Why it may matter: An inactive USDOT number should not be used for interstate commercial trucking.
What it doesn't show: USDOT status is not operating authority. An active USDOT can still have no active MC authority.
Next step: Run a live check, and confirm with the company using the phone number on its FMCSA record.

First seen in FMCSA's census file
FMCSA lists this USDOT as added October 29, 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
