The trucking industry in the U.S. operates under strict regulations set by the FMCSA (Federal Motor Carrier Safety Administration). If you are starting a trucking company or already running one, you’ve likely encountered terms like USDOT and MC numbers. These identifiers play an important role in your company’s compliance with federal and state regulations. Whether you are transporting goods within your state or across state lines, understanding the difference between these two numbers is essential for your trucking business.
The USDOT number primarily tracks your company’s safety record, ensuring that both drivers and vehicles are up to federal safety standards. On the other hand, the MC number is your company’s ticket to legally transporting goods for hire across state lines. Without these vital identifiers, your business could face fines, delays, or even the suspension of your operating authority.
In this blog, we will break down the key differences between MC and USDOT numbers, their purposes, and why they are essential for your trucking business to stay compliant and operate smoothly.
What Is a USDOT Number?
A USDOT (U.S. Department of Transportation) number is a unique identifier issued by the FMCSA (Federal Motor Carrier Safety Administration) to all companies operating commercial motor vehicles (CMVs) involved in interstate commerce or transporting hazardous materials. This number is crucial for tracking safety-related information such as compliance with safety regulations, accident reports, and inspection results. The FMCSA uses this number to monitor the safety performance of motor carriers and ensure they meet federal safety standards.
Key Facts About USDOT Numbers:
- Required for Interstate Carriers and Hazardous Materials Transporters: If your trucking company operates across state lines or carries hazardous materials, obtaining a USDOT number is mandatory. This number ensures that your business is in compliance with both state and federal transportation laws.
- Tracks Company Safety Records: The USDOT number allows regulatory authorities to access your company’s safety performance data, including driver qualifications, vehicle inspections, and accident history. We regularly review this information to ensure companies adhere to safety regulations.
- Must Be Clearly Displayed on CMVs: The USDOT number must be prominently displayed on both sides of your vehicle. It needs to be visible, legible, and in a contrasting color to ensure that it can be easily read from at least 50 feet away.
Additionally, having a USDOT number is the first step toward obtaining other necessary trucking permits and registrations, such as the MC number. It’s important to keep this number active and updated with accurate company information, as failure to comply with FMCSA guidelines can lead to fines or suspension of your operating authority.
What Is an MC Number?
An MC (Motor Carrier) number, also known as operating authority, is a specific identifier issued by the FMCSA (Federal Motor Carrier Safety Administration) that allows trucking companies to engage in certain types of business operations. Unlike the USDOT number, which tracks safety compliance, the MC number specifically regulates the business aspect of interstate trucking. This number is required for companies that transport regulated commodities for hire or passengers across state lines, as well as those acting as brokers or freight forwarders.
Key Facts About MC Numbers:
- Required for For-Hire Carriers Operating Interstate: Any trucking company that transports goods or passengers for compensation and operates across state lines must have an MC number. This distinguishes for-hire carriers from private carriers that only transport their own goods.
- Applies to Companies Transporting Regulated Goods or Passengers: Companies hauling regulated commodities such as household goods, perishable items, or hazardous materials must obtain an MC number. In addition, if you’re transporting passengers for hire (like in buses or charter services), you will also need this operating authority.
- Needed for Freight Brokers and Freight Forwarder Businesses: If your business involves brokering loads or acting as a freight forwarder (which arranges the transportation of goods but does not transport them directly), an MC number is essential. This allows you to legally conduct brokerage operations across state lines.
Unlike the USDOT number, which is mandatory for safety tracking, the MC number grants authority to operate commercially. Companies must file for the appropriate type of MC authority based on the services they provide—whether it’s for transporting goods, passengers, or acting as a broker. Obtaining the correct MC number ensures that your business can operate legally while adhering to FMCSA regulations.
It’s important to note that some trucking companies may require both a USDOT and MC number, depending on their type of operations. Operating without the correct authority can result in penalties, fines, or loss of business.
Who Needs a USDOT Number?
If your trucking company meets any of the following criteria, you must obtain a USDOT number:
- Operates vehicles with a gross vehicle weight rating (GVWR) over 10,000 lbs.
- Engages in intrastate commerce.
- Transports hazardous materials in quantities that require a safety permit.
Who Needs an MC Number?
Your business will need an MC number if you:
- Are a for-hire carrier transporting goods across state lines.
- Transport passengers or cargo in interstate commerce.
- Transport regulated commodities, such as household goods or medical supplies.
Key Differences Between MC and USDOT Numbers
The main difference between a USDOT and an MC number is their range and purpose:
- USDOT is focused on safety compliance and monitoring.
- MC numbers pertain to the type of business operations, such as transporting goods for hire.
Another key distinction is that all trucking companies must have a USDOT number, but only companies involved in regulated interstate transport need an MC number.
How to Apply for USDOT and MC Numbers
Obtaining a USDOT number is done through the FMCSA’s Unified Registration System (URS). The application process involves submitting details about your trucking company, including business structure, types of vehicles, and types of cargo. Similarly, applying for an MC number involves submitting an application through the FMCSA and paying a registration fee.
Do You Need Both USDOT and MC Numbers?
In many cases, trucking companies will need both identifiers to operate legally. If you are a for-hire carrier transporting goods across state lines, you will require both a USDOT and MC number to remain compliant with federal regulations. Failing to obtain the proper authority could lead to hefty fines or even the suspension of your operations.
