What Are FMCSA and USDOT Numbers and Why You Need One
FMCSA And USDOT Numbers
Several factors need to be considered when looking for a reputable and reliable shipping company. Your research should also determine if the mover has FMCSA and USDOT numbers. This assures you that they are certified to operate by the relevant authorities that govern their industry. These rules also govern interstate movers. Professional movers such as A1 Auto Transport have the FMCSA and USDOT numbers and are willing to provide the information to clients who ask for it.
What are FMCSA and USDOT numbers?
Haulers and commercial vehicles hauling passengers must have a USDOT number and be registered with the FMCSA. You may have done your research while looking for a mover and realized that it is good to hire the services of a credible moving company that has these numbers. So, what exactly are these numbers?
The FMCSA number
The trucking industry in the US is regulated by the Federal Motor Carrier Safety Administration (FMCSA). This agency’s primary mission is to reduce road crashes, fatalities, and injuries involving large trucks and buses.
Depending on the type of authority that the agency grants, the FMCSA number is often identified as "OFF", "MC", or "MX" number. In general, companies that do the following are required to have these numbers:
- Interstate commerce companies that relocate passengers.
- Companies that haul commodities regulated by federal law or those owned by their clients.
The FMCSA dictates the type of cargo a company may carry and the type of operation it may run. Therefore, a company with various business operations may require multiple FMCSA numbers.

The USDOT number
The US Department of Transportation (USDOT) serves Americans by ensuring their transportation system is fast, efficient, convenient, safe, and accessible. Their focus is on meeting the vital national interest and enhancing the quality of life of the American people.
The following companies need this number:
- Those that offer interstate operations and have commercial vehicles that relocate passengers.
- Those that haul cargo and are registered with the FMCSA.
- Commercial intrastate carriers who haul hazardous materials that fall under the category of types and quantities that require a safety permit.
The USDOT is a unique identifier for moving companies. It is useful for collecting and monitoring a company's safety information acquired during inspections, audits, crash investigations, and compliance reviews. Unlike the FMCSA number, which may be issued multiple times, the USDOT number can only be applied once.
As a mover, you need to make a safe and stress-free move. However, this all starts with making the right informed decisions. Do plenty of research when looking for an interstate mover. Among the factors that you should look into are whether the mover has FMCSA and USDOT numbers. This assures you that your property will be shipped by haulers who meet the required standards set by the authorities and that their vehicles have been inspected and deemed safe to operate.
- The USDOT number tracks safety and compliance; the MC number grants legal authority to operate as a for-hire interstate carrier — both may be required.
- FMCSA registration is free via the Unified Registration System, taking 20–40 minutes; MC authority activation can take 2–4 weeks after insurance filing.
- Verify any carrier's USDOT and MC numbers through the FMCSA SAFER system before booking — it shows safety ratings, inspections, and active operating status.
When evaluating a moving or auto transport company, it's crucial to understand the significance of FMCSA and USDOT numbers. These identifiers are not just bureaucratic requirements but vital indicators of a company's legitimacy and compliance with federal safety regulations.
Why Verifying FMCSA and USDOT Numbers Matters
Before entrusting your vehicle or belongings to a transport company, ensure they possess valid FMCSA and USDOT numbers. These numbers indicate that the company is registered with the Federal Motor Carrier Safety Administration (FMCSA) and adheres to safety and operational standards. You can verify these numbers through the FMCSA's SAFER System, which provides access to a company's safety records, compliance history, and other essential information. This due diligence helps protect you from potential scams and ensures that your chosen company operates legally and safely.
Understanding the Difference Between USDOT and MC Numbers
A common point of confusion is the distinction between USDOT and MC numbers. The USDOT number is a unique identifier assigned to companies operating commercial vehicles, primarily used for monitoring safety and compliance. In contrast, an MC (Motor Carrier) number, or operating authority, is required for companies transporting passengers or federally regulated commodities across state lines for compensation. While the USDOT number tracks a company's safety record, the MC number grants the legal authority to operate as a for-hire carrier in interstate commerce. Depending on the nature of the services offered, a company may need one or both numbers.
The Importance of Displaying USDOT Numbers on Vehicles
For companies operating commercial vehicles, displaying the USDOT number on each vehicle is not just a formality; it's a legal requirement. The number must be clearly visible on both sides of the car, in a contrasting color, and legible from a distance of at least 50 feet. This visibility allows for easy identification during inspections and ensures transparency in operations. Failure to display the USDOT number correctly can result in fines and penalties, reflecting poorly on the company's commitment to compliance and safety.
By understanding and verifying these identifiers, you can make informed decisions when selecting a transport company, ensuring that your move or shipment is handled by professionals who prioritize safety and adhere to federal regulations.
Frequently Asked Questions
What is the purpose of a USDOT number?
A USDOT number is the unique identifier the Federal Motor Carrier Safety Administration, or FMCSA, uses to collect and monitor safety information for regulated operations. It connects a company record with inspections, compliance reviews, crash investigations, and other safety data. A USDOT number does not by itself grant interstate for-hire operating authority or prove that a carrier is authorized for every service. When checking a transporter, use the number as the starting point for verifying the company in FMCSA's official records.
Who needs a USDOT number in the U.S.?
Federal rules generally require a USDOT number for motor carriers using commercial vehicles in interstate commerce when the vehicle or combination is 10,001 pounds or more, carries more than 8 passengers for compensation, carries more than 15 passengers without compensation, or meets applicable hazardous-material requirements. States can also require USDOT registration for intrastate carriers. For interstate car shipping, the carrier's exact federal registrations depend on its operation type. Having a USDOT number does not automatically mean the business also needs the same operating authority.
How do I apply for a USDOT number?
New applicants now use Motus, FMCSA's USDOT Registration System, rather than the retired Unified Registration System. You sign in through Login.gov, complete identity verification, establish the appropriate business account, and submit the registration information required for your operation. FMCSA charges no fee for the USDOT number itself, although separate operating authority or other registrations can carry fees. Use legal business details that match your official records because the current system includes identity and business verification before registration actions are completed.
Can I do a USDOT number lookup free online?
Yes. The FMCSA SAFER Company Snapshot provides a free USDOT number lookup and displays company identification, size, cargo information, a safety rating when one exists, inspection and out-of-service summaries, and crash data. For operating authority and insurance, check the appropriate FMCSA registration records rather than treating the snapshot alone as proof of current authority. Before booking car transportation services, match the carrier's legal name and USDOT number with the business that will actually handle your vehicle.
What is the difference between a USDOT number and an MC number?
As of September 28, 2026, a USDOT number identifies the regulated entity, while operating authority defines the interstate for-hire activity FMCSA permits that entity to perform. A carrier may need both, and brokers or freight forwarders hold authority appropriate to their roles. FMCSA has proposed eventually phasing out separate MC numbers and identifying registrations with USDOT-based suffixes, but that change did not take effect with Motus's first release. When reviewing auto transport brokers, verify the specific authority attached to the business rather than checking only for a USDOT number.
Does a pickup truck need a USDOT number?
A pickup truck can need a USDOT number when it is used for business in interstate commerce and meets FMCSA's commercial-vehicle thresholds. The weight test includes 10,001 pounds or more based on the applicable vehicle or combination rating or actual weight, so a pickup towing a trailer can qualify even when the truck alone does not. Passenger or hazardous-material rules can also trigger registration. A pickup used only for personal transportation falls outside these federal motor-carrier requirements, while intrastate business use may still be subject to separate state USDOT rules.
