1. What Does A USDOT Number Mean?

The department of transportation of the US requires you to have a USDOT number. It is an interstate operating authority that you must have if you want to carry on with your interstate commerce and transport operations. It is also a unique identifier that is assigned to any moving and logistics company involved in intrastate and/or interstate moves. The federal motor carrier safety administration and the government will use this number to keep a track of your safety records including compliance, registration status, ratings, investigations, inspections, and much more. If you want to access this information, it is available on the FMCSA website.

2. What Is Required To Get A USDOT Number?

First, you will have to create a business entity and start operating your commercial transportation company. It can be an LLC or a corporation.

Declaring your operation classification is also important because it gives the government a clearer picture of how you conduct your business and in what capacity. You could be conducting your business for:

  • Private passenger/non-business passengers
  • US mail
  • Migrant

If you are moving or are in the business of moving hazardous materials, you will have to declare it in the form. You must also indicate whether you are moving this material as a shipper, carrier, bulk shipper, or non-bulk shipper.

Remember that your USDOT number application is free and it is often combined with an MC number application. If you are asked to pay a fee for this application, it means that you have filed for both your USDOT number and MC number at the same time.

The fee that you pay for your MC number is non-refundable so you should make sure that the application is always filed correctly.

4. How Do I Get A USDOT Number?

To get a USDOT number, you will have to determine whether you need it in the first place or not. Most carriers do but a few of them will be exempt from it. Answer the following list of questions to understand whether you need a USDOT number or not:

If you have answered yes to any of the questions above, you need to apply for a USDOT number right away. If none of these apply to your business, you may only have to register with your state office or local jurisdiction. You do not have to file for a USDOT application.

To apply for a USDOT number, you must have the necessary information. The entire application process is very simple and straightforward. You are going to need a few details apart from your name and address of your company and the like. This includes:

MCS-150 C

You will fill out this form when you need a USDOT number and need to fill out an intermodal equipment provider application as well

You must fill out the necessary information in the appropriate form and mail it to the FMCSA.

5. Can I Have Two USDOT Numbers?

No. You cannot have two USDOT numbers because they are unique identification numbers that are given to companies. They are not transferable to anybody. They are operating authorities that are given to you and because they are unique identifiers, they help the government track your safety history. As a carrier, you will be assigned a single USDOT number for all your trucks in your fleet. However, if you wish to register two different vehicles separately, you will be assigned two USDOT numbers.

6. Do I Need A Different DOT Number For Each Truck?

No. You do not need a different DOT number for each one of your vehicles. You just need one USDOT number for your company which will be assigned to your enterprise. You will have to contact your local state department of transportation office or the FMCSA to apply for a USDOT number. There will be additional requirements such as medical exams of your drivers that you will have to fulfill apart from the general information of your company. A USDOT number is only assigned to registered commercial vehicles. This means that if you have more than one commercial vehicle, you can apply for more than one USDOT number by going through a registration process for each commercial vehicle separately.

7. Can I Add A Truck To My DOT Number?

Yes. You can add a track to your DOT number because the vehicle will be under your company’s name. Because the USDOT number is assigned to your enterprise and not to your individual vehicles, you do not have to acquire a separate DOT number for the vehicle. However, if you choose to register the commercial vehicle separately, you will have to go through the entire registration process again. This means that you may have another USDOT number for your new truck if you choose to do so.

8. Does A Private Carrier Need A DOT Number?

If you own a private motor carrier company and are involved actively in transporting your own cargo, you will need to have a USDOT number. If you own a business that uses, sells, or buys cargo that is being hauled across interstate lines, you will need a USDOT number. As a private motor carrier, you can transport your goods within the state or across state lines. For this, you will need a USDOT number but you don’t need an operating authority which is the MC number.

9. Who Is Exempt From DOT Number?

There are certain carriers that are exempt from the DOT number. They must fulfill the following conditions:

  • If their vehicle is not used to transport any types of materials requiring any safety permit in intrastate commerce
  • If the gross weight of the vehicle is less than 10,000 pounds, they are not required to obtain a USDOT number
  • If the vehicle is designed to transport not more than 8 passengers including the river, it does not have to obtain a USDOT number

10.  Can I Use My Old Number?

USDOT numbers are non-transferable and they are your unique identifiers. This means that only one USDOT number is assigned to a company during its lifetime. This is going to stay with your enterprise forever and the government is going to use this record to keep a track of your information, safety, and various compliances. Each person is required to have a separate registration for their commercial vehicle. For any corporation, business organization, partnership firm, and similar enterprise, the USDOT number is going to remain the same even if there is a change in their information including the company name, address, or other information. Even if your company is going through an organizational restructuring procedure, this unique identifier is going to remain the same.

You will have to file an MCS 150 motor carrier identification report within 30 days of any change that you may have made to keep your records updated with the government.

11.  What Vehicles Require A DOT Number?

All the vehicles involved in intrastate and interstate commerce require a USDOT number provided they fulfill the following criteria:

  • If your vehicle is used to transport various types of hazardous materials and you require a safety permit to facilitate the same
  • If your vehicle has a total weight of 10,000 pounds or more
  • If your motor vehicle has been designed to transport at least 8 passengers and more including the driver, for a compensation
  • If your motor vehicle has been designed to transport more than 15 passengers including the driver, in exchange for compensation
  • If you are involved in interstate commerce where your vehicle travels within a state and a place outside of the state, whether it is inside the United States or outside its boundary
  • If your vehicle travels between two places in a given state, through another state, or any other place that is located outside of the United States

12.  Can Two Companies Use The Same DOT Number?

No. USDOT numbers are non-transferable and each is assigned to a single company. They are unique identifiers and cannot be shared by two or more companies.
