When buying a used car, understanding its true history starts with one key detail: the Vehicle Identification Number (VIN). This 17-character code might look random, but it actually holds a wealth of information—if you know how to read it.
A VIN decoding chart makes it easier to break down this code line by line. In this guide, we’ll walk you through each section of the VIN, explain how to use a decoding chart, and help you avoid hidden surprises in your next vehicle purchase.
Why VINs Matter—and Why You Should Decode One
The Problem: You can’t always trust what’s on the for-sale listing. Sellers might hide accident history, swap badges, or misrepresent trim levels.
The Stakes: If you don’t decode the VIN, you could end up buying a car with a flood title, incorrect features, or even one that was stolen or rebuilt.
The Solution: Learning how to decode a VIN puts you back in control. A VIN decoding chart helps you identify the manufacturer, model, engine, and more—before you spend a dime.
What Is a VIN Decoding Chart?
A VIN decoding chart is a reference tool that helps interpret the meaning behind each character or section of a VIN. Every car built after 1981 has a 17-character VIN that follows a globally standardized format.
Each part of the VIN points to a specific detail:
- Where the car was built
- Who made it
- What engine and body type it has
- When it was made
- And more
Think of it like a barcode that tells the story of the car’s identity.
How to Read a VIN Number (Breakdown by Section)
Let’s break the VIN into key sections. Use the chart below to decode each part:
Positions 1–3: World Manufacturer Identifier (WMI)
Tells you where and by whom the vehicle was built.
| Character | Description | Example |
| 1 | Country of Origin | 1 = USA, J = Japan, K = Korea |
| 2 | Manufacturer | H = Honda, T = Toyota, V = VW |
| 3 | Vehicle Type/Division | G = Passenger car, T = Truck |
Positions 4–8: Vehicle Descriptor Section (VDS)
Describes the vehicle’s key features.
| Character | Description | Example |
| 4 | Model/Trim | A = Base, B = Sport, C = Touring |
| 5 | Body Style | 2 = 2-door, 4 = 4-door, W = Wagon |
| 6 | Engine Type | 1 = 1.5L, 2 = 2.0L Turbo, 3 = V6 |
| 7 | Restraint System | A = Front airbags, B = Front/Side |
| 8 | Transmission | M = Manual, A = Automatic, C = CVT |
Position 9: Check Digit
This is a security code used to prevent fraud. It’s calculated using a specific formula and ensures the VIN is valid—not made up or altered.
| Character | Description |
| 0-9 or X | Mathematical check to prevent fake VINs |
Position 10: Model Year
Indicates the production year, not always the same as the sale year.
| Character | Year |
| A | 2010 |
| B | 2011 |
| M | 2021 |
| N | 2022 |
| P | 2023 |
Position 11: Assembly Plant
Tells you where the car was assembled. Each manufacturer uses different codes (e.g., “K” might mean Kansas City for Ford vehicles).
| Character | Plant Location |
| A | Detroit, MI |
| B | Tokyo, Japan |
| C | Ontario, Canada |
Positions 12–17: Serial Number
These digits are unique to each vehicle. They don’t follow a universal standard but are used by the manufacturer to track production.
| Characters | Description |
| 12-17 | Unique serial number for each vehicle |
Example of VIN Breakdown
- 1HG = USA, Honda, Passenger Car
- CM826 = Accord Sedan EX V6 Automatic
- 3 = Check Digit
- 3 = Model Year 2003
- A = Plant in Marysville, OH
- 004352 = Unique Serial Number
This is a perfect example of how a car VIN decoder can bring everything together.

Why This Matters Before You Buy
A VIN decoding chart won’t just help you understand what you’re buying—it can also alert you to red flags:
🚩 The VIN says 2022, but the seller claims it’s a 2024? Walk away.
🚩 VIN shows 4-cylinder, but the car has a V6 badge? Possible engine swap.
🚩 Check digit is wrong? The VIN might be fake.
Decoding takes just a minute and gives you the upper hand in spotting lies, scams, or shady listings.
