The practical problem: you book one company to carry a load, but another company arrives to move it without an agreed handoff. That may be unauthorized re-brokering, carrier impersonation, a permitted subcontract, or simply an equipment arrangement you have not documented. Find out which one before the freight is loaded.
Double brokering is often used to describe an undisclosed second booking of the same load. The exact contractual and legal consequences depend on who arranged transportation, what authority they held, and what the agreements allowed. Disclosed co-brokering is different: the parties agree to the arrangement and its responsibilities up front. Federal law addresses unlawful brokerage in 49 U.S.C. 14916; a mismatched truck alone does not establish a violation of that statute.
Before tender: verify the people, not just the number
- Match the packet’s legal name and USDOT number to the FMCSA Company Snapshot. Check the appropriate authority and status.
- Call a contact you independently found for the carrier, especially when the email, phone number, or payment instructions have changed. A real MC number can be used by someone who does not control it.
- Ask in writing who will move the freight, on whose operating authority, with which driver, tractor, and trailer. Record any approved subcontracting arrangement under your agreement.
- Give the shipper a simple pickup instruction: compare the arriving carrier and equipment with the booking details, and call before loading if they do not match.
Our free risk check can surface public-record inconsistencies. It cannot prove that a carrier will re-broker a future load or that a shared dispatch number is fraudulent.
At pickup: resolve a mismatch
An unfamiliar truck is a reason to stop and verify, not to accuse. Equipment may be leased, a driver may have changed, or a carrier may be using a permitted arrangement. Ask the booking contact and the arriving driver to identify the motor carrier responsible for the load. Check that carrier’s authority and insurance for the movement. Obtain written approval for a changed arrangement before the shipper releases freight.
If the explanation changes or the booked carrier cannot confirm the truck, keep the load on the dock while you contact the shipper and your own risk team. Save the dispatch messages and the names, equipment identifiers, and times involved.
If the load already moved
Establish who actually has the freight and where it is. Notify the shipper, your insurer or claims team, and the contracting parties. Preserve both rate confirmations, bills of lading, delivery records, communications, and payment instructions. Do not send a second payment or hold freight based solely on a blog post. Claims against a broker, its security, a shipper, or another party depend on the facts and applicable law; ask transportation counsel promptly.
Carriers that discover a second booking should preserve their dispatch and delivery evidence, identify who contracted with them, and verify that party’s authority and financial security through FMCSA. FMCSA publishes broker financial-responsibility requirements, including the $75,000 bond or trust requirement. That amount is not a guarantee of recovery on a particular invoice.
You can report suspected misconduct to FMCSA. If cargo is missing or anyone is in immediate danger, contact the appropriate emergency or law-enforcement service.
