Carrier identity
What should I know about how to identify the trucking company and US DOT number?
Find the carrier behind a commercial truck using the door markings, crash report and free FMCSA SAFER record, without treating public data as fault.
Quick answer
Start with the US DOT number painted on the power unit, the company name, plate, trailer markings and crash report. Enter the DOT number in FMCSA's free SAFER Company Snapshot to see the carrier name and public federal record. The tractor, trailer, driver and cargo may connect to different companies, so save every marking. A SAFER record identifies a carrier but does not decide fault.

01
Collect every company identifier
Photograph both cab doors, the rear of the trailer, license plates and any unit or trailer number. The crash report may list a carrier, owner, driver and insurance entry. A leased tractor can pull another company's trailer, and a driver can work through a contractor. Keeping each identifier prevents one logo from being treated as the whole ownership picture.
- US DOT and MC numbers
- Legal name, DBA name, logo and unit number
- Tractor plate, trailer plate and trailer number

Read a SAFER snapshot without grading it
SAFER can show identification, fleet size, commodities, inspection summaries, crash information and a safety rating if one is on file. A missing value is not zero. A crash count is not a finding that a carrier caused those crashes. Use the snapshot to identify records and companies, then preserve the date you looked because public data can update.
- Save a PDF or screenshot with the lookup date
- Keep the legal and DBA names exactly as shown
- Do not label a missing rating as a good or bad rating

Questions
Short answers that stand on their own
Where is the US DOT number?
It is commonly displayed on the side of the commercial power unit. It may also appear in the crash report.
Does a SAFER crash count prove fault?
No. It is public carrier data for a reporting period and does not decide responsibility for any crash.
A quick reality check
What this page can and cannot tell you
This page cannot decide how the crash happened, who was at fault, whether a carrier controlled the trip, whether a particular record exists, insurance coverage, case value or a legal deadline. Public carrier data and vehicle categories are starting points for finding records; they do not establish responsibility or legal eligibility. A licensed attorney must review the complete facts and current law.
When you are ready
You do not need every record to start
