What UNITED SITE SERVICES OF MARYLAND INC’s FMCSA record shows
Each field from the public registration, and what it means when you’re vetting this carrier.
- USDOT number 574986
- 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 UNITED SITE SERVICES OF MARYLAND 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 218 power units, 164 drivers
- UNITED SITE SERVICES OF MARYLAND INC self-reports 218 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 Apr 7, 2026
- The MCS-150 is the registration form where carriers report their address, fleet size, and operations. UNITED SITE SERVICES OF MARYLAND INC last filed it on Apr 7, 2026. That's within FMCSA's two-year update requirement, so the company details here are reasonably current.
