USDOT Number Lookup
To look up a DOT number, enter the USDOT in the form on this page. VerifySOS returns the FMCSA record for that number: legal name, operating status, fleet size, and address. If you only have the carrier's name, search by company name and the same lookup returns the USDOT on that record.
What a USDOT number tells you
Every interstate motor carrier, freight broker, and hauler of regulated cargo must register with the FMCSA and carry a USDOT number. The record ties together the carrier's legal name, operating status (active or inactive), power units and drivers, interstate vs. intrastate operation, and principal address.
Why it matters for credit and underwriting
An active USDOT number with a clean operating status is a baseline signal that a carrier is a going concern. An inactive, revoked, or brand-new DOT number is a flag worth a second look before you fund a load, factor an invoice, or open a fuel line. VerifySOS pairs the USDOT/SAFER snapshot with the carrier's Secretary of State record so you see the operating company and the legal entity side by side.
How to look up a USDOT number
You don't need the DOT number to start — type the company name. VerifySOS matches the carrier, confirms the USDOT and (where applicable) MC number, and assembles a verification file with status, fleet, ownership, and addresses, ready to drop in a credit folder.
Frequently asked questions
Is a USDOT number the same as an MC number?
No. A USDOT number identifies the carrier for safety and registration; an MC (motor carrier) number is operating authority for for-hire interstate transport. Many carriers have both.
Is the USDOT lookup free?
Yes — searching and viewing a carrier's USDOT/SAFER summary is free, and so is the verification report (PDF packet): your first 3 searches need no signup and no card, and a free account gets unlimited verification reports through 2026. Pro ($14.99/mo) makes reports unlimited. Owners are included wherever the state publishes them, on every plan.
What does an inactive USDOT status mean?
It means the carrier's registration is not currently active — it may be dormant, revoked, or out of service. Treat it as a flag, not a final answer, and verify the legal entity's standing too.
