This carrier's address and phone are shared with 5 other carriers — the same officer/phone/address running under multiple authorities is the strongest double-brokering tell. One carrier sharing this phone has been revoked or is out-of-service — the dispatch-shell (call-center) pattern cargo-theft rings use.
A truck VIN on this carrier appeared under 18 different DOTs with only a brief, single-inspection window overlap — usually a legitimate equipment transfer, lease, or roadside data-entry artifact rather than a cloned truck. Verify before drawing a conclusion.
