FMCSA issued MC #999999 in January 2017.  Due to a system limitation, FMCSA started recycling unused and unissued MC numbers.  In June 2018, FMCSA will start issuing docket numbers which can eventually grow to 8 digits, starting with MC #1000000.  FMCSA is asking that State and industry partners start preparing their downstream systems and data processors to accept MC numbers up to 8 digits in length.  There will be no change to 6-digit MC numbers that have previously been issued.  The Registration and Safety Information Office is working with Outreach, FMCSA Field Offices, Trade Organizations, and State and Industry Partners to aggressively market this upcoming change. 

As of April 13, 2018, reinstatements, name changes and address changes for operating authorities must be submitted using the MCSA-5889 form (click here).

As of February 4, 2018, FMCSA is no longer accepting expired paper versions of the MCS-150, MCS-150B and MCS-150C forms. Please click here if you would like to access the updated forms with an expiration date of 4/30/2019. Note, FMCSA will accept system-generated forms prepared by MCMIS.

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.

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.
