In general, companies that do the following are required to have interstate operating authority (MC number) in addition to a DOT number:

• Operating as for-hire carriers (for a fee or other compensation)
• Transporting passengers, or arranging for their transport, in interstate commerce
• Transporting federally regulated commodities or arranging for their transport, in interstate commerce

As of December 12, 2015, all entities applying through the Unified Registration System will obtain a USDOT number.

Operating Authority means the registration required by 49 U.S.C. 13902, 49 CFR part 365, 49 CFR part 368, and 49 CFR 392.9a.

FMCSA operating authority is also referred to as an "MC," "FF," or "MX" number, depending on the type of authority that is granted. Unlike the USDOT Number application process, a company may need to obtain multiple operating authorities to support its planned business operations. Operating Authority dictates the type of operation a company may run and the cargo it may carry. Mexico-domiciled carriers may click here for information on registering with FMCSA.

New Applicants must register online via the Unified Registration System. They will be issued a USDOT number and an MC/MX/FF number. Existing entities that already have a USDOT number and/or MC/MX/FF number must apply via the OP-1 series forms, or online (click here), providing their existing USDOT number (and MC/MX/FF numbers, if they are applying for an additional authority.)

All of this also dictates the level of insurance/financial responsibilities a company must maintain. Carriers not required to have operating authority include:

• Private carriers (carriers that transport their own cargo)
• "For-hire" carriers that exclusively haul exempt commodities (cargo that is not federally regulated
• Carriers that operate exclusively within a federally designated "commercial zone" that is exempt from interstate authority rules. A commercial zone is, for example, a geographic territory that includes multiple states bordering on a major metropolitan city, such as Virginia/Maryland/Washington, DC

More information on motor carrier insurance requirements can be found on our web site.

Biennial Update

Federal Motor Carrier Safety Administration (FMCSA) requires all entities under its jurisdiction to update their information every two years. You are required to provide this update every two years even if your company has not changed its information, has ceased interstate operations since the last update, or is no longer in business and you did not notify FMCSA.

Failure to complete a Biennial Update will result in deactivation of your USDOT number and may result in civil penalties of up to $1,000 per day, not to exceed $10,000.

Updating your information is free. We have included instructions below to help you complete your biennial update.

• Deadlines for Filing an Update
• Update via the FMCSA Ask Website
• Update via US Mail (may delay the process)

What is the Deadline to Update?

Filing schedule: Each motor carrier or intermodal equipment provider must file the appropriate form at the following times:

• Before it begins operations; and
• Every 24 months according to the following schedule:

If the next-to-last digit of its USDOT Number is odd, the motor carrier or intermodal equipment provider shall file its update in every odd-numbered calendar year. If the next-to-last digit of the USDOT Number is even, the motor carrier or intermodal equipment provider shall file its update in every even-numbered calendar year.

In general, a USDOT Number is required if you are operating in interstate commerce and meet the following criteria:

• You have vehicles that are over 10,000 lbs. (GVWR, GCWR, GVW or GCW)
• You transport between 9 and 15 passengers (including the driver) for compensation, whether direct or indirect
• You transport 16 or more passengers
• You haul hazardous materials

Click here for a step-by-step tool that helps you determine whether you need a USDOT or MC number. There is no charge to get a USDOT number. For more information on how to get a USDOT number, please see the FAQ "How do I get a US DOT number?" For some definitions of FMCSA terms, click here.

If you would like information on getting operating authority as a for-hire carrier (MC/MX/FF numbers), click here.

If you are an existing company changing your form of business, click here. 

If you already have a USDOT number, you must complete the appropriate motor carrier operating authority forms (OP-1 series) and submit them to FMCSA for processing. Please read the instructions for the appropriate OP-series form carefully to avoid errors.

If you do not already have a US DOT number or other authority, you must begin the online registration process via our Unified Registration System. This process requires a credit card.

There is a $300 fee for each operating authority requested.

PLEASE MAKE SURE YOU READ THE INSTRUCTIONS AND APPLY FOR THE CORRECT TYPE OF MOTOR CARRIER OPERATING AUTHORITY. THE $300 FILING FEE IS NON-REFUNDABLE.

The FMCSA's policy is to assign a unique USDOT identification number to each person required to identify themself with FMCSA under 49 U.S.C. 13902, 31134 and 49 C.F.R. 390.19T or 390.200T.  USDOT numbers are not transferable and are assigned to only one person and remain assigned to that person forever.  A person includes an individual, corporation, partnership, or other business organization as authorized by state law.  Each separate and distinct person must have separate registration.

For corporations, partnerships and other business organizations, the USDOT number will remain the same when there is a change in company officials, address or other demographic information, and the corporation, partnership, or other business organization will continue operations as the same legal person/entity. In case of a change in demographic information, the motor carrier is required to file an updated Form MCS-150, Motor Carrier Identification Report, within 30 days of the change. 

We will allow a sole proprietor to maintain its USDOT number when it changes its current form of business, and the new entity will continue to operate virtually the same (absent the form of business change) as before the change.  There would be no change in company officials, address, or other demographic information and the new entity will maintain identical operations, employees and assets.  We will permit a change in the Tax ID number based on the new articles of incorporation.

It is important to note that the regulation has not changed.  The Office of Registration and Safety Information is often asked whether a new USDOT number is or is not required following motor carrier ownership, form of business, or operational changes.  The office recently provided clarification and direction for what must be done when these situations arise.

The compliance date for this requirement (49 CFR 390.19) occurred November 1, 2013.

Filing schedule: Each motor carrier or intermodal equipment provider must file the appropriate form at the following times:

• Before it begins operations
• Whenever there is a change in information (address, telephone number, email, # power units, etc.)
• Every 24 months, according to the following schedule:

If the next-to-last digit of its USDOT Number is odd, the motor carrier or intermodal equipment provider shall file its update in every odd-numbered calendar year. If the next-to-last digit of the USDOT Number is even, the motor carrier or intermodal equipment provider shall file its update in every even-numbered calendar year.

FMCSA also requires you to update your registration information within 30 days of any change.  FMCSA considers updates completed by a motor carrier, Intermodal Equipment Provider (IEP), or Hazardous Materials Safety Permit (HMSP) holder if changes are reported within 12 months prior to the biennial update due date.  In which case the entity will not receive a Biennial Update Reminder until the next biennial update due date. 

To find out the current status of your USDOT number, click here to search by name or number at the SAFER Company Snapshot. 

The cost for each individual Operating Authority is a one-time fee of $300. Separate filing fees must be submitted with the application at the time of processing for each Authority sought. For instance, requests for Passenger Authority and Household Goods Authority will require two $300 fees ($600). Payments can be combined. If both authorities are the same type (like common and contract carrier authorities for property), there is only one fee. FILING FEES ARE NON-REFUNDABLE.

There is a $14 charge for processing of a name change and an $80 fee for requesting reinstatement of an authority if it is revoked. For more information on operating authority fees, click here.

If you perform trade, traffic, or transportation exclusively in your business’s domicile state, this is considered intrastate commerce.

If your trade, traffic, or transportation is one of the following, this is considered interstate commerce. Source: 49 CFR 390.5.:

• Between a place in a state and a place outside of such state (including a place outside of the United States)
