What WILLIAM ZEPHYR LLC’s FMCSA record shows
Each field from the public registration, and what it means when you’re vetting this carrier.
- USDOT number 3070568
- The USDOT number is FMCSA's permanent ID for this company. It never changes, even when the business renames, moves, or changes owners, so it's the most reliable way to identify WILLIAM ZEPHYR LLC.
- MC number None on file
- No MC number is on file. That's normal for private fleets hauling their own goods and for intrastate-only carriers, but a company with no MC number can't legally haul regulated interstate freight for hire.
- Operating status Active
- FMCSA lists this USDOT number as active. Active status alone doesn't confirm current insurance or operating authority; those are separate checks.
- Operation type Intrastate
- Intrastate carriers are registered to operate within a single state. Booking one for a load that crosses state lines is a compliance red flag.
- Fleet size 0 power units
- WILLIAM ZEPHYR LLC reports no trucks or tractors on its MCS-150 filing. A registration with no equipment is often dormant, so confirm the company is actually operating before booking a load.
- Last MCS-150 update Nov 20, 2017
- The MCS-150 is the registration form where carriers report their address, fleet size, and operations. WILLIAM ZEPHYR LLC last filed it on Nov 20, 2017. That's well past FMCSA's two-year update requirement. Treat the company details on this page as possibly out of date.
