Free NHTSA VIN Decoder
Decode any 17-character VIN in seconds using the official NHTSA vPIC database. No signup, no usage limits.
Need this in production, at scale?
The public NHTSA endpoint is perfect for testing. When your app needs <200 ms latency, 99.95% uptime, SLA, and OEM catalog enrichment, integrate our commercial API.
Why this decoder
Official NHTSA data
We call vpic.nhtsa.dot.gov directly — the same data insurers and US regulators rely on.
100% free, no login
No signup, no credits, no captcha. Ideal for validating a one-off VIN or learning WMI/VDS/VIS structure.
Private
The request goes from your browser to NHTSA. We don't store the VIN or the results.
Frequently asked questions
Is the NHTSA VIN decoder really free?
Yes. The National Highway Traffic Safety Administration (NHTSA) publishes the vPIC API publicly and free of charge, with no documented query limit. This tool calls that endpoint directly from your browser.
How accurate is the NHTSA VIN decoder?
NHTSA is the official regulatory source in the United States. It's highly accurate for make, model, year, plant, and technical specs (engine, transmission, chassis). It does NOT include ownership history, accidents, or service records.
Does it work with VINs from Latin America, Europe, or Asia?
NHTSA decodes any standard ISO 3779 17-character VIN, including European, Japanese, and Latin American vehicles sold formally. The most detailed data is for vehicles commercialized in the US market.
How is this different from a commercial VIN decoder API?
NHTSA covers basic technical vehicle data. A commercial API like EITS adds OEM catalog enrichment (part numbers by VIN), SLA with <200 ms latency, 24/7 support, and optional equipment data that NHTSA doesn't expose.
Can I use this decoder in my app or site?
For one-off use or demos, you can call vpic.nhtsa.dot.gov directly. For production we recommend an API with SLA and caching — the public NHTSA endpoint doesn't guarantee uptime or latency under load.
