What is VIN (Vehicle Identification Number)?
The Vehicle Identification Number (VIN) is a unique 17-character code (numbers and capital letters) used to identify individual motor vehicles. It serves as a car's fingerprint, as no two vehicles have the same VIN. The VIN provides essential details about the car, including its manufacturer, production year, manufacturing plant, and engine type.
VIN helps obtain detailed vehicle history reports, enhancing transparency and security in vehicle transactions.
Where to Find Your Vehicle's VIN?
VIN is typically found in the following areas:
• Dashboard: Visible through the windshield on the driver's side.
• Door Frame/Post: Located where the driver's side door latches.
• Engine Block: Stamped on the engine block.
• Vehicle Documents: Printed on vehicle registration, title, and insurance documents.
Always verify that the VIN on the vehicle matches the VIN on your documents to avoid discrepancies.
How VIN Decoders Work
Once you enter a VIN number into a decoder tool it divides the VIN into standardized segments.
The decoder separates the VIN into specific sections (WMI, VDS, Check Digit, Model Year, Plant Code, VIS).
The VIN's authenticity is verified using the check digit.
Each section is cross-referenced against databases to retrieve details such as manufacturer, model, year, and plant, recall and other information about your car.
Typical information provided by a VIN decoder includes:
• Manufacturer
• Model and body type
• Model year
• Engine specifications
• Manufacturing location
• Safety recalls
• Accident history
• Odometer records
• Previous vehicle usage
• Ownership and sales history
Check Digit Validation Explained
The check digit (9th character) validates the VIN through a mathematical formula. If the computed digit differs from the provided digit, the VIN is flagged as invalid, suggesting possible errors or fraudulent activity.
Example VIN Decoding Process
Using the VIN: 1HGCM82633A004352
• WMI: 1HG (Honda, USA)
• Vehicle Descriptor Section (VDS): CM826 (Accord model, coupe body)
• Check Digit: 3
• Model Year: 2003
• Plant Code: A (Marysville, Ohio)
• Vehicle indicator section (VIS): 004352 (serial number)
Decoder verifies the check digit and confirms against a database that it is indeed 2003 Honda Accord Coupe, manufactured in Marysville, Ohio.
Now that you have your VIN decoded, you can gain additional valuable information. For example, we now know that our Honda has had 10 recalls and other issues.
By clearly understanding this decoding process, you gain valuable insights, ensuring informed vehicle buying or selling decisions.
Role of Databases and Data Sources
VIN decoders rely on extensive databases sourced from vehicle manufacturers, insurance companies, regulatory bodies, and official government agencies. These databases ensure accuracy, comprehensiveness, and reliability of the information provided by VIN decoders.
At TrueVIN we're using data from more than 200 data providers to produce vehicle history reports.
Automated vs. Manual Decoding
Automated VIN decoding is preferred due to its speed, accuracy, and reduced potential for human error. While manual decoding is possible, it is often impractical due to complexity, time consumption, and the high likelihood of mistakes.
