What Is a VIN?
A Vehicle Identification Number (VIN) is a unique 17-character alphanumeric code assigned to every car sold in the U.S. since the 1980s. It provides crucial information about a car's manufacturing details, safety features, and history.
- Format:
- The VIN does not include the letters I, O, or Q to avoid confusion with the numbers 1 and 0.
- Found on a metal plate in locations like the dashboard (visible through the windshield), the driver’s-side doorjamb, or on documents like the title and registration.
What Can a VIN Tell You?
1. Vehicle Specifications
- Assembly Details: Where and when the vehicle was made.
- Engine and Transmission: The eighth digit identifies the engine type, and other digits may provide further mechanical details.
- Trim Level and Features: Confirm safety features (e.g., automatic emergency braking, lane assist) or options included in the car’s build.
2. Recall Information
- Use the VIN to check for open recalls (free repairs for safety defects) on sites like the NHTSA’s recall page.
- Some dealerships may also check recall status for you.
3. Vehicle History
- Access service records, if available.
- Use services like CarFax or AutoCheck for crash history, previous owners, rental use, or salvage titles.
4. Theft or Salvage Status
- Check the National Insurance Crime Bureau’s VINCheck tool to see if a car has been stolen or issued a salvage title due to major damage.
