Let Us Help You With...

>> Active or Inactive USDOT Number

If your USDOT Number is ACTIVE and you need to make updates, you can do so online on our L&I Public Site.

If your USDOT Number is INACTIVE, you won't have online access to make updates. Depending on the entity type, please complete:

  • An updated Motor Carrier Identification Report (Form MCS-150), or 
  • Combined Motor Carrier Identification Report and Hazardous Materials Permit Application (Form MCS-150B), or 
  • Intermodal Equipment Provider Identification report (Form MCS-150C)

Submit either document by fax, or electronically by using our FMCSA Contact Center Form, for quickest processing. For general inquiries, you can check any USDOT number status on the SAFER Company Snapshot web page. Visit our FAQs on our FMCSA Contact Center Form for additional information. 

>> Unified Registration System (URS) for New Registrants

URS combines all Registration forms into a single, online registration application. Only new registrants must use URS. For more general information on URS, click here. 

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.

Internet browsers: The URS tool must be used with Internet Explorer 11 or above, or Google Chrome, Safari or Firefox browsers. Internet Explorer 10 can only be used in compatibility mode

Get Started

>> Existing Registrants

Current entities that already have a USDOT number and/or operating authority can update their information using all of the existing processes – online and paper forms. On January 17, 2017, FMCSA published a Federal Register notice detailing the suspension of URS deployment until further directions are given. Please check this page for updates on that subject.

>> Unified Carrier Registration (UCR)

UCR 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.
