The NHTSA Application Programming Interface (API) is being used by the dynamic search applications within the website, to deliver safety issues and rating information to the general public. This API is NOT meant to be used by any other applications to perform bulk VIN lookups.

Users/Applications attempting bulk VIN lookups will be controlled by an automated traffic rate control mechanism to ensure optimal performance of the NHTSA websites and minimize adverse impact to its users.

NHTSA will be continually updating the API to improve data access.

Please check back this section to obtain latest information on the API and API use policies.
