United States Vehicle Makes Directory
Every car, truck, motorcycle and trailer brand registered with US road safety regulators, with its official ID.
The official list of vehicle makes (brands) recognised by the US National Highway Traffic Safety Administration's Vehicle Product Information Catalog, each with a stable numeric make ID. It is the reference table behind VIN decoding, recall lookups and vehicle data normalisation. Insurers, auto marketplaces, fleet platforms and car-related AI agents use it to standardise messy brand names.
