The FMCSA Contact Center will be closing at 2 p.m. EST on December 24th.

We are currently experiencing a high volume of calls and submissions regarding the Portal and the Drug and Alcohol Clearinghouse. We will do our best to respond in a timely manner. If your issue is concerning an unknown user ID, a locked account or if you are having trouble with your security question answers, please submit your concern, including the email address of the account in question to and a help desk ticket will be opened for you. These types of issues cannot be resolved real time in a phone call or chat. Resolving your issue is very important to us and will be handled as efficiently as possible in the order it is received. For all other Portal/Clearinghouse issues, please have the email address associated with the Portal account in question available when you are connected to a customer service representative and be prepared to provide a detailed description of the issue you are experiencing. For more information, please see our “Portal Account Help” FAQ.

If a sole proprietor owner/operator submits personal information for registration purposes to obtain a USDOT number or operating authority, this information will be publically available on FMCSA websites. This published information may include, but is not limited to, the sole proprietor owner/operator's home address, telephone number and email address when the contact information serves as the business contact information.


Unified Registration System Launched for New Applicants

The FMCSA monitors and ensures compliance with regulations governing both safety (all carriers) and commerce (for-hire carriers). Companies may find they are subject to both registration requirements (USDOT Number and MC Number) or either one separately. To determine if you need to apply for a US DOT number, click here.

FMCSA has launched a phased rollout of the Unified Registration System (URS). All new registration applicants must use the new URS Application.

URS combines various forms that carriers, freight forwarders and brokers currently use to register and update their information with the Agency into a single, online registration application.

Only the initial registration by new applicants will be done using the URS online registration application.

For more general information on URS, click here. 

Internet browsers: Internet Explorer 11 or above, or Google Chrome, Safari or Firefox browsers work best with the URS tool. Internet Explorer 10 can be used in compatibility mode. Failure to use one of these browsers could result in the inability to successfully complete applications for registration.

Already Registered with FMCSA?

Existing registrants (entities that have a US DOT number and/or operating authority) can update their information using all of the existing processes – online and paper forms – until a later date.  On January 17, 2017, FMCSA published a Federal Register notice with more details on the suspension of the URS effectiveness date. Check this site often for updates for existing users.

More options can be found on the left side of the page. You also may find the following useful:

Unified Carrier Registration (UCR) Information

UCR stands for "Unified Carrier Registration," which is not an FMCSA program. It refers to an agreement among the states set up by Congress governing the collection and distribution of registration information and UCR fees paid to states by motor carriers, private motor carriers, brokers, freight forwarders, and leasing companies pursuant to 49 U.S.C. Section 14504a.  The fees collected support state motor carrier safety activities. For more information, click here.
