What Is a USDOT Number?
A USDOT number is a unique identifier the US Department of Transportation assigns to any commercial vehicle operator that hauls cargo or passengers across state lines. For auto transport, both brokers and motor carriers are required to have one (and carriers additionally need an MC number). It's your single best tool for verifying that a company is legitimate.
How to Look Up a USDOT Number
Go to safer.fmcsa.dot.gov and enter the USDOT or company name. You'll see: operating authority status (active/inactive), insurance on file, safety rating, total power units, out-of-service rate, and inspection history. Any broker or carrier without an active USDOT should not be trusted with your vehicle.
What to Look for in the FMCSA Record
Green flags: active authority, insurance on file, low out-of-service rate, multiple years of operating history. Red flags: 'not authorized' status, no insurance, brand-new authority (less than 6 months old for a company claiming to be established), or a pattern of name changes.
How AutoTransport AI Uses USDOT Data
Every carrier in our network is continuously monitored through the Highway platform, which pulls live FMCSA data. If a carrier's authority lapses, insurance expires, or their safety score drops, they're automatically removed from the assignable pool — before they can accept your load.
