What Is a USDOT Number?

A USDOT number is a unique identifier assigned by the Federal Motor Carrier Safety Administration (FMCSA) to commercial motor carriers. It is used to monitor safety practices, conduct audits, and track compliance with federal safety regulations through the company’s safety information acquired.

Who Needs a USDOT Number for Interstate Commerce?

You must obtain a USDOT number if you operate a vehicle that meets any of the following criteria:

• Vehicles over 10,000 lbs. (Gross Vehicle Weight Rating – GVWR) used in interstate commerce.

• Transporting hazardous materials that require placarding.

• Vehicles designed to transport more than 8 passengers (for compensation) or more than 15 passengers (not for compensation).

• Operating as a for-hire carrier (paid to transport goods or passengers).

Most commercial trucking companies, passenger transport services, and hazardous material carriers must register for a USDOT number.

Determining if You Need a DOT Number

Determining whether your business operation requires a DOT number involves evaluating several critical factors. Here are the key points to consider:

• Interstate Commerce: If your company operates commercial vehicles that transport passengers or cargo across state lines, you are engaged in interstate commerce and must obtain a DOT number. This is crucial for regulatory compliance and safety monitoring.

• Gross Vehicle Weight Rating (GVWR): If your vehicles have a gross vehicle weight rating (GVWR) of 10,001 pounds or more, you need a DOT number. This requirement applies regardless of whether you operate in interstate or intrastate commerce.

• Hazardous Materials: Companies that transport hazardous materials requiring a safety permit must obtain a DOT number. Compliance with hazardous materials regulations is essential for ensuring safe transportation and avoiding penalties.

• Passenger Capacity: If your vehicles are designed to transport more than eight passengers, including the driver, for compensation, you are required to have a DOT number. This ensures that passenger transport services adhere to federal safety standards.

• Operating Authority: If you plan to operate as a for-hire carrier in interstate commerce, you will likely need to obtain operating authority in addition to your USDOT number. This is necessary for legal operation and compliance with federal regulations.

By considering these factors, you can determine whether your business operation requires a DOT number and take the necessary steps to comply with federal regulations.

Eligibility Requirements

To determine if your business operation requires a USDOT number, you must meet specific eligibility requirements. These requirements are based on the type of commercial vehicles you operate, the weight of your vehicles, and the type of cargo you transport.

• Gross Vehicle Weight Rating (GVWR): If your commercial vehicle has a GVWR of 10,001 pounds or more, you are required to obtain a USDOT number.

• Gross Combination Weight Rating (GCWR): If your commercial vehicle has a GCWR of 10,001 pounds or more, you are required to obtain a USDOT number.

• Interstate Commerce: If you operate in interstate commerce, you are required to obtain a USDOT number.

• Hazardous Materials: If you transport hazardous materials, you are required to obtain a USDOT number.

• Passengers: If you transport more than eight passengers (including the driver) for compensation, you are required to obtain a USDOT number.

• Operating Authority: If you plan to operate as a for-hire carrier in interstate commerce, you will likely need your Operating Authority in addition to obtaining a USDOT number.

Understanding these eligibility requirements is crucial for ensuring your business complies with federal regulations and operates smoothly.

Step-by-Step Guide to Getting a USDOT Number

Step 1: Determine Your Registration Requirements

Before applying, determine whether you need:

• A USDOT Number only

• Operating Authority (MC Number) in addition to a USDOT Number (required for for-hire carriers in interstate commerce)

You can check FMCSA’s registration tool here to confirm your requirements.

Step 2: Gather Required Information

Before starting your application, have the following details ready:

• Company Name & Business Type

• Employer Identification Number (EIN) or Social Security Number (SSN)

• Company Address & Contact Information

• Type of Business Operation (e.g., Private Carrier, For-Hire, Exempt)

• Vehicle Information (number of vehicles, weight, cargo type, etc.)

• Hazardous Materials (if applicable)

• Driver Information (number of drivers, CDL holders, etc.)

Step 3: Apply Online Through FMCSA’s Unified Registration System (URS)

All applications for USDOT numbers must be submitted through the FMCSA Unified Registration System (URS).

