A carrier that passes every check can still hand your load to someone you've never vetted. Here's what double brokering actually is, the warning signs before you award, and what to do if you think it's already happening to a shipment in transit.

The load looked fine on paper. Verified DOT number, active authority, a rate that matched the market. Then the truck that showed up at pickup wasn't the one whose name was on the rate confirmation — and two days later nobody at the original carrier would answer the phone. That's double brokering, and it's the version of freight fraud that a basic carrier check doesn't catch, because the carrier you checked was often real. It just wasn't the one that actually ran your freight.
A carrier accepts your load, then re-brokers it to a second, unvetted carrier without telling you — and often without a written agreement covering who's liable if something goes wrong. The company you awarded collects the spread between what you paid and what they paid the second carrier, and disappears from the transaction the moment the freight is picked up. In the more damaging version, the second "carrier" was never a real business at all: it's a cargo theft operation using a stolen or fabricated identity, and the freight doesn't arrive anywhere near its destination.
This is different from legitimate interlining or a disclosed co-broker arrangement, where everyone involved knows who's actually hauling the freight and liability is spelled out in advance. The problem isn't that more than one company touched your load. It's that you awarded a load to Company A, and Company B — a company you never vetted, never approved, and may not even be able to identify — is the one that showed up.
A growing share of double brokering cases involve criminals using a real, legitimate carrier's MC number and DOT authority — stolen off a public FMCSA record — to bid on and win loads that the actual carrier never bid on and knows nothing about. You can check the DOT number and it comes back clean, because it belongs to a real, compliant carrier. It's just not the one you're actually dealing with.
When a box truck is the right equipment, what to put in the load post so carriers can bid properly, where to find box truck carriers, and the factors that move the price. No invented rates.
A shipper checklist for comparing carrier bids: what the rate includes, who the carrier is, what the insurance and safety record show, and when the lowest bid is not the best one.
Skipping the broker removes a fee, but only if you do the rate-checking and vetting a broker used to do for you. Here's what posting loads directly to approved carriers actually costs, the cheapest path step by step, and when skipping the broker is the wrong call.
Post a load or bid on freight — free to start.
Get started freeSpot rates have been thin for stretches of the last few years, which puts pressure on anyone willing to flip a load for a quick margin instead of running it. At the same time, a lot of freight is still booked over the phone or by email with no persistent, verifiable identity behind the person on the other end of the call — just a name, a number, and an MC that may or may not belong to whoever's actually talking to you. That combination is exactly what makes this scam easy to run at scale.
Contact information that doesn't match FMCSA's record. If the phone number or email chasing your load isn't the one on file for that carrier's registered authority, that's worth a direct call to the number FMCSA has, not the one you were given.
Reluctance to name the truck or driver before pickup. A real carrier running your freight themselves can tell you which truck and which driver is coming. Vague answers, or answers that change the day of pickup, are the clearest signal something is being re-routed behind the scenes.
A last-minute substitution "because our truck broke down." Sometimes that's exactly what happened. It's also the standard cover story for handing a load to a second, unvetted carrier after the fact — the request to swap should trigger the same vetting the original carrier went through, not a pass.
An insurance certificate that doesn't check out when you call the insurer directly. Not the number on the certificate's letterhead — the insurer's actual main line, found independently.
A winning bid that's unusually low even in a competitive field. Underbidding a pool of legitimate carriers only makes sense if you're planning to run the freight yourself. If the plan is to flip it to someone cheaper and pocket the difference, bidding low to win first is the whole strategy.
No platform makes this fraud technically impossible — a criminal with a convincingly stolen authority can still get past an initial check, on any system. What a bidding marketplace can do is remove the easiest version of the scam and leave a paper trail if the harder version is attempted anyway.
Carriers are FMCSA-verified before they can bid at all — active operating authority, insurance on file, and safety rating confirmed, the same pipeline covered in the carrier vetting guide. That's the gate a stolen-identity carrier has to clear before ever reaching your load, not after.
The carrier who bid is the carrier of record, named on the rate confirmation and the bill of lading, with dispatch and shipment tracking tied to that specific company — not a phone number that can be handed to someone else after the award.
The carrier directory (browse verified carriers) shows verification status, DOT and MC numbers, and review history from other shippers before you ever award a load — reputation you can check independently of whatever the bid itself says.
Location tracking carries its own provenance. A position update on an active shipment is marked as either a real GPS fix or a manually typed entry, so a shipment reporting from an inconsistent location, or going quiet at a point where it shouldn't, is visible rather than buried in a single "in transit" status with no detail behind it.
Don't release payment until delivery is confirmed against the paperwork, by the actual consignee, not a status update from the carrier. Call the insurer directly — using the number from their own public listing, not one the carrier gave you — and confirm the certificate is real and active today, not just real at some point in the past. Ask the driver for identification at pickup or delivery and confirm it matches the company you actually awarded the load to. If something comes back wrong, this moves from a business dispute to a police matter: report it to FMCSA and to local law enforcement, and loop in your cargo insurer immediately rather than waiting to see if the freight turns up.
No shipper can get this risk to zero, and anyone who tells you otherwise is selling something. What reduces it to a manageable level is stacking verification that happens before the bid, reputation you can check independently of the bid, and a paper trail that names a specific accountable company rather than a phone number. That's the combination worth insisting on, whichever platform you're shipping through.
Post your first load free and see the FMCSA-verified carrier bidding on it before you award anything.
