Free VIN Decoder: How to Read a VIN Number Like a Pro
Every vehicle on the road has a unique 17-character identifier that tells the complete story of where it was built, who made it, and exactly how it left the factory. A VIN decoder helps you read that story.
A Brief History of the VIN
The Vehicle Identification Number was standardized in 1981 by the National Highway Traffic Safety Administration. Before 1981, VINs varied wildly between manufacturers in length and format. Since 1981, every vehicle sold in the United States has used a standardized 17-character format regulated by ISO 3779 and NHTSA standards.
