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.

If you would like to suspend operations, you can request voluntary revocation of operating authority (OA) registration by following the steps below:

Step 1: Verify your current Operating Authority registration status.

Step 2: Fill out Form OCE-46

Complete Form OCE-46 to request Voluntary Revocation of your authority (MC/MX/FF). 

The form must be notarized or signed in the presence of a FMCSA staff member.

Step 3: Fill out Form MCS-150 or MCS-150B to: (A) Inactivate or (B) Update USDOT registration

 A) To inactivate your USDOT number, follow these steps:

1. Complete either an updated MCS-150 or MCS-150B form (for Hazmat Carriers).

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. 

To check a company's safety rating, you can visit the FMCSA's Safety and Fitness Electronic Records (SAFER) website. On the SAFER website, you can search for a company by name, USDOT number, or MC/MX number. Once you have found the company you are looking for, you can access their safety rating and other important information, such as their inspection and crash history. If you have any questions or need further assistance, you can contact the FMCSA's Safety Compliance and Safety Accountability (CSA) program.

You can now update the following USDOT company information online via FMCSA Portal: 

• Applying for additional operating authority 
• File a biennial update (MCS-150) 
• Change of address 
• Reinstate Operating Authority 
• Reapplication for USDOT Number after revocation 
• Update cargo tank

Other transactions, like legal name change requests, that required paper forms before the transition of the Registration options (L&I page) to the FMCSA Portal will continue to be submitted on paper. See the FMCSA Registration Forms page for details.

To proceed with updating your company information, check current status online in SAFER Company Snapshot. Then, proceed to request updates online via FMCSA Portal or on paper via the FMCSA Registration Forms. If the latter, please expect a minimum timeframe of 8 business days for review and processing. 

If you don't have an FMCSA Portal, follow the steps below:

Step 1 -- Obtain Your USDOT PIN: Make sure you have your company info handy (i.e., EIN, USDOT) and go to SAFER and select the option to request a PIN and follow the prompts. The PIN will be sent to the e-mail or cell phone currently on file. 

Step 2 -- Obtain Your Login.gov E-mail: Login.gov is the official, single sign-on service for US Government services online. If you don't already have a Login.gov e-mail, sign-up for free at https://login.gov/create-an-account/ 

Step 3 -- Create the FMCSA Portal Account: Visit the FMCSA Portal website at FMCSA Portal and walkthrough the account instructions. You'll only need to go through the steps and use your FMCSA PIN once during account set-up; after that, the Login.gov e-mail address is all you'll need to access your company record.

For the purpose of complying with the new requirements for medical certification, it is important to know how you are using the CMV. To help you decide, follow these steps:

Step 1: Do you, or will you, use a commercial driver’s license (CDL) to operate a CMV in interstate or intrastate commerce?

• Interstate commerce is when you drive a CMV:
  • From one State to another State or a foreign country
  • Between two places within a State, but during part of the trip, the CMV crosses into another State or foreign country
  • Between two places within a State, but the cargo or passengers are part of a trip that began or will end in another State or foreign country
• Intrastate commerce is when you drive a CMV within a State and you do not meet any of the descriptions above for interstate commerce
• If you operate in both intrastate commerce and interstate commerce, you must choose interstate commerce

Step 2: Once you decide whether you operate (or will operate) in interstate commerce or intrastate commerce, you then must decide whether you operate (or expect to operate) in a non-excepted or excepted status.

Interstate Commerce:

• You operate in excepted interstate commerce when you drive a CMV in interstate commerce only for the following excepted activities:
  • To transport school children and/or school staff between home and school
  • As Federal, State or local government employees
  • To transport human corpses or sick or injured persons
  • Fire truck or rescue vehicle drivers during emergencies and other related activities
  • Primarily in the transportation of propane winter heating fuel when responding to an emergency condition requiring immediate response such as damage to a propane gas system after a storm or flooding
  • In response to a pipeline emergency condition requiring immediate response such as a pipeline leak or rupture
  • In custom harvesting on a farm or to transport farm machinery and supplies used in the custom harvesting operation to and from a farm or to transport custom harvested crops to storage or market
  • Beekeeper in the seasonal transportation of bees
  • Controlled and operated by a farmer, but is not a combination vehicle (power unit and towed unit), and is used to transport agricultural products, farm machinery or farm supplies (no placard-able hazardous materials) to and from a farm and within 150 air-miles of the farm
  • As a private motor carrier of passengers for non-business purposes
  • To transport migrant workers
• If you answered yes to one or more of the above activities as the only operation in which you drive, you operate in excepted interstate commerce and do not need a Federal medical examiner’s certificate
• If you drive for more than just the above activities, you operate in non-excepted interstate commerce and are required to provide a current medical examiner’s certificate (49 CFR 391.45), commonly referred to as a medical certificate or DOT card, to your SDLA. Most CDL holders who drive CMVs in interstate commerce are non-excepted interstate commerce drivers
• If you operate in both excepted interstate commerce and non-excepted interstate commerce, you must choose non-excepted interstate commerce to be qualified to operate in both types of interstate commerce

Intrastate Commerce:

• You operate in excepted intrastate commerce when you drive a CMV only in intrastate commerce activities which your State of licensure has determined do not require you to meet the State’s medical certification requirements
• You operate in non-excepted intrastate commerce when you drive a CMV only in intrastate commerce and are required to meet your State of licensure’s medical certification requirements
• If you operate in both excepted intrastate commerce and non-excepted intrastate commerce, you must choose non-excepted intrastate commerce

Step 3: Provide your State Driver Licensing Agency with your self-certification of your operating status. If you self-certify to non-excepted interstate, you must provide your SDLA with either the original or copy of your current medical examiner’s certificate as required by your SDLA.

If your medical examiner’s certificate is only valid with a variance granted by FMCSA, you may also be asked by your SDLA to provide a copy of that variance document.

To register for a USDOT number, you can apply online through the FMCSA's Unified Registration System (URS). The URS system will guide you through the registration process and help you determine what other registrations, permits, or authorities you may need. Before you register for a USDOT number, it is recommended that you review the FMCSA's guidance on registration requirements and ensure that you have all the necessary information and documentation. Once you have completed the registration process, you will receive a USDOT number that must be displayed on your vehicles and used in all your company's transportation-related activities.

For more information about registering with the FMCSA, go to the FMCSA Registration page. 

To find the status of an existing company/USDOT#, click here for the SAFER Company Snapshot page.

If your USDOT Number is active, online updates can be made via your FMCSA Portal account. Don't have an FMCSA Portal Account to Make Online Changes? 

If your number is inactive, you will need to submit a paper form. See our Registration Forms page for more information.

Check SAFER to verify your current USDOT Number status.

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.

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 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.

You can file for the following operating authorities with the OP-1 Application For Motor Property Carrier and Broker Authority (definitions can be found in 49 CFR 390.5):

• Motor Common Carrier of Property except Household Goods
• Motor Contract Carrier of Property except Household Goods
• Motor Common Carrier of Household Goods
