How MC Authority Works: MC Number vs. USDOT Number

MC authority is federal permission to perform a specific type of for-hire interstate transportation. It is not a general trucking license, and it is not the same thing as a USDOT number.

For a typical trucking company, the simplest distinction is this:

• The USDOT number identifies the motor carrier for safety registration, inspections, crash data, and compliance monitoring.
• The operating authority identifies the for-hire service the company is legally allowed to provide. Motor-carrier authority is commonly associated with an MC docket number.

A carrier may have a USDOT number without MC authority. A private fleet hauling its own goods is a common example. A for-hire carrier hauling federally regulated property owned by other people across state lines usually needs both.

USDOT number vs. MC authority

Do not use “DOT authority” and “MC authority” as if they mean the same thing. The distinction matters when checking a carrier, signing a broker agreement, or deciding whether a load can legally move.

Who generally needs MC authority?

FMCSA says companies generally need interstate operating authority when they:

• Transport federally regulated commodities owned by others for compensation in interstate commerce.
• Transport passengers in interstate commerce for compensation, whether the compensation is direct or indirect.
• Arrange regulated interstate transportation as a broker or freight forwarder.

Interstate commerce can exist even when the truck never crosses a state line. If the shipment is part of a continuous movement that originated outside the state or is destined outside the state, federal interstate rules may still apply.

Who may not need MC authority?

FMCSA identifies several common exceptions:

• Private carriers transporting their own property rather than hauling for the public.
• For-hire carriers hauling only exempt commodities, such as certain unprocessed agricultural commodities.
• Carriers operating only inside certain federally designated commercial zones.
• Intrastate-only carriers whose shipments are not part of interstate commerce, although state authority may be required.

Exempt-commodity analysis can be technical. A carrier that sometimes hauls exempt produce and sometimes hauls regulated general freight cannot treat the whole operation as exempt. Review the actual commodity and movement, not the company's preferred label.

The main types of operating authority

The authority must match the service. Common categories include:

Motor Carrier of Property, except Household Goods

This is the standard authority for a for-hire carrier transporting regulated property for the public. The carrier takes responsibility for the physical transportation. FMCSA requires a public-liability filing; federal cargo insurance is not required for this authority, although customers normally expect cargo coverage.

Motor Carrier of Household Goods

This applies to a for-hire mover transporting household goods and offering services associated with a household move. FMCSA requires public-liability and cargo filings, and household-goods consumer-protection rules also apply.

Broker of Property

A broker arranges transportation by an authorized motor carrier and does not take possession of the freight. Broker authority is not permission to operate trucks as a motor carrier. Brokers must maintain the required $75,000 financial security through an eligible bond or trust arrangement, and 2026 rules added protections related to the availability of those funds.

Freight Forwarder

A freight forwarder assembles or consolidates shipments, assumes responsibility for transportation from receipt to destination, and uses carriers for part of the movement. It is a different legal role from a broker.

Passenger, Mexico-domiciled, and other specialized authorities have separate requirements.

How to get MC authority in 2026

1. Determine the correct registration

Use FMCSA's USDOT Wizard and authority descriptions. Read the cargo and service definitions before filing. FMCSA does not refund a fee for an authority selected by mistake.

2. Apply through Motus

FMCSA launched Motus in May 2026 as the system for new USDOT and operating-authority applications and registration management. The company official creates an individual profile, completes identity verification, creates or claims the company account, and submits the registration action.

The permanent-authority fee is $300 for each authority requested.

3. Receive the docket number and monitor the application

Motus randomizes new USDOT and docket numbers as a fraud-control measure. For new authorities, Motus issues one docket number per authority. Existing docket numbers remain unchanged.

The application is not active at this stage. Monitor the status and agency notices for missing information or vetting requests.

4. Have the required insurance or financial security filed

The insurer, surety company, or authorized financial-responsibility filer submits the applicable filing to FMCSA. A certificate handed to a broker does not replace the filing in FMCSA's system.

For a general-freight motor carrier operating a vehicle rated at 10,001 pounds or more, the federal public-liability minimum is commonly $750,000. Many contracts require $1 million. Hazardous materials, passengers, household goods, brokers, and freight forwarders have different requirements.

5. File the BOC-3

The BOC-3 designates process agents who can receive legal documents for the company. For a motor-carrier applicant, only a process agent may file it on the carrier's behalf. Brokers and freight forwarders without commercial motor vehicles may file on their own behalf.

6. Wait for the authority to become active

FMCSA will not grant authority until the applicable financial-responsibility and process-agent requirements are met. Straightforward applications have commonly taken about 20 to 25 business days; vetting may add two to eight weeks or longer.

Check the public record. The authority must show an active status before the carrier transports regulated property for hire under it.

What MC authority does not cover

Active authority does not replace:

• A USDOT safety registration.
• Commercial auto, cargo, general-liability, workers' compensation, or other insurance appropriate to the business.
• UCR, IRP, IFTA, Form 2290, state permits, or plates.
• A CDL or qualified driver.
• Hours-of-service and ELD compliance.
• Driver qualification, drug and alcohol, maintenance, inspection, accident, or cargo-securement programs.
• Broker or freight-forwarder authority if the business performs those separate roles.

Authority answers “may this entity provide this regulated service?” It does not answer every question about whether the truck, driver, route, or load is compliant.

Keeping MC authority active

The carrier must continuously maintain the required insurance and BOC-3 filings. An insurer's cancellation notice can begin a revocation process. Update legal name, address, company information, and the USDOT biennial filing on time.

Also monitor:

• Motus account notices and agency letters.
• Public authority status.
• Insurance renewal and filing dates.
• BOC-3 accuracy.
• UCR renewal.
• Safety performance and out-of-service orders.

FMCSA's 2026 Motus launch did not eliminate MC, MX, or FF docket prefixes. The agency says the possible future elimination of docket numbers remains under consideration and would require a public rulemaking process.

Common MC authority mistakes

• Operating on the number instead of the status. A docket number can exist while authority is pending, inactive, revoked, or suspended.
• Assuming a USDOT number includes authority. It does not.
• Buying an “aged MC.” FMCSA warns that USDOT numbers and operating authority may not be sold, purchased, or leased. A legitimate corporate transaction and compliant equipment lease are different legal issues and require proper filings.
• Using someone else's authority informally. Leasing on requires a compliant written lease and operation under the authorized carrier's control; it is not permission to borrow a number.
• Letting insurance filings lapse. The policy and the FMCSA filing must remain in effect.
• Applying for extra authority “just in case.” Each authority has a fee and can create additional insurance or regulatory obligations.
