MCS-150 updated
FMCSA's file dates the update November 3, 2026
Why it may matter: Carriers must update the MCS-150 every two years. A fresh update means the fleet and contact details are recent.
What it doesn't show: The MCS-150 is filled in by the company itself; FMCSA doesn't check the numbers.
Next step: Nothing needed unless other details changed too.

First seen in FMCSA's census file
FMCSA lists this USDOT as added October 30, 2026
Why it may matter: A newly listed USDOT number is often a new company. New companies have little inspection or payment history yet.
What it doesn't show: This is the night THC first saw the record. It is not the registration date unless FMCSA's add date says so.
Next step: Check whether operating authority is active and insurance is on file before working together.

Dates are when THC noticed the change in FMCSA's files, not when it happened, unless FMCSA's file gives the date. FMCSA's files can lag behind FMCSA's own systems. Check this record on FMCSA SAFER · Daily FMCSA change reports
