On February 25, 2026 By newsroom Topic: Automotive

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.
