If you’ve been approached about selling your USDOT or MC number, federal regulators are making it clear: don’t do it. A recent bulletin from the Federal Motor Carrier Safety Administration (FMCSA) is calling attention to a growing problem that could put carriers and owner-operators at serious risk.
Released March 13, the agency’s message was direct:
“DO NOT Sell, Purchase, or Lease a USDOT Number or Operating Authority (MC Number) online or elsewhere from an unknown person or outside of a legitimate corporate transaction.”
Why USDOT and MC Numbers Matter
For anyone running under their own authority, a USDOT number isn’t just paperwork. It functions much like an identification number that ties your entire operation to a single legal entity. Whether you’re hauling under your own name or operating as a larger carrier, that number is how regulators track safety records, inspections, and compliance.
According to FMCSA, that connection cannot be separated or reassigned informally.
“The USDOT Number belongs to the same legal person forever and may not be sold, transferred, rented or leased,” the agency wrote in the bulletin. “FMCSA will inactivate USDOT Numbers upon discovery that the number is being used by anyone other than the assigned legal person.”
What Happens If You Ignore the Rule
This isn’t a gray area. If FMCSA finds out that a USDOT or MC number is being bought, sold, or leased outside of a proper business transaction, the consequences can shut an operation down fast.
The agency states it will move to deactivate the number and revoke any associated registrations tied to that authority. For drivers and fleets, that means loads stop, revenue disappears, and rebuilding compliance can take time.
Real-World Risk for Owner-Operators
The warning isn’t just theoretical. Industry groups are already seeing the fallout.
Owner-Operator Independent Drivers Association (OOIDA) says improper transfers have created major legal and financial headaches for drivers.
Brittany Murphy, an agent in OOIDA’s Permits and Licensing Department, shared an example of an owner-operator who sold his authority. Years later, a crash involving the carrier operating under that same number led to the original owner being held responsible because the transfer wasn’t completed correctly.
That kind of situation can expose drivers to liability long after they think they’ve moved on from a business.
Understanding Legitimate Transfers
There is a difference between selling a company and trying to sell a number. FMCSA recognizes that operating authority can change hands as part of a legitimate corporate transaction, such as selling a business entity.
The key is that the legal structure must transfer properly. Simply handing off a USDOT or MC number without completing the correct process does not count as a valid transfer in the eyes of regulators.
The agency also outlines differences between sole proprietors and corporations, which can affect how authority is handled during ownership changes.
What Drivers Should Do Now
If you’ve ever transferred or sold your authority, it’s worth double-checking that everything was completed correctly. Even if the deal happened years ago, your name could still be tied to that number if the paperwork wasn’t finalized through proper channels.
OOIDA advises drivers with questions to contact its Permits and Licensing Department at 816-229-5791 for guidance.
Bottom Line for the Industry
Shortcuts around compliance rarely stay hidden for long. As enforcement tightens, regulators are watching more closely for misuse of USDOT and MC numbers.
For drivers, owner-operators, and fleet managers, the takeaway is simple: your authority is tied to your identity. Treat it that way, and make sure any transition is done by the book.
