Carrier vs Broker Authority

Compare carrier and broker authority concepts using official FMCSA and UCR sources.

Quick Answer

Motor carrier authority allows a business to transport regulated freight directly for compensation, while broker authority allows a business to arrange transportation between shippers and carriers — both require FMCSA registration, BOC-3, and UCR, but carriers need cargo and liability insurance while brokers need a surety bond or trust fund.

Authority and registration topics often connect to BOC-3, UCR, and new-authority sequencing. New Authority Checklist, BOC-3, UCR.

Who This Applies To

New entrants who need to decide whether to apply for carrier authority, broker authority, or both before beginning operations.
Existing carriers who want to add broker authority to arrange loads in addition to transporting them.
Businesses that arrange transportation without owning trucks and need to confirm they need broker authority, not carrier authority.
Carriers and brokers who have different MC numbers for different authority types and need to understand the distinction.

What To Verify

That carrier authority (MC number as for-hire motor carrier) authorizes the entity to physically transport freight for compensation. Broker authority authorizes the entity to arrange transportation between shippers and carriers without taking possession of freight.
That a motor carrier cannot legally broker freight unless it also holds active broker authority. Using a carrier MC number to arrange loads the carrier will not haul is a regulatory violation.
That holding both carrier and broker authority requires separate registrations and may require separate BOC-3 filings and surety bonds — confirm the specific requirements with FMCSA and the process agent.
The insurance differences: carrier authority requires liability insurance (BMC-91 or BMC-91X); broker authority requires a surety bond (BMC-84) or trust fund (BMC-85). The amounts and form types differ.

Step-by-Step Overview

Determine what the business will actually do. If the business will physically haul freight with its own trucks, it needs carrier authority. If it will arrange transportation by matching shippers with third-party carriers, it needs broker authority.
Apply for the appropriate authority type through the FMCSA Unified Registration System. If both types are needed, both are applied for separately and may be held simultaneously.
File the appropriate insurance or surety instrument with FMCSA. Carrier authority: BMC-91 or BMC-91X filed by the insurance company. Broker authority: BMC-84 or BMC-85 filed by the surety company.
File BOC-3 through a registered process agent for the authority type being activated. Confirm with the agent whether separate filings are needed for each MC docket.
Confirm in SAFER that the correct authority type shows as active before beginning the relevant operations.

Common Mistakes

Operating as a de facto broker using a carrier MC number. Carriers who arrange loads for other carriers to haul — without separately holding broker authority — are violating FMCSA regulations.
Confusing the surety bond requirement (broker authority) with the liability insurance requirement (carrier authority). They are different instruments with different minimum amounts and purposes.
Not verifying in SAFER that the correct authority type is active. An entity that applied for both may find one activates before the other — check each separately.
Assuming BOC-3 from one authority type automatically covers the other. Carrier and broker authority under separate MC dockets may each require independent BOC-3 filings.

FAQ

Can one entity hold both carrier and broker authority?

Yes. FMCSA allows a single entity to hold both motor carrier authority and broker authority. However, each authority type has separate insurance, bond, and BOC-3 requirements, and some shippers may have policies about dual-authority entities to avoid conflicts of interest.

Can a company hold carrier authority and broker authority at the same time?

Yes. A company can hold separate motor carrier authority and broker authority under different MC numbers simultaneously. Each authority type has its own BOC-3 designation, insurance or surety bond filing, and UCR registration. Managing both requires tracking compliance requirements for each MC number independently — UCR and BOC-3 each apply to the specific authority they cover.

Does a carrier need broker authority to haul loads it booked directly with the shipper?

No. A licensed motor carrier that books and physically transports a load is acting as a carrier, not a broker. Broker authority is required when the entity arranges transportation between a shipper and a third-party carrier without taking possession of the freight. Verify the specific arrangement with FMCSA if the operation blends carrier and brokerage activities.
