The Underground Market for MC Numbers: What Carriers, Brokers, and Shippers Need to Know

FreightWaves and The Bannon Report recently covered something that doesn't get enough direct attention in this industry: an active underground market for MC numbers. The FMCSA issued a bulletin in response. Below is a summary of what the reporting covers, along with my own read on what it means in practice.

What the FMCSA Actually Warned

The agency's position is straightforward: operating authorities are not commodities. MC numbers and USDOT authorities cannot be transferred unless they move as part of a legitimate corporate transaction — a merger, acquisition, or documented ownership change. Buying, selling, leasing, or renting an authority outside those circumstances can trigger enforcement action, including inactivation of the USDOT number, revocation of operating authority, and cancellation of registrations — all of which immediately cut off a carrier's ability to move interstate freight.

An operating authority is the regulatory identity of a specific motor carrier. Insurance filings, safety records, and compliance history all attach to it. When that identity quietly changes hands, the public record stops reflecting who is actually running the operation.

How the Underground Market Works

Investigators documented authorities being advertised online, transferred through informal brokers, and sold as full "carrier packages" — including company email accounts and dispatch contacts. In one case cited by The Bannon Report, an individual stated they would sell their operating authority to the first buyer willing to show up with $20,000 cash.

We saw this happening quite a bit a few years back, and the cases were actually pretty easy to read. When someone is offering that kind of money for an authority, they are not looking to skip a few months of new-entrant scrutiny — the price point signals a different purpose entirely. A new carrier who just wants to shortcut the process can't reasonably justify spending more than $3,000–$5,000 for something that saves them four to six months of building a business. The higher-dollar buyers are a different problem.

Why Old Authorities Are Attractive

The demand side isn't hard to understand. New entrants face real headwinds: brokers apply extra scrutiny during the new-entrant period, insurance costs are higher without an operating history, and an older authority already has a profile in brokerage systems that passes a surface-level check. For some operators, a used MC number looks like a path around all of that.

The honest answer is that the way through the new-entrant period has changed. Running broker freight exclusively is far less viable than it used to be, and the carriers who approach it like the old playbook are the ones who struggle longest. You need at least some direct freight relationships from the start. That shift in thinking also changes the math on buying a shortcut — if your model depends on direct relationships anyway, the value of skipping ahead in a broker's system drops considerably.

For new carriers grinding through that period: there is freight out there, and there are brokers and shippers who will work with you. Go after each one as if they are the only account you will ever run for — you have to be one of the best options they have. Build on each relationship over time, and start working toward direct freight as early as you can. You cannot build a real business on brokered freight alone.

The Fraud Connection

This is where the issue goes beyond a regulatory question. A purchased authority already has insurance filings and a history in brokerage systems. That borrowed credibility is enough to book a load. Investigators tied unauthorized authority transfers directly to several fraud patterns: double brokering networks re-tendering freight under an identity that passes an initial check; chameleon carriers with poor safety records cycling through recycled identities to stay active on load boards; cargo theft operations using purchased or stolen authorities to pick up loads they never intend to deliver; and identity impersonation schemes where bad actors operate under a legitimate carrier's authority without their knowledge.

Fraud actors only need a short window — a believable identity, a working email, a phone number, load board access, and one broker willing to tender freight. By the time the authority is revoked, the load is already gone.

What Brokers and Shippers Should Watch For

The article points to the standard warning signs: sudden changes in contact information, mismatched addresses, recently reactivated authorities, differences between insurance filings and what the carrier is providing during a tender. These are worth monitoring — but their limit is that sophisticated fraud actors already know they need to control the email, phone number, and address before they move. They pay for that access up front.

The deeper fix is getting back to a relationship-driven business model. When you actually know the carriers you work with and have a real operating history together, you don't need a checklist to know something is off. The market has moved toward transactional, and that shift has not been good for anyone. When capacity tightens again, the brokers and shippers who built real carrier relationships will be in a much stronger position than those who treated every load as a spot transaction.

Does the Bulletin Actually Change Anything?

There are more than 1.8 million entities registered with the USDOT. The FMCSA cannot audit quiet handshake transfers at scale — enforcement typically only happens when there's a major accident, a formal complaint with solid evidence, or an active investigation already underway.

The wording in the bulletin isn't new. This has been going on, and the agency knows it. I read it more as a shot across the bow — something to make people think twice before selling their LLC or corporation. But when you're talking about the amounts being offered to chameleon carriers looking to commit fraud, a bulletin is not going to stop a struggling carrier from taking $20,000 for their authority when their business is failing. The financial pressure wins that conversation.

The bulletin is a useful reminder that these transactions carry real legal risk. The industry-level fix requires better verification standards, tighter onboarding, and more relationship-driven practices across the board.
