What is a DOT Number? A Simple Guide for Fleet Owners

Planning to run a fleet of commercial vehicles in the U.S.? Whether your focus is on transporting goods or passengers, a DOT number is a crucial requirement for your operations. 

Obtaining a DOT number is not a one-size-fits-all process; the criteria depends on your specific business and the type of transportation you plan to undertake. 

If you find yourself puzzled by the intricacies of DOT numbers, worry not – our blog is here to demystify it all. Discover the necessity and benefits, and gain clarity without any unnecessary delay. Let’s dive in and simplify the DOT number experience!

What is a DOT Number?

A DOT number, or Department of Transportation number, is a 12-digit alphanumeric code issued by the Federal Motor Carrier Safety Administration(FMCSA) to registered commercial vehicles.

Established in 1963, its primary purpose is to uniquely identify commercial vehicles. This number is crucial, especially for carrier vehicles exceeding specific weight limits, transporting a number of paying passengers or operating across state lines.

What is a DOT Certfication?

A DOT number is for transport companies; a DOT certification is a badge for drivers, showing they’re
qualified to drive commercial vehicles in the United States.

Almost every state insists that drivers working for trucking companies should have this certification,
whether they’re driving big trucks or smaller delivery vehicles. If a driver has a commercial driver’s
license, it means they’re DOT certified.

To get DOT certified, drivers go through a process, that includes:

Completing an application
provided by FMCSA.

Passing the DOT
physical examination.

Passing the
driving tests.

The U.S. Department of Transportation ensures this whole process is executed accurately. Since this
certification needs drivers to be in good physical shape, they must undergo this process every two years to ensure the continuity of their certification.

What is a DOT Number Used For?

Obtaining a USDOT number significantly enhances safety on U.S. interstate routes for both individuals and transported goods. You must get a USDOT number if you have a vehicle that falls into
any of these categories:

  • It’s used to carry hazardous materials that need a safety permit within a single state.
  • The vehicle should either weigh 10,001 pounds or more, be designed to transport more than 8 paying passengers (including the driver), or be designed to carry more than 15 passengers, including the driver, even if there’s no charge for the ride.

And if your vehicle is part of interstate commerce, that means it’s connected to business or
transportation activities within the United States in the following ways:

Between a place in one state and a place outside of that state, including places outside of the United States

Between two places in one state, the route takes it through another state or a place outside the United States.

Between two places in one state, but it’s part of trade or transportation that starts or ends outside of that state or the United States.

The FMCSA requires you to get a USDOT number and follow the federal rules if your vehicle meets these criteria.

Apart from the federal regulations, some states need companies operating only within their state to get a USDOT Number. These states include:

Now that you understand the basics, let’s delve further and explore the benefits of having a USDOT number.

What are the Benefits of Having a USDot Number?

Think of a DOT Number as a unique ID that helps monitor and regulate large trucks and their drivers in the U.S. In addition to its primary purpose, it comes with several other advantages, such as:

Essential in Maintaining the Safety of the Roads

The DOT number is essential for overseeing a company’s safety track record, including crash investigations, compliance checks, and drug and alcohol testing. While complying with DOT regulations might initially seem restrictive, it is vital for ensuring road safety.

Your DOT number also serves as a gateway to your safety and performance data through the FMCSA’s Safety Measurement System (SMS). This system offers insights into roadside inspections, crash records, and Inspection Selection System status, enabling you to gauge the likelihood of a safety investigation

Legitimates Your Business

By having a USDOT number, your customers, other companies, and drivers recognize you are trustworthy and prioritize safety.

Just as you would check on the legitimacy of a company you’re paying to complete a service, your customers want to know they can depend on you to get their freight where it needs to go in a safe and timely manner. Your DOT number gives them that peace of mind.

Useful in Commercial Transportation

A DOT number is usually a must if you want to be part of commercial transportation. You might need it to get deals with shippers, freight brokers, and other partners in the supply chain.

Useful for Cross-Border Operations

If a carrier intends to operate between U.S. states and countries like Canada or Mexico, having a DOT number is often necessary due to international agreements and U.S. regulations.

Identification of the Vehicle

A DOT number can help in identifying commercial motor vehicles, which can be crucial for safety inspections and enforcement activities. It aids in tracking the vehicles and their owners, even if they operate across state lines.

Increased Credibility and Trust

When an auto transport company has a DOT number, it signals that the company is abiding by state regulations. It provides evidence that both the company and its drivers are dedicated to lawful and secure operations, adhering to government-set guidelines

After getting a comprehensive understanding of DOT Numbers, let’s shift our focus toward understanding what an MC number is and how it differs from a DOT Number.

What is MC Number?

The MC number, short for Motor Carrier number, is like a special code that identifies companies in the
commercial freight industry given to companies by the FMCSA. A logistics company must be allowed to
move goods between different states to get an MC number.

The reason for having an MC number is that companies can legally transport goods across state borders.
You don’t usually need to display this number on your vehicles, but it’s necessary when you’re crossing
into another state.

The MC number is a special identifier that allows moving companies to haul cargo across state lines.

So, what’s the difference between a DOT Number and an MC Number? Let’s unveil.

Difference between DOT Number and MC Number

Look at the Number
DOT numbers are displayed on the vehicle’s cab and are preceded by the letters USDOT.
MC numbers also found on the cab, are usually shorter and include the state abbreviation where the company stands before the number.
Number of
Classifications
Every company, big or small, has only one DOT number that the government uses to keep all its information in one place
With MC numbers, a company can have different classifications under one number, especially if they transport various goods across borders.
Who Must Have
Moving companies operating commercial vehicles across state lines must have a USDOT Number.
An MC (Motor Carrier) number is required for moving companies that transport goods or passengers across state lines as part of their business operations.
How can you get it?
You can apply for the US DOT Number by going to the FMCSA’s website.
To obtain an MC number, you must first get a USDOT number. Once you have the DOT Number, you can visit the FMCSA website, sign up your company, complete the form, and pay the required fee.
Remember: A key distinction between a DOT Number and an MC Number is you might require a USDOT number even if you’re working only within a single state, while an MC number is necessary only when you plan to travel across state borders

Final Notes

Starting any business is tough, especially when it’s in the trucking or car shipping industry. You are already juggling with a new set of rules and responsibilities.

But, before you go too far, ensure whether you need a DOT Number. If yes, it’s wise to determine if an MC number is also necessary. Once your company secures both of these, you’ll be on the right path to establishing a thriving transportation business
