Double-broker check — spot fraud before you tender
Paste a DOT or MC number. KnowHaul rolls up dormancy reactivation, domicile-footprint mismatch, implausible fleet growth, and paper-carrier signals into a single fraud verdict — derived from the FMCSA filings, refreshed nightly.
What is double-brokering? How do these signals work?(expand)
Double-broker check — spot fraud before you tender
Double-brokering happens when a carrier re-tenders your load to someone else without permission — usually to a freshly-issued MC with no track record. By the time the cargo is missing, the original MC is already dormant. KnowHaul checks every name and DOT against the patterns we see in real double-broker incidents: MC reuse, identity flips, dormant authority that reactivated in the last 90 days, and physical-address mismatches.
Quick Answer
Type the carrier's name, DOT, or MC into the search box. KnowHaul cross-checks the MC against four fraud-precursor patterns in under a second and surfaces a risk verdict alongside the carrier's authority, insurance, and inspection footprint.
What double-brokering actually looks like
Double-brokering isn't an exotic crime ring — most cases are a small carrier or dispatcher with a phone, a clean-looking MC, and a willingness to re-tender. The cargo is usually electronics, tires, or food-grade freight that liquidates fast. The broker doesn't find out until the consignee calls asking where their truck is.
Three patterns we see weekly
Fraud signals we watch for
KnowHaul's rules engine scores every MC against signals that public FMCSA records don't combine for you. None of these are individually conclusive — they're precursors. The verdict combines all of them with the carrier's own inspection record.
| Signal | Why it matters | How we derive it |
|---|---|---|
| MC age | Brand-new MCs are over-represented in confirmed double-broker incidents | FMCSA registration date vs today |
| Dormant-then-reactivated | A reactivated authority is the easiest way to skip a fresh review | Authority history from the L&I register |
| Identity-flip pattern | Same physical address + new legal name = a likely re-shell | Address + name overlap across FMCSA registrations |
| Address mismatch | Carriers re-brokering loads often answer from a virtual office | Cross-reference FMCSA address vs phone area code + inspection state |
| Equipment vs cargo claim | A carrier with zero reefers shouldn't be booking refrigerated lanes | VIN-decoded equipment from roadside inspections |
Why public records won't flag this directly
How to run a check on a tender
There are two ways to verify a carrier before a tender. The single-carrier check is the right call for almost everyone; the bulk export is for brokers running 100+ tenders a day.
| Method | When to use it | Latency |
|---|---|---|
| Single-carrier lookup | You have one MC to vet before tendering this load | <1 second |
| Lane-driven shortlist | You want to start from carriers that already run your lane | <2 seconds |
What FMCSA's own data doesn't flag
OP-1 enforcement is improving, but the gap brokers care about is real-time: FMCSA can take 30–90 days to update a carrier's status after a complaint. KnowHaul fills that gap by computing the precursor patterns from the raw filings the same day they post, rather than waiting for an enforcement verdict.

Pro Tips
- Treat any MC under 90 days old as elevated risk. Not all new MCs are bad actors — but every confirmed double-broker incident we've reviewed involved an MC less than three months old. Ask for a second proof of operation before tendering.
- Confirm the dispatcher's email domain matches the legal name. Free email domains (gmail, outlook, yahoo) are common for legitimate small carriers, but a domain that doesn't match the company name AND a brand-new MC is the highest-correlation pair in our incident data.
- Cross-check the phone area code against the FMCSA physical address. Re-brokering operations frequently answer from a number whose area code doesn't match the registered address state. It's not conclusive on its own — combined with one other signal, it's worth a callback.
Frequently Asked Questions
What is double-brokering?
Double-brokering is when a carrier tendered a load by a broker re-tenders that load to a different carrier without authorization. The cargo ends up under the control of a party the original broker has not vetted and has no contract with, which is the mechanism behind most modern freight-theft cases.
Is double-brokering illegal?
Re-brokering a load without proper broker authority is a violation of FMCSA regulations and exposes the carrier to OP-1 enforcement. FMCSA has been increasing penalties since 2023, but the enforcement gap (30–90 days) is wide enough that real-time vetting is still the only reliable defense.
Can KnowHaul guarantee a carrier won't double-broker?
No — and any tool that claims to should be treated with suspicion. What we can do is surface the precursor patterns we see in confirmed incidents (MC reuse, identity flips, dormant reactivations, address mismatches) so you can make an informed call before tendering. A clean verdict means we couldn't find any of the high-correlation precursors, not that the carrier is incapable of fraud.
How fresh is the fraud-signal data?
Authority status, insurance filings, and registration changes refresh within 24 hours of the public filing posting. Inspection-driven signals (equipment footprint, lane activity) refresh within the hour. We don't rely on a third-party fraud feed — every signal is derived from primary FMCSA data.
Do I need an account to run a double-broker check?
No. Single-carrier double-broker checks are free with no per-search fee or signup. Bulk export and API access (for brokerages running 100+ tenders/day) require an account.
