What D SLACK AIR FREIGHT SERVICE’s FMCSA record shows
Each field from the public registration, and what it means when you’re vetting this carrier.
- USDOT number 312544
- 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 D SLACK AIR FREIGHT SERVICE.
- 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 0 power units
- D SLACK AIR FREIGHT SERVICE reports no trucks or tractors on its MCS-150 filing. A registration with no equipment is often dormant, so confirm the company is actually operating before booking a load.
