Free, no signup. Refreshed daily from FMCSA.
Brokers lose money two ways with new carriers: tendering to one who can't legally haul, and tendering to one who's been double-brokered onto. KnowHaul returns verified authority, current insurance, observed equipment, and fraud signals in one card so you can rule out both in under a minute, with no per-search fee.
Type a DOT or MC number into the search box on the homepage. We return operating-authority status, current insurance, equipment footprint, recent inspection activity, and any fraud signals — joined into one card and refreshed daily.
Every KnowHaul check pulls four signals in parallel. None of them depend on the carrier filling out a form — they come from public-domain carrier filings and our own inspection-driven inference.
| Signal | What it tells you | How we derive it |
|---|---|---|
| Operating authority | Whether the carrier is authorized to haul today | Public registry, refreshed daily |
| Insurance status | Active vs lapsed liability and cargo coverage | Latest insurance filings on record |
| Equipment footprint | Power units + trailers actually observed on the road | Roadside inspections, VIN-decoded |
| Fraud signals | Double-broker risk, dormancy, identity-flip patterns | Internal rules engine |
There are two ways to verify a carrier with KnowHaul.
| Method | When to use it | Latency |
|---|---|---|
| Single-carrier lookup | You have one DOT/MC to verify before a tender | <1 second |
| Lane-driven leads | You want a ranked list of carriers running a specific lane | <2 seconds |
Every field on KnowHaul traces back to a primary source. We don't aggregate from other broker tools or rely on carrier self-reporting. Specific source provenance is available to customers and regulators on request.
Most broker carrier-check tools either charge per query (CarrierWatch, MyCarrierPackets) or ship a thin re-skin of a free public lookup. KnowHaul is built for brokers who need to run dozens of checks a day without burning $5 each.
Single-carrier lookups are free with no per-search fee. Contact us if you need bulk or API access.
Operating authority and insurance fields refresh daily from authoritative public filings. Inspection-driven fields (equipment, lane footprint) update within an hour of a new roadside inspection posting.
Yes — our rules engine watches for the precursors of double-broker fraud (dormant carriers reactivating, identity flips, address mismatches, freshly-issued MCs claiming established carrier names). Public carrier records won't flag these directly.
No, single-carrier lookups work without an account. Lane-driven leads and saved searches require a free account.
We VIN-decode every power unit and trailer that appears on a roadside inspection. The footprint on each carrier page is the union of equipment observed in the last 12 months.
