O TruckingDOT Number Lookup: How to Search FMCSA SAFER (Step-by-Step)
What Is the FMCSA SAFER System?
The FMCSA SAFER system (Safety and Fitness Electronic Records) is the federal government's free, public database that tracks every registered motor carrier, broker, and freight forwarder in the United States. Maintained by the Federal Motor Carrier Safety Administration, it contains operating authority data, safety records, insurance filings, inspection history, and company registration details for every entity that holds a USDOT number.
SAFER is not a paid subscription service. There is no login required, no monthly fee, and no limit on how many searches you can run. It is available 24 hours a day, 7 days a week, and anyone can use it. Brokers use SAFER to verify carriers before tendering loads. Shippers use it to check broker authority. Carriers use it to verify their own status and look up potential partners. Dispatchers use it as the first step in every vetting process.
Free and Public
No account, no subscription, no fees. SAFER is funded by taxpayers and maintained by FMCSA as a public safety resource. Every search is free and instant.
Every Registered Carrier
If a carrier, broker, or freight forwarder has a USDOT number, they're in SAFER. This includes active, inactive, and out-of-service entities.
Official Government Data
SAFER data comes directly from FMCSA filings. Authority status, insurance filings, and registration details are updated in near real-time as changes are processed.
Used by Everyone
Brokers, shippers, carriers, dispatchers, insurance companies, freight factoring companies, and law enforcement all rely on SAFER for carrier verification.

How to Search for a DOT Number: Step-by-Step
Searching SAFER takes less than 60 seconds once you know the process. You can search by USDOT number, MC/MX/FF number, or company name. Searching by DOT number is the most reliable method since company names can have slight variations.
Step-by-Step Search Process
- 1
Go to SAFER
Navigate to safer.fmcsa.dot.gov in any web browser. No login or account is required.
- 2
Click "Company Snapshot"
On the main SAFER page, click the "Company Snapshot" link. This is the primary search tool for looking up individual carriers and brokers.
- 3
Enter Your Search Criteria
Choose your search method: USDOT Number, MC/MX Number, or Company Name. Enter the value and click "Search." If searching by name, use the legal name (not a DBA) for best results.
- 4
Review the Company Snapshot
The results page displays the carrier's complete profile in one view. You'll see registration details, operating status, authority information, safety data, and insurance status all on a single page.
- 5
Drill Into Details
Click links within the snapshot for deeper data: inspection reports, crash details, safety ratings, and operating authority history. Each section links to more granular FMCSA records.
Search by DOT Number, Not Name
How to Read SAFER Company Snapshot Results
The Company Snapshot page packs a lot of information into one screen. Here's what every field means and why it matters. Understanding these fields lets you evaluate any carrier or broker in under two minutes.
Company Identification Fields
Entity Type
Shows whether the entity is a Carrier, Broker, Freight Forwarder, or a combination. A company can hold multiple types simultaneously (e.g., Carrier and Broker).
Legal Name
The official registered business name on file with FMCSA. This is the name on their incorporation or LLC documents, not necessarily what they market under.
DBA Name (Doing Business As)
The trade name or brand name the company operates under publicly. Compare this with the name on the rate confirmation to verify you are dealing with the actual registered entity.
Physical Address
The actual business location on file. A P.O. Box here is a potential red flag. Compare this with what the broker or carrier gave you to spot potential identity fraud.
Phone Number
The registered phone number. Always call this number to verify the person you are dealing with actually works there. This is one of the most effective ways to catch double-brokering scams.
Mailing Address
Where FMCSA sends official correspondence. This can differ from the physical address and is less useful for verification purposes.
Registration and Numbers
USDOT Number
The unique federal identification number assigned to the entity. Required for all interstate carriers operating vehicles over 10,001 lbs GVWR or transporting hazardous materials.
MC/MX/FF Numbers
MC (Motor Carrier), MX (Mexico-domiciled), or FF (Freight Forwarder) operating authority numbers. The MC number is separate from the DOT number and specifically authorizes for-hire freight transportation.
State Carrier ID
The state-level registration number, if applicable. Some states require separate registration in addition to the federal USDOT number.
DUNS Number
The Dun & Bradstreet business identification number. Not all carriers have one listed, but it can be useful for cross-referencing business credit data.
