Each field from the public registration, and what it means when you’re vetting this carrier.
- USDOT number 3113356
- 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 MASON DIXON ENERGY SERVICES LLC.

- An MC (docket) number means the company applied for interstate operating authority to haul regulated freight for hire or to broker loads. Brokers and shippers usually check MC authority before booking.
- 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 Interstate
- Interstate carriers can haul freight across state lines and fall under the full federal safety rules (FMCSRs).
- Fleet size 106 power units, 87 drivers
- MASON DIXON ENERGY SERVICES LLC self-reports 106 power units (trucks and tractors), which makes it a large fleet. Fleet counts come from the carrier's own MCS-150 filing and aren't independently audited.
- Last MCS-150 update Aug 8, 2025
- The MCS-150 is the registration form where carriers report their address, fleet size, and operations. MASON DIXON ENERGY SERVICES LLC last filed it on Aug 8, 2025. That's within FMCSA's two-year update requirement, so the company details here are reasonably current.
