Every vehicle has a unique identifier, like a fingerprint, known as a Vehicle Identification Number (VIN). This 17-character string of letters and numbers holds important details about your car’s origin, specifications, and history. Understanding how to decode your VIN can help verify authenticity, order parts, and even check its history for recalls or accidents. In this blog, we’ll discuss what each section of your VIN reveals and how to use this information to your advantage.
Breaking Down the VIN: What Each Section Means
A VIN is divided into three main sections:
World Manufacturer Identifier (WMI) – Characters 1-3
The first three characters of a VIN identify the vehicle’s origin and manufacturer:

- 2nd Character: Manufacturer Codesome text
- "T" – Toyota
- "H" – Honda
- "F" – Ford
- 3rd Character: Vehicle Typesome text
- It is used to describe if it’s a passenger car, SUV, or truck.
Example: A VIN starting with "1HG" means the vehicle was manufactured in the U.S. by Honda.
Vehicle Descriptor Section (VDS) – Characters 4-9
This section describes the vehicle’s specifications, such as:
- 4th-8th Characters: Model, engine type, body style, and transmission.
- 9th Character: Check Digit – Used to verify if the VIN is valid through a mathematical formula.
Example: "CM826" could indicate a Honda Accord with a 2.4L engine and automatic transmission.
