Commercial motor vehicles (CMV) are an essential part of the transportation industry, and with that comes certain regulations and requirements.

One of these requirements is obtaining a US Department of Transportation (DOT) number, a unique identifier assigned to commercial vehicles for monitoring safety information and compliance with federal regulations.

Obtaining a USDOT number can be confusing, especially for those new to the transportation industry. However, getting the application process right is crucial to avoid penalties and ensure regulatory compliance.

In this ultimate guide, we will break down the DOT registration steps, walk you through a complete FMCSA application process, and provide expert tips to ensure you file your USDOT number application correctly.

What Is a USDOT Number, and Why Do You Need It?

A USDOT number is a unique identifier assigned by the Federal Motor Carrier Safety Administration (FMCSA). It’s used to monitor and collect safety information on companies that operate commercial motor vehicles involved in interstate commerce.

Operating without a USDOT number when required can result in severe penalties, including fines and even being ordered to cease operations.

USDOT Number vs MC Number: What’s the Difference?

An MC number (Motor Carrier number), also known as Interstate Operating Authority, is a unique identifier for companies that operate in interstate commerce and transport regulated commodities for hire.

Without an MC number, businesses cannot legally transport goods or passengers across state lines for compensation. This includes both freight carriers and passenger carriers, as well as companies transporting household goods.

While a USDOT number tracks safety information, the MC number specifically authorizes a company to engage in for-hire transportation of regulated goods or passengers.

Step 1: Determine If You Need a USDOT Number or an MC Number

It is essential to determine if your business requires a USDOT number or an MC number before starting the application process. This will save you time and prevent any delays with obtaining the necessary operating authority.

According to the FMCSA, the following are required to obtain a USDOT number:

• Interstate Carriers: Companies that operate across state lines, transporting cargo or passengers.
• Intrastate Hazardous Materials Transporters: Companies operating within a state that transport hazardous materials that require placards.
• Commercial Vehicle Operators: Businesses using vehicles with a gross vehicle weight rating (GVWR) of 10,001 lbs or more are designed to carry more than eight passengers (including the driver) for compensation.
• For-Hire Carriers: Companies that transport passengers to the public for a fee.

On the other hand, businesses that typically need an MC number include:

• For-Hire Carriers: Companies that transport passengers or cargo for a fee across state lines.
• Freight Carriers: Businesses transporting regulated commodities across state lines.
• Passenger Carriers: Companies offering interstate transportation of passengers for compensation.
• Brokers: Entities that arrange for the transportation of goods but don’t operate trucks or cargo directly.

Tip: Use the FMCSA Registration website to check if you need an MC number, USDOT number, or both.

Step 2: Gather the Required Information for USDOT and MC Number Application

Before starting the application process, gather the essential details:

• Company information: Legal name, DBA (if applicable), and employer identification number (EIN) or social security number.
• Business structure: Sole proprietorship, corporation, LLC, etc.
• Business operation classification: Are you an interstate or intrastate carrier? Are you transporting property, passengers, or hazardous materials?
• Vehicle information: Number and type of commercial vehicles, gross vehicle weight (GVW), and whether your vehicles carry hazardous materials.

Step 3: Register Through the FMCSA Website

To register for a USDOT number, visit the FMCSA website and select “Portal Login”:

• Create an Account: If you don’t have an FMCSA account, you will need to create one by providing your email address and password.
• Select Your Registration Type: Select “USDOT Number Registration” from the drop-down menu and follow the prompts to enter your business information and complete registration.
• Pay the Application Fee (if applicable): The filing fee can be paid by credit card or electronic check (ACH).

Step 4: Complete Additional Compliance Steps

Depending on your business operation, you may need to complete additional compliance steps before receiving your USDOT and/or MC number. These may include:

• BOC-3 Filing: You must designate a process agent to handle legal documents in the states where you operate. This is required for the MC number and can be done through an FMCSA-certified BOC-3 filing agent.
• Insurance Filings: Businesses operating commercial motor vehicles must provide evidence of financial responsibility by filing proof of insurance with the FMCSA.
• Unified Carrier Registration (UCR): Companies that operate interstate are required to register and pay an annual fee based on fleet size through the UCR program.

Step 5: Review, Submit, and Wait for Confirmation

Before submitting your application for a USDOT or MC number, it’s important to conduct a final review to ensure that all information is accurate and complete.

After submitting your application, you will receive a USDOT and/or MC number confirmation via email:

• USDOT Number: If you’ve applied for a USDOT number only, it will be issued immediately after submitting your application. You can begin using your USDOT number right away.
• MC Number: The MC number undergoes a 21-day vetting period before it becomes active. During this time, the FMCSA will provide further instructions if any additional steps are needed, such as insurance filing or other compliance tasks.

You can check the status of your application on the FMCSA website using your USDOT or MC number.

Common Mistakes to Avoid When Filing for a USDOT Number Businesses often

Businesses make a few common errors when filing for a USDOT number. These can lead to delays in approval, additional fees, or even legal issues down the line. Here are some common mistakes to avoid when applying for your USDOT number:

• Incorrect Classification of Your Business: It’s essential to determine your business’s correct classification before applying for a USDOT number. For example, companies often misclassify themselves as intrastate (operating within one state) when they are actually engaged in interstate commerce.
• Missing or Inaccurate Information: Failing to provide accurate information on your application can result in delays or rejection. For example, your fleet mileage must be reported accurately, as it directly affects your compliance with federal regulations and safety requirements.
• Applying for the Wrong Type of Number: Some businesses mistakenly believe they need an MC number and a USDOT number when not all operations require it. Only those engaging in interstate commerce or transporting hazardous materials, regardless of whether they operate interstate or intrastate, need both. Use the FMCSA Registration website to confirm if your operation requires an MC number before starting the application process.
