To look up a DOT number, use the Federal Motor Carrier Safety Administration’s free Company Snapshot tool at safer.fmcsa.dot.gov. You can search by company name, USDOT number, or MC/MX number, and the result shows the carrier’s safety record, operating status, insurance, and more. If the truck is right in front of you, the USDOT number is required by federal law to appear on both sides of every commercial motor vehicle.1eCFR. 49 CFR Part 390 – Section 390.21 Marking of Self-Propelled CMVs and Intermodal Equipment
Using the SAFER Company Snapshot
The Company Snapshot lives inside FMCSA’s Safety and Fitness Electronic Records (SAFER) system. It’s free, needs no account, and takes about a minute.2Federal Motor Carrier Safety Administration. Company Snapshot
- Go to safer.fmcsa.dot.gov.3Federal Motor Carrier Safety Administration. SAFER Home
- Under “FMCSA Searches,” click “Company Snapshot.”
- Pick a search method: USDOT number, MC/MX number, or company name.
- Enter what you have and click “Search.”
Searching by company name is the usual path when you don’t already have the number. Common business names can return several results, so match the physical address and state to confirm you have the right carrier. You may also see FF numbers (freight forwarders) or MX numbers (certain Mexico-domiciled carriers) in results.4Federal Motor Carrier Safety Administration (FMCSA). What Is Operating Authority (MC Number) and Who Needs It?
For more detail on operating authority than the Snapshot shows, use FMCSA’s Licensing and Insurance (L&I) database. It lists pending applications, a history of authority changes, and any pending insurance cancellations, searchable by MC or USDOT number.5Federal Motor Carrier Safety Administration (FMCSA). How Can I Check the Status of My Operating Authority
Reading the Number Off a Vehicle
Federal regulations require every commercial motor vehicle to display its USDOT number, preceded by the letters “USDOT,” on both sides of the vehicle. The lettering must contrast with the background and be legible from 50 feet away in daylight.1eCFR. 49 CFR Part 390 – Section 390.21 Marking of Self-Propelled CMVs and Intermodal Equipment The regulation doesn’t dictate an exact spot beyond “both sides,” but the cab doors are the usual location. Once you have the number, plug it into SAFER.
What the Company Snapshot Shows You
Once you land on a carrier’s page, you’re looking at a public safety profile.2Federal Motor Carrier Safety Administration. Company Snapshot
Identification and Size
The top of the page shows the legal name, physical address, phone number, and whether the USDOT number is active or inactive. Entity type tells you whether the company is a carrier, broker, freight forwarder, or a combination. Reported power units and driver counts give a rough sense of the operation’s size.6Federal Motor Carrier Safety Administration. Company Snapshot DOT INC – SAFER Web
Safety Record
If the carrier has been formally rated, you’ll see Satisfactory, Conditional, or Unsatisfactory. Many smaller carriers have never been rated at all. Below that sits a 24-month summary of roadside inspections, broken into vehicle, driver, and hazmat categories with out-of-service percentages, plus crash counts by fatal, injury, and tow-away incidents over the same window.6Federal Motor Carrier Safety Administration. Company Snapshot DOT INC – SAFER Web Crash counts reflect involvement, not fault.
Authority and Insurance
The Snapshot also indicates whether the carrier runs interstate, intrastate, or both, lists the cargo types it’s authorized to haul, and links to insurance details showing active coverage and any pending cancellations. A carrier flagged “NOT AUTHORIZED” isn’t automatically illegitimate; private carriers hauling their own goods and intrastate-only operators can run without for-hire authority.6Federal Motor Carrier Safety Administration.

Going Deeper With the Safety Measurement System
The Snapshot summarizes; FMCSA’s Safety Measurement System at ai.fmcsa.dot.gov/SMS breaks a carrier’s record into seven categories called BASICs:7Federal Motor Carrier Safety Administration (FMCSA). Safety Measurement System (SMS) Methodology
- Unsafe Driving (speeding, reckless driving, distracted driving)
- Crash Indicator (patterns based on crash history)
- Hours-of-Service Compliance (driver fatigue rules)
- Vehicle Maintenance (brakes, lights, other mechanical issues)
- Controlled Substances and Alcohol
- Hazardous Materials Compliance
- Driver Fitness (licensing, medical certificates, qualifications)
All BASIC data is publicly visible for passenger carriers. For property carriers, inspection and investigation data is public, but the Crash Indicator and Hazardous Materials Compliance categories are hidden from public view.8Federal Motor Carrier Safety Administration. Safety Measurement System A carrier with clean crash numbers but a high out-of-service rate for vehicle maintenance is worth a second look.
Looking Up a Moving Company
Hiring a household goods mover is one of the most common reasons to run a DOT lookup, and it’s also where consumer fraud is most common. FMCSA runs a dedicated Protect Your Move page at fmcsa.dot.gov/protect-your-move, plus a household goods search tool at ai.fmcsa.dot.gov/hhg/search.asp that lets you check whether a specific company is registered as a carrier or a broker for interstate moves.9Federal Motor Carrier Safety Administration (FMCSA). Protect Your Move10Federal Motor Carrier Safety Administration. Search by Company – Mover Registration Search
Pay close attention to entity type on the Snapshot. A company registered only as a broker isn’t the one physically moving your belongings; brokers arrange transportation and hire other carriers to do the work, which can complicate things if something goes wrong. A legitimate interstate mover will have active operating authority and active insurance. If either is missing, look elsewhere.
Why the Number Might Show as Inactive
When a lookup returns an inactive USDOT status, the most common cause is a missed biennial update. Every carrier must file an updated MCS-150 with FMCSA every two years, on a schedule set by the last two digits of the USDOT number.11Federal Motor Carrier Safety Administration (FMCSA). When Am I Required to File a Biennial Update? FMCSA can deactivate the number for a missed filing, and the carrier faces civil penalties of up to $10,243 in total.12Federal Motor Carrier Safety Administration (FMCSA). What Are the Penalties for Failure to Submit My Biennial Update An inactive status isn’t proof of anything shady on its own. It’s a paperwork flag. If you’re about to hire the carrier, ask about it before you sign.
Filing a Complaint After a Lookup
If a lookup surfaces problems, or you’ve already had a bad experience with a carrier, file a complaint through the National Consumer Complaint Database at nccdb.fmcsa.dot.gov. You select the complaint type (moving company, truck company, bus company, or property broker), identify the company by name or DOT number, and describe what happened with dates, locations, and any photos or documents you can upload.13Federal Motor Carrier Safety Administration (FMCSA). How to File a Complaint FMCSA reviews the complaint and notifies you whether it’s actionable; leaving an email address speeds that up.
