The NHTSA Product Information Catalog Vehicle Listing (vPIC) Application Programming Interface (API) provides different ways to gather information on Vehicles and their specifications. The vPIC Dataset is populated using the information submitted by the Motor Vehicle manufacturers through the 565 submittals. All the information on how a VIN is assigned by the manufacturer is captured in this catalog and used to decode a VIN and extract vehicle information.
For more information - National Highway Traffic Safety Administration. I have integrated this API with multiple fleet management systems. Copy and paste this VIN as a sample, or use any full VIN... JC1NFAEK2J0136343 NOTE: If results Error Text field does not equal "0", the results are invalid.
