How to run a DOT number lookup in 3 steps
Start with the registration. Then follow through on the details that matter for your shipment.
Search by USDOT, MC, or company name

Open the official FMCSA record from each result. Confirm operating authority, insurance, and out-of-service status before booking.
How to find a DOT number by company name
A carrier name is often all a quote or bill of lading shows. The company name search finds the USDOT number from there.
- 1
Use the legal name. Pull it from the carrier's rate confirmation or paperwork. A trade name may not match.
- 2
Start short. Drop suffixes like Inc. or LLC if the first search misses.
- 3
Match the address. Several carriers can share similar names. Confirm the city and state before booking.
Once the USDOT number shows up, run a USDOT lookup for the full carrier record.
USDOT number vs MC number
Most carrier checks start with one of these two numbers. A DOT and MC number lookup together gives the fullest view of a carrier's registration.
| USDOT number | MC number | |
|---|---|---|
| What it identifies | The business, for FMCSA safety oversight | An operating authority docket |
| Who holds it | Carriers running commercial vehicles in interstate commerce | For-hire interstate carriers and brokers |
| Format | Digits only | MC prefix plus digits |
| Search it here | USDOT number tab | MC number tab |
Neither number alone confirms current authority or insurance. Check both on FMCSA before booking.

What is a USDOT number?
A USDOT number is a unique ID that FMCSA assigns to commercial motor carriers. It links the business to its registration, fleet size, and safety record. A USDOT lookup pulls that record by number or name.
What's the difference between a DOT and MC number?
A USDOT number identifies a carrier for safety oversight. An MC number identifies its operating authority docket for for-hire interstate work. Many carriers hold both. Neither number alone confirms current authority or insurance.
How do I find a DOT number by company name?
Select Company name in the search tool and enter the carrier's legal name. Partial names work too. Results list matching carriers with their USDOT number, address, and registration status. Try a shorter name if nothing appears.
How does an MC number lookup work?
Select MC number and enter the docket number. The MC lookup returns the matching carrier's USDOT number and company details. It matches MC dockets only. For other docket types, search by USDOT number or company name.
Can I find a carrier's MC number from its DOT number?
Yes, when the carrier has an MC docket on file. Run a USDOT lookup, then open the FMCSA SAFER record from the result. SAFER lists the carrier's MC or other docket numbers.
Is this DOT number lookup free?
Yes. The AMZ Prep DOT number lookup is free and needs no signup. Search by USDOT number, MC number, or company name as often as needed. Data comes from official FMCSA records.
Where does the information come from?
Results come from FMCSA's public Company Census File on the U.S. DOT Open Data portal. Each search pulls the latest published record. The file refreshes daily and can lag recent carrier changes.
Does an active registration mean a carrier is safe to book?
No. Active USDOT registration is separate from operating authority, insurance, and out-of-service status. Use the FMCSA links in each result to check those before booking. Treat this lookup as the first step in carrier vetting.
What does "Not rated / not reported" mean?
The published record has no safety rating for this carrier. That is neutral, not a good or bad score. Most carriers are unrated. Open the SAFER link to review current safety data and inspection history.
Why can't I find a carrier?
Check the number for typos or try part of the legal company name. New registrations may not appear yet in the published data. For non-MC dockets, run a USDOT or company name search instead.
This tool displays published FMCSA registration data. It does not certify a carrier’s safety, insurance, or operating authority. Verify current information with FMCSA before arranging a shipment. View data source
