Double brokering is one of the most damaging fraud schemes in freight — and it's growing. A double broker takes your load, re-brokers it to another carrier without your knowledge or permission, pockets part of the rate, and leaves you exposed when something goes wrong. The good news: FMCSA data reveals the warning signs before you book. Here's exactly how to spot them.
Double brokering is illegal. Under 49 U.S.C. § 13901, re-brokering a load without authorization is a federal violation. It also voids your cargo insurance and leaves you with no recourse if the freight is lost or damaged.
What Is Double Brokering?
Double brokering happens when a carrier or broker accepts your load and then secretly re-brokers it to a third party — typically at a lower rate — without telling you. The middleman pockets the difference. The actual carrier transporting the freight doesn't know you're the original shipper, and you don't know who's really moving your freight. When something goes wrong — damaged cargo, a stolen load, a payment dispute — you're left with no legal recourse against the actual carrier.
Double brokering often involves identity theft: criminals steal a real carrier's DOT number and MC number, then pretend to be that carrier while secretly sub-contracting to another truck. The FMCSA data doesn't lie — here's how to use it to catch them.
Warning Sign #1 — Authority Registered Very Recently
Fraudulent carriers frequently register new FMCSA authority for the sole purpose of committing a single fraud before disappearing. Look for the "Active Since" date in the carrier's FMCSA record. Any carrier with authority less than 6 months old requires additional verification. Under 30 days is a serious red flag.
Check this instantly on CarrierCheck — the carrier card shows exactly how long the authority has been active: "Active for 2y 4m · since 03/12/2024"
Warning Sign #2 — Contact Info Doesn't Match FMCSA Records
This is the most reliable double brokering indicator. A fraudster using a stolen carrier identity will give you their own phone number and email. When you verify on FMCSA, the contact information will be different — it belongs to the real carrier whose identity was stolen.
Always compare the phone number, email address, and physical address the carrier gives you against what appears in the FMCSA database. Any discrepancy should stop the booking immediately.
Call the phone number shown in the FMCSA record — not the one the carrier gave you. If you reach a different person or company, you've just caught a double broker or identity thief.
Warning Sign #3 — They Cannot Provide an Actual Carrier Packet
A legitimate carrier has a carrier packet ready: W9, certificate of insurance naming your company, signed carrier agreement, and copy of their operating authority certificate. Double brokers and fraudsters either can't provide these documents or provide falsified versions.
Request the certificate of insurance directly from the carrier's insurance agent — not from the carrier. The agent's contact information is in the FMCSA record. If the carrier resists this or offers excuses, walk away.
Warning Sign #4 — Fleet Size Is Inconsistent With Their Claims
A carrier claiming to have 20 trucks available but showing only 1 power unit in their FMCSA record is a red flag. Either their filings are severely out of date — which itself is a compliance problem — or they don't actually own the trucks they claim to operate. Double brokers often claim capacity they don't have because they plan to sub-contract everything anyway.
Warning Sign #5 — Rate Is Suspiciously Below Market
Double brokers make money by accepting your rate and then finding a cheaper carrier to actually move the freight. This means they're often willing to accept rates below what legitimate carriers will move freight for. If a carrier's rate is 15-20% below current market rates with no clear explanation, treat it as a warning sign and verify more thoroughly.
