Each field from the public registration, and what it means when you’re vetting this carrier.
- USDOT number 18490
- 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 BUILDERS SUPPLY CO 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 Inactive
- FMCSA lists this USDOT number as inactive. Inactive carriers shouldn't be dispatched; confirm the company has reactivated before booking a load.
- Operation type Interstate
- Interstate carriers can haul freight across state lines and fall under the full federal safety rules (FMCSRs).
- Fleet size 39 power units, 40 drivers
- UNITED BUILDERS SUPPLY CO INC self-reports 39 power units (trucks and tractors), which makes it a mid-size fleet. Fleet counts come from the carrier's own MCS-150 filing and aren't independently audited.
- Last MCS-150 update Aug 3, 2017
- The MCS-150 is the registration form where carriers report their address, fleet size, and operations. UNITED BUILDERS SUPPLY CO INC last filed it on Aug 3, 2017. That's well past FMCSA's two-year update requirement. Treat the company details on this page as possibly out of date.
