When buying or selling an MC Number:
- Understand the legal framework: The FMCSA strictly prohibits the standalone buying, selling, or trading of USDOT numbers and Operating Authorities (MC numbers). Unauthorized transfers can result in the deactivation of the number and the stripping of registrations to prevent Chameleon Carrier fraud.
- Structure as a business acquisition: To legally acquire an MC number, the transaction must be structured as a formal business sale. In a stock sale, the buyer acquires the entire legal entity, allowing the authority to remain attached; in an asset sale, the authority does not transfer automatically, and both parties must formally notify the FMCSA to document the change.
- Use compliant tax structures: Professional M&A advisors often use F-reorganizations for these deals. This legal structure treats the transaction as a stock sale to preserve regulatory continuity (the MC number) while allowing the buyer to benefit from asset-based tax treatment.
- Perform rigorous due diligence: Legitimate deals typically take 8–10 months and require a deep dive into hidden liabilities. Buyers must look beyond the FMCSA register to audit active litigation, open insurance claims, and driver qualification files, as these liabilities transfer to the new owner upon closing.
Trucking company for sale, age: 2 years, FMCSA safety score: good standing. This MC is ready to work for you from Day 1. Whether you want to run it yourself, lease it out, or activate Amazon Relay—the foundation is already built.
That was the anonymous post in a public Facebook group. Similar posts populate private and public Facebook industry groups to help buy and sell USDOT Number or MC Number, typically listing the same data points: age of the MC, fleet size, number of inspections, safety scores or rating, and whether an Amazon Relay account is attached.
The Federal Motor Carrier Safety Administration issued a bulletin March 13 that USDOT Numbers and Operating Authorities cannot be bought, sold, or traded. As part of a broader crackdown on chameleon carriers, the agency said it will deactivate numbers and strip registrations from carriers found in unauthorized transfers.

What does fraud look like at the transaction level?
“Organized actors have learned that acquiring a carrier with an established safety record and existing broker relationships is a more efficient entry point than building a new identity from scratch,” said Eric Heath, managing director of Bluejay Advisors. “And the economics of that scheme are compelling enough that it has driven a meaningful increase in suspicious ownership changes connected to cargo theft activity.”
Aged MC acquisitions have become a standard operational tactic and indicator for freight fraud, Heath said, as an established authority bypasses the broker and shipper vetting that new entrants face.
The return on a well-aged number can exceed the acquisition cost, said Heath, adding, “The most sophisticated schemes do not look like fraud at first. They look like a carrier with a credible history, clean insurance, and an active presence on load boards. The deception only becomes visible after the freight is gone.”
Heath listed red flags that indicate a suspicious MC acquisition:
- Buyer does not ask regarding the seller’s business but is looking to move quickly at premium valuations with minimal due diligence and pricing that exceeds the MC’s value.
- Buyer with minimal or no real operating business the MC (thin footprint and unclear operations).
- Disproportionate focus on the MC number’s age, history, and broker relationships, not the business.
- Multiple prior ownership transfers in the authority’s recent history that does not support a legitimate operating plan.
- Requests to retain or transfer the seller’s identity-linked assets (emails, phones, dispatch relationships and broker contacts).
- Reluctance or inability to explain post-acquisition operational plans.
For sellers, the exposure doesn’t end at closing. "An improperly structured transaction can expose a seller to consequences that outlast that closing," Heath added.
Platforms like Highway have developed carrier identity verification tools to validate the person representing a carrier’s MC is authorized to do so and flagging suspicious ownership changes in real time.

What’s the mechanics of a clean deal?
For carriers looking to legally engage in M&A, the starting point is the sale structure. In a stock sale, Heath explained that the buyer acquires the entity itself—the USDOT number and authority stay attached as the company hasn’t changed, only its ownership has, with operations continuing.
In an asset sale, more common in transactions under $20 million, authority does not transfer automatically. Both parties must notify FMCSA and document the transaction. Heath described it as “a procedural layer that can create timing problems at closing if not planned for.”
Eddie Zukowski, director at PMCF Investment Banking, explained the tax implications: “Asset sales tend to favor buyers and create higher tax burdens for sellers, while stock sales are generally more tax-efficient for sellers but can present tax and liability concerns for buyers.”
Zukowski pointed to F-reorganizations as a structure increasingly used to leverage both the tax and authority areas. Legally structured as stock sales, they allow buyers to elect asset tax treatment, while preserving regulatory continuity.
This gives both buyer and seller the opportunity to optimize their tax outcome, which Zukowski said requires careful upfront planning with M&A advisors and legal and tax professionals.
Carrier size adds another layer
In larger transactions involving multiple entities, Zukowski said a comprehensive regulatory audit should map each USDOT number and MC authority, filing to clarify what is being acquired, and eliminating redundancies across the company.
Heath added that contract re-execution risk is “one of the most under-appreciated sources of deal friction in asset purchases.” For a mid-size regional carrier, individually renegotiating dozens of customer and vendor agreements means each one carries its own timeline and risk of attrition.
What are common mistakes and pitfalls?
The most consistent source of post-close dispute is that buyers often do not realize the gap between what they are told during a deal and what exists in open claims and contingent exposure, Heath said.
“The regulatory register shows reported incidents, it does not show what is being actively litigated,” Heath explained. “That gap is one of the most consistent sources of post-close dispute we encounter, and dedicated insurance due diligence—reviewing open claims—is work that often gets compressed under deal pressure and shouldn’t be.”
Gaps in driver qualification files also become the buyer’s compliance problem after close, he noted, adding that carriers relying on owner-operators carry misclassification exposure.
Safety culture also deserves as much attention, Heath said. It’s worth looking into whether hiring and safety functions have independent reporting lines. “When those lines collapse into a single chain of command, the cultural and compliance risk tends to follow," he said.
What does a typical transaction timeline look like?
A typical full-scale transaction runs eight to 10 months, with Zukowski noting two months of preparing materials, six to eight months engaged with buyers, with the final 60 days concentrated on confirmatory diligence and regulatory filings.
The transportation M&A market is specialized that generalist intermediaries are a liability, Zukowski and Heath agreed. A generalist is unlikely to know what a suspicious buyer profile looks like and recognize warning signs.