MCS-150 Form Date
The date the carrier last updated their biennial registration. If this date is more than two years old, the carrier is out of compliance with FMCSA. An outdated MCS-150 is a red flag that the carrier may not be actively managing their authority.
Operations and Equipment
Operating Status
Shows whether the entity is currently AUTHORIZED to operate. This is the single most important field on the entire page. If it does not say 'AUTHORIZED' (for brokers) or 'ACTIVE' (for carriers), stop right there.
Out-of-Service Date
If populated, this shows when the entity was placed out of service. An entity with an OOS date cannot legally operate and should not be hauling or brokering freight.
Power Units
The number of trucks the carrier operates. This gives you a sense of fleet size. A carrier claiming to be a large fleet but showing 2 power units is a discrepancy worth investigating.
Drivers
The number of drivers employed. Compare this to power units for a sanity check. A carrier with 50 trucks and 3 drivers does not add up.
Operation Classification
Shows whether the carrier operates as Authorized For Hire, Exempt For Hire, Private (Property), Private (Passengers), or other classifications.
Carrier Operation
Indicates Interstate, Intrastate HM (Hazardous Materials), or Intrastate Non-HM. Interstate carriers are federally regulated; intrastate carriers may have different requirements.
Cargo Carried
Lists the types of freight the carrier is registered to haul: General Freight, Household Goods, Metal/Sheets/Coils, Motor Vehicles, Refrigerated Food, and others.
HM Carrier (Hazardous Materials)
Indicates whether the carrier is registered to transport hazardous materials. HM carriers have additional inspection requirements and safety compliance obligations.
Watch for Mismatches
Reading Safety and Inspection Data
Below the registration section, the Company Snapshot displays safety and inspection data. This section summarizes the carrier's roadside inspection results, vehicle and driver out-of-service rates, and reported crashes. Understanding these numbers helps you assess whether a carrier takes safety seriously.
Key Safety Metrics Explained
Inspections
The total number of roadside inspections the carrier has undergone in the past 24 months. SAFER breaks these down by vehicle inspections, driver inspections, and hazmat inspections. More inspections generally indicate higher road activity. A carrier with zero inspections in two years either runs very little or is very new.
Out-of-Service (OOS) Rates
This is the percentage of inspections where the vehicle or driver was placed out of service for safety violations. The national average vehicle OOS rate is approximately 21%. The national average driver OOS rate is approximately 6%. Carriers significantly above these averages have maintenance or compliance problems.
Crash Reports
The number of DOT-reportable crashes involving the carrier's vehicles in the past 24 months. A DOT-reportable crash involves a fatality, an injury requiring transport to a medical facility, or a vehicle towed from the scene. Not all crashes are the carrier's fault, but a high count relative to fleet size warrants concern.
Violations
Violations found during inspections are categorized by type: vehicle maintenance, driver fitness, hours of service, controlled substances, and hazardous materials. Repeated violations in the same category indicate a systemic problem, not a one-time mistake.
Red Flags in Safety Data
SAFER Data Lags Behind
Checking Insurance Status on SAFER
The insurance section of the Company Snapshot shows whether a carrier has valid insurance filings on record with FMCSA. This does not display the actual insurance policy details, but it does confirm whether the required filings have been made and are currently active.
Insurance Filing Types
BMC-91X (Liability Insurance)
This filing proves the carrier's insurance company has filed proof of financial responsibility with FMCSA. For-hire carriers are required to maintain minimum coverage of $750,000 for general freight (higher for hazmat and passenger carriers). If the BMC-91X shows as "Active," the carrier has current liability insurance on file.
BMC-34 (Cargo Insurance)
Filed by household goods carriers to prove cargo insurance coverage. Not required for all carrier types, but if it appears, it means cargo insurance is on file.
BMC-84 / BMC-85 (Broker Bond)
For brokers, the BMC-84 is a surety bond and the BMC-85 is a trust fund agreement. Brokers must have one of these on file for a minimum of $75,000 to maintain their authority. If neither shows as active for a broker, they cannot legally broker freight.
Good Signs
- BMC-91X showing 'Active' status
- Insurance filed recently (within 12 months)
- Coverage meets or exceeds FMCSA minimums
- Broker has active BMC-84 or BMC-85
Warning Signs
- No insurance filings on record
- BMC-91X showing 'Inactive' or no status
- Broker with no BMC-84 or BMC-85 on file
- Insurance cancellation pending
SAFER Insurance Data Is Not Real-Time
Other DOT Lookup Tools
FMCSA SAFER is the definitive source for authority and registration data, but it does not cover everything. Several third-party tools complement SAFER with credit scores, payment history, and carrier reviews. Here's a brief comparison of the most widely used options.
