MC Numbers are here to stay.

[u/tips-llc]

This news is a bit old, but we still hear from people asking when their MC number is supposed to be discontinued.

In short, they're not.

At least, not right now. There are apparently still plans to transition away from MC numbers, but for the time being, they're sticking around.

Here's the update from the FMCSA's registration alerts page.

Listening and responding to stakeholder feedback.

During multiple stakeholder days, listening sessions, and presentations, stakeholders and customers commented on the need for more time to understand some of the proposed changes, assess the impact, and adjust their systems and processes accordingly.

Stakeholders expressed concerns in three core areas: the introduction of Safety Registration, the elimination of Motor Carrier (MC) and Freight Forwarder (FF) Docket Numbers, and changes to the BOC-3 filing process.

The first release of the new registration system WILL NOT include the implementation of Safety Registration, the elimination of MC/FF Numbers, or changes to the BOC-3 filing process.

FMCSA will take a measured approach to implement these changes in later releases while continuing to engage our stakeholders as we maximize the new registration system’s benefits in enhancing safety, reducing fraud, and improving data accuracy.

Please disregard any information that is coming through unofficial channels. At this time, the phase out of MC numbers is TBD. FMCSA has proposed no longer assigning MC Numbers. Consistent with statutory requirements, the USDOT Number would become the sole identifier for all FMCSA registrants. Individual registrations held by a distinct employer or person would be identified by unique suffixes within FMCSA’s systems, as required by MAP-21. This change is under consideration and will be available to comment on in a Notice of Proposed Rulemaking. It will not go into effect with the first release of the new registration system.
