Can you buy an established trucking company and keep its authority?
Sometimes, but the answer depends on what you are buying. FMCSA says a USDOT number cannot be transferred to a different legal person. If a corporation is sold and that same corporation continues to operate, its USDOT number stays with the corporation. If the buyer creates a new legal entity, the new entity normally needs its own number.
MC operating authority is different. FMCSA may record a transfer when it is part of a legitimate purchase of an entire operation and both parties document the transaction. A listing that offers only an old DOT or MC number is not a safe substitute for a real acquisition.
Start with the legal entity. Then check the operating record, insurance, registrations and debts. Official references: FMCSA on USDOT numbers and FMCSA transfer guidance.

Why an established authority is not always a shortcut
Due diligence checklist before you buy
1. Identify the legal entity
Confirm whether you are buying assets, stock, LLC interests or a newly formed business. Match the exact legal name, state registration, EIN, USDOT and MC authority.
2. Pull the federal records
Review SAFER, SMS/CSA data and FMCSA Licensing and Insurance. Save the records used for the decision and note any pending or inactive status.
3. Review insurance and claims
Request policies, declarations, loss runs, open-claim details, cancellation notices, filings and certificate requirements. Ask what coverage must be replaced at closing.
4. Verify trucks and trailers
Match titles, VINs, liens, leases, values, IRP cab cards and the actual unit schedule. Confirm which equipment is included and who owns it.
5. Check tax and registration accounts
Verify IFTA returns, IRP status, state tax accounts, tolls, permits and outstanding balances with the agencies that control them.
6. Read the contracts
Review customer, broker, factoring, lease and equipment agreements. Check assignment rules, insurance limits and termination terms.
7. Build the closing plan
List each update, filing, policy, payment and effective date. Assign an owner to every task and do not operate until authority, insurance and registrations are ready.
USDOT number and MC authority are not the same asset
A USDOT number identifies the legal person registered with FMCSA. FMCSA says it belongs to that person and cannot be sold, rented or leased. This is why the purchase structure matters.
An MC number identifies operating authority. FMCSA can record a transfer of operating authority as part of a purchase involving an entire operation. The parties must document the transaction and complete the agency’s process. Insurance and process-agent filings also have to match the post-closing operation.
Check the public record before you negotiate the price:
- SAFER Company Snapshot for identity, status, inspections, crashes and safety rating information.
- FMCSA CSA/SMS for current public safety performance information.
- FMCSA Licensing and Insurance for authority and insurance filing status.
Safety records and insurance claims can change the value of the deal
FMCSA’s Safety Measurement System uses 24 months of roadside inspection violations and state-reported crashes. The data follows the carrier’s USDOT record. A change in owners does not erase the record when the same legal entity continues.
Use the numbers carefully. FMCSA states that SMS percentiles and alerts are not federal safety ratings. They can still show areas that need attention, trigger more monitoring, and shape the work required after closing.
Insurance loss runs answer a different question. They show reported claims, paid amounts, reserves and open files for the periods provided. Ask for enough history to support underwriting and have the seller authorize verification. Review the current policy, cancellation status, deductibles, cargo, physical damage, trailer interchange, general liability and every certificate required by a customer or broker.
If the company has an out-of-service problem, read our out-of-service violation guide. A newer operation should also use the FMCSA new entrant safety audit checklist.
What must be ready before the closing date?
Closing file
Do not use one date for every agency. FMCSA, the IRS, a state IRP office, an IFTA administrator and an insurer each have their own rules. Build the closing plan backward from the date the trucks must operate.
For Illinois-based fleets, the Secretary of State says a change in the USDOT number used as the safety carrier requires an IRP correction. Review the current Illinois instructions and contact the Commercial and Farm Truck Division for the exact documents.

Frequently Asked Questions About Buying an Existing Trucking Company
Clear answers to common questions about Buying an Existing Trucking Company. Open a question to read the answer and source. Last verified: October 26, 2026.
Can I buy another carrier’s USDOT number?
No. A USDOT number cannot be sold or transferred as a stand-alone identifier. FMCSA assigns the number to a specific legal person. If you buy the stock or ownership interests of a corporation and the same corporation continues, the number can remain with that legal entity. A new legal entity normally needs its own USDOT number.
Can an MC operating authority be transferred?
An MC operating authority may be transferred as part of a legitimate purchase of an entire operation. FMCSA requires notice and transaction records from the parties. Buying or leasing an MC number by itself from an unknown seller is not a valid shortcut.
What is the first thing to check before buying a trucking company?
Confirm exactly which legal entity, assets, registrations, contracts and liabilities are included in the deal. An asset purchase and a purchase of corporate ownership can produce different results for the USDOT number, EIN, insurance and regulatory history. Have the transaction structure reviewed before relying on an old authority.

Does the company’s CSA history stay after ownership changes?
If the same legal entity and USDOT number continue, the carrier’s existing FMCSA record does not reset because the owners changed. FMCSA uses inspections and crashes associated with that carrier’s USDOT number. Review the record before closing and build the purchase terms around any problems you find.
How much history does the FMCSA Safety Measurement System use?
SMS uses 24 months of roadside inspection and state-reported crash data. More recent events receive more weight. Check the current public record and ask the seller for supporting documents because not every detail is public.

Is a CSA percentile the same as a federal safety rating?
No. SMS percentiles and alerts are not federal safety fitness ratings. They help FMCSA prioritize carriers for monitoring and intervention. A formal safety rating is a separate determination. Review both the SMS information and the SAFER Company Snapshot.
Source: FMCSA CSA public notice
Should I request insurance loss runs before buying the company?
Yes. Ask for current loss runs and information about open claims before you sign. The record can affect underwriting, deductibles, available markets and the price of coverage. Verify the documents with the seller’s agent or insurer when the seller authorizes release.
Source: Ensure Inc. insurance review guidance.
Will the seller’s insurance policy transfer to me?
Do not assume it will. Coverage depends on the named insured, transaction structure, carrier approval, effective date and underwriting. Arrange the insurance review before closing so the operation does not start with a gap.
Source: Ensure Inc. insurance review guidance. Coverage is subject to insurer underwriting.
Do IRP and IFTA accounts transfer with a trucking company?
Verify each account with the base jurisdiction before closing. The answer depends on the legal entity, account status and state rules. Ask about open returns, balances, decals, plates, vehicle schedules and any required change to the USDOT number or safety carrier.
Source: Illinois Secretary of State commercial and farm truck guidance
Will I need a new EIN after buying a trucking business?
It depends on the entity and the structure of the purchase. The IRS generally requires a new EIN when ownership or entity structure changes, but lists exceptions for some corporations, partnerships and reorganizations. Confirm the answer with a tax professional for the transaction you are planning.
Source: IRS: When to get a new EIN
How long does a trucking company ownership change take?
There is no single timeline for every deal. The time depends on the entity documents, IRS records, FMCSA updates or authority transfer, state registrations, insurance underwriting and whether any records need correction. Set the closing date only after the responsible agencies and professionals confirm their steps.
Source: FMCSA and IRS guidance. Processing times vary by filing and transaction.
When should I call an insurance agent about the purchase?
Call before you sign the purchase agreement or commit to a closing date. Send the target company’s name, USDOT and MC numbers, garaging state, unit count, proposed ownership structure, desired closing date and available loss runs. That gives the agent enough information to identify the first insurance questions.
