What Is a USDOT Number?
A USDOT number is your carrier's unique identifier in the US Federal Motor Carrier Safety Administration (FMCSA) system. It tracks your safety record, inspections, compliance reviews, crash data, and insurance status. The number follows the format USDOT XXXXXXX (7-8 digits). Every commercial vehicle operating in the US with a GVWR over 10,001 lbs (4,536 kg) may need one.
How Much Does a DOT Number Cost?
The USDOT number itself is free — there is no fee to register with FMCSA. However, if you need MC (Motor Carrier) operating authority for for-hire operations, the filing fee is $300 USD. Additional costs include BOC-3 process agent designation ($30-$100 USD) and insurance meeting FMCSA minimums ($750,000 liability for general freight, the current corporate maximum for hazmat). Vehicle marking (USDOT decals) costs $29.99-$89.99 depending on the package.

How to Apply — Step by Step
Register online through the FMCSA Unified Registration System at safer.fmcsa.dot.gov. Select 'Foreign Motor Carrier' as your carrier type. Provide your Canadian business information, vehicle details, commodities transported, and operational scope. Processing takes 1-3 business days. Once approved, your USDOT number is active immediately — mark your vehicles before your first US trip.
USDOT Marking Requirements
Under 49 CFR 390.21, your USDOT number should be permanently displayed on both sides of the power unit. Legible from 50 feet (15 metres) in daylight, in a colour contrasting the vehicle surface. Include your legal carrier name and MC number (if applicable).
Biennial Update Requirement
You must update your USDOT registration every two years, even if nothing has changed. Failure to complete the biennial update results in deactivation of your USDOT number. Check your update due date on the FMCSA SAFER system. You can update online at safer.fmcsa.dot.gov.
Canadian + US Dual Requirements
Canadian carriers need to keep provincial carrier documentation current and display the US markings that FMCSA requires when operating in the United States. For Ontario carriers, that means CVOR documentation and any source-checked fleet ID you choose, plus USDOT number, MC number where applicable, and carrier name for covered US operations. Our Cross-Border Trucking Kit keeps those identifiers separated by jurisdiction.
