How to Read an FMCSA MC Operating Authority Snapshot Before Tendering Freight
Docket numbers prefixed with MC, MX, or FF govern for-hire interstate commerce. Before dispatching a load, shippers and freight brokers should verify three core authority and payment signals:
1. Common Carrier vs. Broker-Only Status
Always verify that Common Carrier or Contract Carrier authority is active. If an MC number holds only Property Broker authority (backed by a $75,000 BMC-84 surety bond rather than BMC-91X primary auto liability), that company cannot legally haul freight on its own trucks.
2. 30-Day MCS-150 Contact Changes
When an established MC number shows a sudden Form MCS-150 update changing its registered phone to a virtual VoIP line or switching from a company domain to a free webmail address, run a shipment packet check to view the prior phone number on file and verify directly with the original fleet owner.
3. UCC § 9-406 Double-Payment Exposure
If a load is unauthorizedly re-brokered, the actual hauling motor carrier—or its factoring company under Uniform Commercial Code § 9-406—can demand payment directly from the shipper even after an intermediary was paid. Cross-check W-9 and Factoring NOA remittance domains on every new carrier packet.
MC Number Lookup FAQs
What is the difference between FMCSA Motor Carrier authority and Broker authority?
An active Common or Contract Motor Carrier authority licenses a company to physically operate commercial trucks and haul interstate freight. A Property Broker authority only permits arranging transportation through third-party carriers. Tendering a physical truck load to a Broker-only MC number exposes shippers to unauthorized re-brokering.
Why does Carrier7 display the masked registered email domain on an MC number lookup?
While the legacy FMCSA SAFER HTML page hides the carrier email address, federal census records include the domain registered by the fleet. Displaying a masked pattern such as s***[email protected] lets dispatchers spot lookalike sender domains without exposing fleet inboxes to bulk spam.
Does an active BMC-91X filing on an MC number mean my cargo is insured?
No. Form BMC-91X covers public bodily injury and property damage (auto liability) to third parties on the highway. Since 2011, FMCSA no longer requires general freight carriers to file Motor Truck Cargo (BMC-34) policies. Always inspect the carrier ACORD 25 COI and call the verified insurance agency switchboard to confirm Cargo limits and exclusions.
