Frequently Asked Questions
General VIN Information
What is a Vehicle Identification Number (VIN)?
A Vehicle Identification Number (VIN) is a unique 17-character code that serves as a vehicle's fingerprint. It contains information about the vehicle's manufacturer, specifications, and features. No two vehicles in operation have the same VIN.
Where can I find my VIN?
Your VIN can be found in several locations: driver's side dashboard (visible through windshield), driver's side door jamb, vehicle registration documents, insurance card, and sometimes on the engine block or frame.
Why is my VIN important?
Your VIN is crucial for vehicle identification, maintenance, recalls, and registration. It's used to identify correct parts, verify vehicle authenticity, and ensure proper maintenance.
VIN Decoding
What information can I get from a VIN decoder?
Our VIN decoder uses the National Highway Traffic Safety Administration (NHTSA) database to provide information including: manufacturer details, model year, assembly plant, vehicle type, engine specifications, transmission type, body style, and safety features.
How accurate is VIN decoding?
Our VIN decoding system uses the official NHTSA database to provide accurate information. While we strive for accuracy, some very new models or rare vehicles might not be immediately available in the database.
Can I decode any vehicle's VIN?
Our decoder works with vehicles registered in the NHTSA database. This includes most vehicles manufactured after 1981. Some limitations may apply to very new models or vehicles not registered in the US.

Technical Questions
What if my VIN isn't 17 characters?
Vehicles manufactured before 1981 may have VINs of varying lengths. The 17-character standardized VIN was implemented globally in 1981. Our validator can verify modern 17-character VINs using the NHTSA standard.
Why can't some VINs be decoded?
Some VINs may not decode properly if they're not registered in the NHTSA database. This can happen with: international vehicles not registered in the US, very new models not yet in the system, or vehicles manufactured before 1981.
What is a VIN check digit?
The check digit is a mathematical calculation used to verify the accuracy of a VIN. It's located in the 9th position of the VIN and helps prevent fraud and errors in VIN recording. Our tools use the NHTSA standard for check digit validation.