Carrier411
$34.95/monthIndustry-standard platform for broker and carrier credit checks. Provides credit scores, days-to-pay data, carrier-submitted complaint reports, and authority verification. Has mobile apps for iOS and Android. The largest database of carrier-submitted broker payment reports in the industry. We wrote a detailed Carrier411 vs FMCSA SAFER comparison if you want a deeper breakdown.
FMCSA SMS (Safety Measurement System)
FreeThe FMCSA SMS system provides detailed safety performance data beyond what SAFER shows. Includes CSA scores across seven BASICs categories (Unsafe Driving, Crash Indicator, HOS Compliance, Vehicle Maintenance, Controlled Substances, Hazmat Compliance, Driver Fitness), along with inspection details and trend data. Free and publicly accessible.
Highway
VariesA newer carrier monitoring platform used primarily by brokers and shippers to verify carriers in real time. Integrates FMCSA data with insurance monitoring, identity verification, and compliance alerts. Gaining traction in the industry as a fraud prevention tool, especially for detecting double-brokering and identity theft.
Truckstop
With subscriptionTruckstop's load board includes integrated carrier and broker verification. Credit ratings, payment performance, and authority status are accessible directly from load search results. Convenient if you are already a Truckstop subscriber, but not as deep as dedicated verification tools.
No Single Tool Does Everything
How Dispatchers Use DOT Lookups
At O Trucking, we check SAFER before every partnership, whether we are vetting a new broker for one of our carriers or verifying a carrier's credentials for a shipper. DOT lookups are not a one-time task. We run them regularly because authority status, insurance, and safety data can change at any time.
What Our Dispatch Team Checks on Every SAFER Lookup
Active Operating Status
Authority must show 'Active' or 'Authorized' — no exceptions. If it says anything else, we do not proceed.
Insurance Filed and Current
BMC-91X must be active for carriers. BMC-84 or BMC-85 must be on file for brokers. We verify, then request a current COI.
Low Out-of-Service Rates
We look for vehicle OOS rates under 25% and driver OOS rates under 8%. Above these thresholds, we investigate further before partnering.
Clean Inspection History
Repeated violations in the same category — especially hours of service or vehicle maintenance — indicate systemic issues we avoid.
Recent MCS-150 Update
If the MCS-150 date is more than 24 months old, the carrier is not maintaining compliance. This is a basic requirement that responsible carriers keep current.
Phone and Address Verification
We call the phone number listed on SAFER, not the number provided by the contact. This is how we catch double-brokering and identity fraud attempts.
This process takes about two minutes per entity. We run it on every new broker and every new carrier, and we re-check existing partners quarterly. Combined with our full broker verification process that includes credit checks on Carrier411 and factoring company payment data, this SAFER lookup is the foundation of how we protect our carriers from fraud, non-payment, and unsafe operations.

DOT Number Lookup FAQ
Common questions about searching the FMCSA SAFER database and using DOT number lookups.
How do I look up a carrier's DOT number?
Go to safer.fmcsa.dot.gov, click 'Company Snapshot', and search by DOT number, MC number, or company name. Results are instant and free. You do not need an account or login to use SAFER.
What information can I see on a SAFER lookup?
Company name, address, DOT/MC numbers, operating status, authority status, insurance status, number of trucks/drivers, safety data, inspection results, crash history, and last MCS-150 update date. All of this information is publicly available at no cost.
Can I look up my own DOT status?
Yes, search your own DOT number on SAFER to verify your authority shows 'Active' and insurance is filed correctly. Do this monthly to catch any issues before brokers or shippers see them. An outdated MCS-150 or lapsed insurance filing can cost you loads.
Is DOT number lookup information public?
Yes, all FMCSA SAFER data is public record. Anyone — brokers, shippers, carriers, the general public — can search any carrier's information for free. There is no registration required and no limit on how many searches you can run.
We Verify Every Carrier and Broker
Our dispatch team checks SAFER before every load — authority status, insurance filings, safety data, and inspection history. We run this verification so you can focus on driving, not researching.
