What WALTER STAPLETON’s FMCSA record shows
Each field from the public registration, and what it means when you’re vetting this carrier.
- USDOT number 2575327
- 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 WALTER STAPLETON.
- 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 1 power unit, 1 driver
- WALTER STAPLETON self-reports 1 power unit (trucks and tractors), which makes it an owner-operator. Fleet counts come from the carrier's own MCS-150 filing and aren't independently audited.
- Last MCS-150 update Mar 6, 2015
- The MCS-150 is the registration form where carriers report their address, fleet size, and operations. WALTER STAPLETON last filed it on Mar 6, 2015. That's more than ten years old, so the company details here are essentially unverified.
