Trucking and regulatory
USDOT number
A USDOT number is the unique identifier that FMCSA gives to a company that operates commercial vehicles. It is used to collect and monitor a company's safety information from audits, reviews, crash investigations and inspections. Federal rules decide who must register.
Why it matters
The USDOT number is the formal name of the DOT number most trucks show on the door. Companies that run commercial vehicles in interstate commerce must register with FMCSA and have one. Some intrastate hazmat carriers must too, and many states add their own rules. Applicants register online. A common mistake is to buy, sell or lease a number. FMCSA warns against that. Another is to let registration data go stale. Keep your contact details, vehicles and drivers updated. Use the FMCSA tool to see whether your trucks need a number, and check your state for intrastate rules.
