A USDOT Number, mandated by the Federal Motor Carrier Safety Administration (FMCSA), is a requirement for commercial vehicles involved in interstate commerce. Its primary purpose is to enforce safety standards, monitor compliance, conduct audits, and ultimately enhance road safety. Non-compliance with these regulations can lead to significant penalties, including substantial fines and potentially even suspension of the authority to operate.

This guide will walk you through the process of obtaining a USDOT Number and the possible negative outcomes your business could confront if it doesn't comply with these regulations.

What Exactly is a DOT Number and What is Its Purpose

A DOT Number, specifically known as a USDOT number when issued by the Federal Motor Carrier Safety Administration, serves as a unique identifier for commercial vehicles operating in interstate commerce or carrying hazardous materials. This number is crucial for enforcing adherence to safety regulations and protocols across the transportation industry, and it’s mandatory for certain types of trucks. By tracking compliance, conducting audits, and facilitating inspections, the USDOT number helps ensure that fleet operators maintain high safety standards, thus safeguarding public roads.

How To Get a USDOT Number

As we mentioned before, obtaining a USDOT Number is an essential step for companies operating commercial vehicles that engage in interstate commerce or transport hazardous materials. To get it, you’ll need to follow these steps:

  1. Verify that your business requires a USDOT Number. Motor carriers are required to complete USDOT registration if they are engaged in interstate travel and operate vehicles weighing more than 10,000 pounds, transport 9 to 15 passengers (including driver) for compensation, transport 16 or more passengers (including driver) not for compensation, or transport hazardous materials.
  2. Go to the FMCSA registration portal at FMCSA Registration to fill out the Motor Carrier Identification Report (MCS-150) and the Combined Identification and Hazardous Materials Safety Permit Application, if applicable.
  3. Pay required fees. While the USDOT Number itself is free, there may be fees associated with obtaining operating authority or other specific licenses. For instance, if you require an additional MC number, you would need to pay a $300 registration fee for it.
  4. Update your USDOT Number registration information every two years or whenever there are changes to your company information, such as address, number of vehicles, ownership, or if the company ceases interstate operations.

What Is The Difference Between USDOT Numbers and MC Numbers?

The primary difference between USDOT numbers and MC numbers is their unique roles within the transportation industry. The US Department of Transportation assigns a USDOT number as an interstate operating authority for all commercial vehicles transporting goods or passengers across state lines.

On the other hand, the Federal Motor Carrier Safety Administration (FMCSA) provides an MC number. This number is an additional form of interstate operating authority specifically needed for moving companies that transport passengers or federally regulated commodities across state lines. While all interstate movers must display an active USDOT number, not all moving companies require an MC number, making it a specialized requirement for certain types of interstate carriers.

Checking If Your USDOT Number Is Active

If you are unsure about the status of your USDOT Number, you can search for your company’s information inside the FMCSA website. Here’s how to do it:

  1. Visiting the FMCSA System website.
  2. Input your USDOT Number into the search field provided on the SAFER website. You’ll find it under the title “Search Passenger Carriers USDOT # or Company Name”
  3. The search result will include a snapshot of your company's information, where you can review the current status of your USDOT Number—active, inactive, or out of service.
