What KIRBY-SMITH MACHINERY INC’s FMCSA record shows
Each field from the public registration, and what it means when you’re vetting this carrier.
- USDOT number 581494
- 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 KIRBY-SMITH MACHINERY INC.
- 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 Interstate
- Interstate carriers can haul freight across state lines and fall under the full federal safety rules (FMCSRs).
- Fleet size 222 power units, 220 drivers
- KIRBY-SMITH MACHINERY INC self-reports 222 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 Oct 4, 2024
- The MCS-150 is the registration form where carriers report their address, fleet size, and operations. KIRBY-SMITH MACHINERY INC last filed it on Oct 4, 2024. That's past FMCSA's two-year update requirement. Confirm the address, phone, and fleet size directly.
