auto dealers, understanding what each character represents is essential. Let’s break it down:

How Is a VIN Structured?

A VIN is made up of 17 characters, divided into three sections. Each section has specific information:

Section 1: World Manufacturer Identifier (WMI)

The first three characters of the VIN identify the vehicle’s origin and manufacturer.

• 1, 4, 5: Made in the United States
• 2: Made in Canada
• 3: Made in Mexico
• 6, 7: Made in Oceania
• 8, 9: Made in South America
• A-H: Made in Africa
• J-R: Made in Asia
• S-Z: Made in Europe

The second and third characters specify the manufacturer. Here are a few examples:

• B, C, D: Chrysler/Dodge
• FA, FB, FC, FD, EM, ET: Ford
• G: General Motors
• J4: Jeep
• L: Lincoln USA
• ME: Mercury USA
• P3: Plymouth USA
• YV: Mazda USA (Auto Alliance)
• ZV: Ford (Auto Alliance)

Section 2: Vehicle Descriptor Section (VDS)

This section consists of characters 4 through 9. Manufacturers use their own coding system here, but the breakdown generally looks like this:

• 4th-8th Characters: Represent the vehicle’s brand, engine size, and type.
• 9th Character: A security code that verifies the VIN’s authenticity.

Section 3: Vehicle Identifier Section (VIS)

This section, characters 10 through 17, provides specific details about the individual vehicle.

• 10th Character: Indicates the vehicle’s model year.
• 11th Character: Identifies the assembly plant where the vehicle was manufactured.
• 12th-17th Characters: A unique serial number assigned to the vehicle.

Where Can You Find the VIN?

For most standard passenger vehicles, the VIN is located in several common areas:

1. Dashboard (Driver’s Side): Stand outside the car and look at the corner of the dashboard where it meets the windshield.
2. Engine Block: Open the hood and look at the front of the engine block.
3. Driver’s Side Door Post: Check the area where the door latches when closed.
4. Front End of the Car’s Frame: Common for older vehicles.

If you’re unable to locate the VIN on the vehicle itself, check your insurance card, policy documents or the vehicle’s title.

Why Is the VIN Important?

A VIN serves many purposes:

• For Owners: It’s essential for vehicle titling and verifying details.
• For Mechanics: They use it to identify the correct parts for repairs.
• For Automakers: It’s critical for sending recall notices.
• For Dealers: The VIN is vital for inventory management and checking a vehicle’s history for accidents, thefts, or other issues. It’s also used to confirm if a warranty is still valid.

By understanding the significance of each character in a VIN, you unlock a wealth of information about a vehicle. Whether you’re buying, selling, or maintaining a car, knowing how to decode the VIN can save time and ensure you’re well-informed.
