Are you starting a trucking business or planning to operate commercial vehicles across state lines? You’ll need a USDOT number—a critical requirement enforced by the Federal Motor Carrier Safety Administration (FMCSA). This unique identifier tracks your company’s safety records, compliance history, and more.
In this comprehensive guide, we’ll walk you through the entire process of getting your USDOT number, step-by-step, and answer some of the most frequently asked questions.
What Is a USDOT Number?
A USDOT number is a unique identifier assigned by the FMCSA (Federal Motor Carrier Safety Administration). It’s required for companies that operate commercial motor vehicles (CMVs) transporting passengers or hauling cargo in interstate commerce.
If your vehicle weighs over 10,000 lbs, transports hazardous materials, or carries more than 8-15 passengers for compensation, you must have a USDOT number.
Who Needs a USDOT Number?
You are required to obtain a USDOT number if:
-
Your commercial vehicle operates across state lines (interstate).
-
You transport hazardous materials.
-
Your vehicle has a gross vehicle weight rating (GVWR) of 10,001 pounds or more.
-
You carry 8 or more passengers for compensation or 15 passengers not for compensation.
-
Your state requires it for intrastate operations (e.g., Texas, Florida, California, etc.).
How to Get a USDOT Number: Step-by-Step
Determine Your Operating Authority
Before registering, identify whether you also need an MC number (Motor Carrier authority) in addition to a USDOT number. If you’re hauling for-hire or across state lines, both may be required.
Create a FMCSA Portal Account
Go to the FMCSA Registration website and create an account in the Unified Registration System (URS).
Complete the MCS-150 Form
The MCS-150 form collects details about your business, including:
-
Company name and address
-
EIN or SSN
-
Vehicle and operation types
-
Number of drivers
-
Insurance information
Submit Your Application
Once the form is completed, submit it through the FMCSA’s online portal. Your USDOT number is issued immediately upon successful submission.
Display the USDOT Number
After receiving your number, display it on both sides of your commercial vehicle using at least 2-inch-tall lettering that contrasts with the vehicle’s color.
