End of MC Numbers: What It Means for the Trucking Industry in 2025
Big changes are coming to the transportation industry — and if you’re a carrier, broker, or dispatcher, now is the time to prepare. The FMCSA has announced that as of October 1, 2025, it will officially retire MC numbers (Motor Carrier numbers), consolidating all carrier identification under the USDOT number system through the Unified Registration System (URS).
This move is designed to simplify registration, improve oversight, and reduce fraud — but it also means major changes for how carriers operate and stay compliant. Here's everything you need to know about the transition, how it impacts you, and what you can do to stay ahead.
🧩 Why Are MC Numbers Going Away?
For decades, trucking companies, brokers, and freight forwarders have operated using both a USDOT number (for safety and tracking) and an MC number (for operating authority). This two-number system has caused confusion, duplicate filings, and opportunities for regulatory loopholes.
The FMCSA's goal is to:
Streamline registration through a single USDOT-based system
Improve enforcement and accountability by linking all authorities to one unique identifier
Eliminate fraud, including the practice of “rebooting” a carrier with a new MC number to wipe a poor safety record
By retiring MC numbers and moving to the Unified Registration System (URS), the FMCSA will manage all authority types (carrier, broker, freight forwarder) as modular sub-designations under one USDOT number.
🔍 What’s Changing?
Here’s a breakdown of what’s changing with the new system:
No new MC numbers will be issued after October 1, 2025
Existing MC numbers will no longer be used for regulatory purposes
All filings will be made under the USDOT number, with suffixes to define authority types
Paper payments (checks, money orders) will be discontinued
All records — insurance, authority, safety history — will be tied to your USDOT number
FMCSA’s Unified Registration System will be the one-stop portal for all filings
This means carriers will need to update all references to MC numbers in their documents, websites, insurance, load boards, and contracts.
⚠️ What Does This Mean for Drivers and Fleets?
Whether you’re an owner-operator, a fleet manager, or a dispatcher, this shift impacts you. Here’s how:
1. Operational Adjustments
All company materials, from your load confirmations to insurance documents and tractor decals, will need to reflect only your USDOT number. If you don't update this, you risk delays or denied loads.
2. More Transparency (Good and Bad)
The days of “resetting” your authority with a new MC number are gone. Your safety and compliance history will follow your USDOT number, giving good carriers an edge — and holding everyone more accountable.
3. System and Software Changes
Load boards, factoring companies, and TMS providers must also update their platforms to align with the new system. Expect some hiccups during the transition.
4. Broker and Shipper Vetting
Brokers and shippers will now vet carriers using USDOT records alone. If you’re a new carrier, expect new vetting standards based on USDOT age and performance, not MC issuance.
✅ What Should You Do Now?
Preparation is key. Here are five action steps to get ready:
Audit all documents (insurance, contracts, decals, etc.) and remove MC number references
Ensure your USDOT registration is current and accurate
Talk to your insurance provider and factoring company about the transition
Update your load board and TMS profiles