How to Apply:

1. Go to the FMCSA Registration Page: https://www.fmcsa.dot.gov/registration

2. Click on “New Applicant” and follow the instructions.

3. Create a login with Login.gov (if you don’t already have an account).

4. Complete the online USDOT application with your company details.

5. Pay any applicable fees (if applying for additional authority like an MC number).

6. Submit the application and save your confirmation number.

Important: There is no fee for obtaining a USDOT number, but there are fees if you are also applying for an MC Number (Operating Authority).

Step 4: Wait for USDOT Number Assignment

• Once you submit your application, your USDOT number is issued immediately.

• If you applied for additional operating authority (MC Number), processing times may take several weeks.

Step 5: Display Your USDOT Number

Once assigned, your USDOT number must be displayed on your commercial vehicle.

Requirements for Displaying the USDOT Number:

• Must be clearly visible on both sides of the vehicle.

• Lettering must be at least 2 inches high and in a contrasting color.

• Include “USDOT” followed by your number (e.g., USDOT 1234567). This number is crucial as it is used by the FMCSA to gather and monitor a company’s safety information acquired during various regulatory activities, such as roadside inspections and audits.

Step 6: Additional Considerations for Heavy Vehicles

When operating heavy vehicles, there are additional considerations to keep in mind to ensure compliance with federal regulations:

• Gross Combination Weight Rating (GCWR): If your vehicles have a gross combination weight rating (GCWR) of 10,001 pounds or more, you are required to obtain a DOT number. This applies to combinations of vehicles, such as a truck and trailer, where the combined weight meets or exceeds this threshold.

• Commercial Vehicles: Operating commercial vehicles that transport passengers or cargo necessitates compliance with federal regulations, including obtaining a DOT number. This ensures that your business adheres to safety standards and regulatory requirements.

• Safety Information: A DOT number allows regulatory authorities to monitor your company’s safety information acquired during roadside inspections, audits, compliance reviews, and crash investigations. This data is crucial for maintaining safety standards and avoiding penalties.

• Hazardous Materials Regulations: If you transport hazardous materials, you must comply with hazardous materials regulations and obtain a DOT number. This includes adhering to specific safety protocols and obtaining the necessary permits.

• Registration Process: The registration process for a DOT number involves creating an FMCSA account, selecting an operator classification, and providing required documents, such as your Employer Identification Number (EIN) or Social Security Number. Ensuring all information is accurate and complete is essential for a smooth registration process.

By understanding these additional considerations, you can ensure that your heavy vehicles comply with federal regulations and operate safely and legally.

Step 7: Maintain Compliance with FMCSA and Hazardous Materials Regulations

If your company operates commercial motor vehicles requiring a CDL, you must comply with DOT drug and alcohol testing regulations.

This includes:

✔ Pre-employment drug testing

✔ Random drug & alcohol testing

✔ Post-accident, reasonable suspicion, and return-to-duty testing

Focused Compliance Group can help you set up and manage your DOT drug testing program to stay compliant.

Step 7: Maintain Compliance with FMCSA Regulations

Once you have your USDOT number, you must follow FMCSA safety regulations, including:

• Biennial Updates: Update your information every 2 years via the FMCSA MCS-150 form.

• Driver Qualification Files: Maintain records of driver medical exams, CDL history, and training.

• Hours of Service (HOS) Compliance: Track and log driver work hours.

• Vehicle Inspections & Maintenance: Perform routine maintenance and keep records.

Failing to maintain compliance can result in fines, penalties, or revocation of your USDOT number.

Understanding the Costs and Timeline

Obtaining a USDOT number is a relatively straightforward process, but it’s essential to understand the costs and timeline involved.

• Cost: There is no cost to obtain a USDOT number. However, you may need to pay for additional services, such as operating authority and permits.

• Timeline: The registration process can take a few hours to complete. You will need to create an FMCSA account, select and enter a password, answer three security questions and answers, and complete the application.

• Documents: You will need to provide specific documents, including your Employer Identification Number (EIN) or Social Security Number, Dun & Bradstreet Number, and names and titles of all company officers.

By understanding the costs and timeline, you can better prepare for the registration process and ensure a smooth application experience.
