Is a USDOT Number Free? What It Costs, and What You Actually Pay For
Yes. FMCSA doesn't charge a fee for a USDOT number. If a website asks you for hundreds of dollars "for your DOT number," you're paying a private company for its service, not a government fee. That can be fine, but you should know which is which.
Who needs a USDOT number
Under federal rules, you need one if you operate in interstate commerce with a vehicle that:
- Has a gross vehicle weight rating or combination weight of 10,001 lbs or more
- Is designed or used to carry 9 or more passengers (including the driver) for compensation
- Is designed or used to carry 16 or more passengers (including the driver) not for compensation
- Carries hazardous materials in amounts that require placards
Many states also require a USDOT number for trucks that never leave the state. Not sure what applies to you? Our free compliance check tells you in a few questions.
Where the real costs are
