Someone messages you offering cash for your MC number, or to rent or lease it. FMCSA’s bulletin of March 13, 2026 answers that directly:
“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.”
The same bulletin states that “The USDOT Number belongs to the same legal person forever and may not be sold, transferred, rented, or leased.” When FMCSA discovers attempts to sell, purchase or lease a USDOT number or operating authority outside a legitimate corporate transaction, it says it “will initiate proceedings to inactivate the USDOT Number and revoke all related registrations”.
In FMCSA’s terms, the number stays with the legal person it was assigned to. What changes hands in a real sale is that company. If you are not sure which side of the line your situation falls on, the can my MC be sold checker walks through it in six questions.
