USDOT Numbers are used by the USDOT to monitor a company or independent owner-operator's safety management practices and controls. They serve as unique identifiers when the USDOT collects data and reviews a company's compliance during safety audits, compliance reviews, crash investigations, and roadside inspections. This is not "Operating Authority" (MC Number). Click to get an Interstate USDOT Number.
DOT Number Requirement
Companies that operate commercial motor vehicles that transport passengers or haul cargo across state lines in vehicles over 10,000 lbs must be registered with the USDOT and must display an "Interstate USDOT Number" on their vehicles. Companies operating within most states must have an "Intrastate USDOT Number" unless they have secured state-issued operating authority. $300 service fee applies.
