1. Searching by USDOT Number

To look up a USDOT number, enter the numerical digits directly into the TransportTrace search bar or the FMCSA SAFER Company Snapshot portal. The system retrieves official census data from the Department of Transportation.

Always verify that the legal business name and physical address match the company on your contract or bill of lading.

2. Key Fields to Review

When examining a USDOT record, pay close attention to the following regulatory indicators:

  • Operating Status: Look for 'AUTHORIZED FOR Property' or 'ACTIVE'. Avoid carriers marked 'INACTIVE' or subject to an Out-of-Service order.
  • MCS-150 Outdated Date: Indicates when the carrier last submitted their mandatory biennial census update.
  • Power Units and Drivers: Gives context on fleet size. For example, a pure broker will often show 0 power units.
  • Cargo Classifications: Confirms whether the carrier is authorized for general freight, motor vehicles, or specialized commodities.

Frequently Asked Questions

What if a USDOT number shows 0 power units?
