Operating authority and federal identifiers are strictly regulated. In a recent official release, the Federal Motor Carrier Safety Administration (FMCSA) issued a severe warning to the trucking industry: Do not sell, purchase, rent, or lease a USDOT Number or Operating Authority (MC Number) outside of a legitimate corporate transaction.
Doing so is a direct violation of federal regulations and carries immediate, business-ending consequences.
“The USDOT Number belongs to the same legal person forever and may not be sold, transferred, rented, or leased. FMCSA will inactivate USDOT Numbers upon discovery that the number is being used by anyone other than the assigned legal person.” — FMCSA Official Guidance.
USDOT and MC Numbers are not commodities. They are federal safety identifiers bound to a specific legal entity. Because operating authority is tied directly to an entity’s safety record and management oversight, transferring these numbers to bypass poor safety histories or avoid the new-entrant vetting process is strictly prohibited.
How the Rule Applies to Business Structures:
Sole Proprietors: If you operate as a sole proprietor (e.g., John Doe d/b/a Doe Trucking), your USDOT Number is yours for life. If you sell your business or retire, the buyer must obtain their own USDOT Number. You cannot sell your number to them.
Corporations: In a corporate merger or acquisition, a USDOT Number can only transfer if the motor carrier operations will continue under the exact same safety management oversight and controls. If a completely new entity is formed, new operating authority is required.
Note: Standard equipment leasing arrangements between motor carriers and owner-operators remain perfectly legal and are entirely separate from the prohibited leasing of federal authority numbers.
Before considering any pre-owned vehicle, obtain a vehicle history report. These reports can reveal crucial information about the car’s past, including accidents.
The FMCSA is actively monitoring for fraudulent transfers and unauthorized use of operating authority. There are no warnings and no grace periods.
If the FMCSA discovers that a USDOT or MC Number was purchased, sold, or leased outside of an approved corporate transaction, the agency will take the following immediate actions:
Immediate Inactivation: The USDOT Number will be inactivated the moment unauthorized use is discovered.
Total Revocation: All related safety registrations and operating authorities will be permanently revoked.
Out-of-Service (OOS): Any driver caught operating under a purchased or leased number will be placed out-of-service immediately, potentially leading to criminal fraud referrals.
If you are buying an established USDOT Number from a third party online, you are not buying a clean slate—you are buying an enforcement target. Always apply for your own authority directly through the FMCSA.
