What SOUTHERN PIPE & SUPPLY CO INC’s FMCSA record shows

Each field from the public registration, and what it means when you’re vetting this carrier.

USDOT number 79183
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 SOUTHERN PIPE & SUPPLY CO INC.
MC number MC 781961
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 269 power units, 362 drivers
SOUTHERN PIPE & SUPPLY CO INC self-reports 269 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 Mar 20, 2026
The MCS-150 is the registration form where carriers report their address, fleet size, and operations. SOUTHERN PIPE & SUPPLY CO INC last filed it on Mar 20, 2026. That's within FMCSA's two-year update requirement, so the company details here are reasonably current.
