FMCSA carrier lookup

FMCSA maintains three primary public-facing tools that freight brokers use for carrier lookups: the SAFER Company Snapshot, the Licensing and Insurance (L&I) database, and the Safety Measurement System (SMS). Each surfaces different data from the same underlying FMCSA registry. Knowing which tool to use for which question — and what the most common reading mistakes are — is the difference between a superficial check and a real vetting signal.

For background on what FMCSA is and its regulatory mandate, see our overview: What is FMCSA?

Tool 1: FMCSA SAFER System

The SAFER System (Safety and Fitness Electronic Records) is the primary public interface for FMCSA carrier data. Access the Company Snapshot at safer.fmcsa.dot.gov/CompanySnapshot.aspx.

What SAFER surfaces

• Entity type and operating status: Whether the USDOT number is Active, Inactive, or Out of Service.
• Legal name and DBA: The registered entity name. Cross-check against what the carrier stated in their email.
• Physical address and mailing address.
• Power units and drivers: The number of trucks and drivers registered under this carrier. A carrier claiming to have 200 trucks but showing 3 power units on FMCSA is misrepresenting capacity.
• Safety rating: Satisfactory, Conditional, Unsatisfactory, or Not Rated.
• Carrier operation type: Interstate, intrastate hazmat, intrastate non-hazmat.
• Insurance on file: Whether BIPD and cargo coverage is filed with FMCSA.
• Inspection and crash summary: 24-month totals for inspections, driver OOS violations, vehicle OOS violations, and crashes (fatal, injury, tow-away).

How to read the inspection data correctly

The most common mistake brokers make reading SAFER is looking at inspection and OOS numbers in isolation. The relevant signal is theratio of OOS violations to total inspections. A carrier with 50 inspections and 10 driver OOS violations (20% OOS rate) is more concerning than a carrier with 5 OOS violations out of 200 inspections (2.5% OOS rate). The national average driver OOS rate is approximately 5% and vehicle OOS rate is approximately 20% — carriers significantly above these averages warrant closer review.

Crash data in SAFER shows counts only — it does not reflect fault determination. FMCSA tracks crashes regardless of whether the carrier was at fault. A high crash count in a 24-month period with a large fleet may still represent a below-average crash rate per mile. Size context matters.

Tool 2: FMCSA Safety Measurement System (SMS)

The Safety Measurement System calculates and displays BASIC (Behavior Analysis and Safety Improvement Category) scores — the most detailed safety data publicly available on any carrier.

The seven BASIC categories

• Unsafe Driving: Speeding, reckless driving, improper lane changes. Investigation threshold: 65%.
• Hours-of-Service (HOS) Compliance: Logbook violations, fatigued driving. Investigation threshold: 65%.
• Driver Fitness: CDL violations, driver qualification file issues. Investigation threshold: 80%.
• Controlled Substances/Alcohol: Drug and alcohol violations. Investigation threshold: 80%.
• Vehicle Maintenance: Brake violations, lights, tires, cargo securement. Investigation threshold: 80%.
• Hazardous Materials Compliance: Applies only to carriers hauling hazmat. Investigation threshold: 80%.
• Crash Indicator: Crash frequency relative to peer carriers. Investigation threshold: 65% (large carriers) / 75% (smaller carriers).

How to read BASIC percentile scores

A BASIC percentile score of 70 means the carrier performs worse than 70% of comparable carriers in that category. It is a relative ranking within a peer group of carriers with similar operation type, size, and inspection exposure — not an absolute score. A carrier in the top 35% (score below 65%) is within normal range for most brokers' booking thresholds.

Important caveats on BASIC scores:

• Carriers with fewer than 3 inspections in the 24-month window will not have scores in most BASICs. No score does not mean safe — it means insufficient data.
• Some BASIC data is not publicly visible. Following the FAST Act of 2015, FMCSA restricted public access to the Hazardous Materials and Driver Fitness BASIC data for general-public viewing, though it remains available to enforcement and certain registered users.
• BASIC scores are not safety ratings. Only a formal compliance review results in a Satisfactory/Conditional/Unsatisfactory rating. High BASIC scores indicate risk but do not constitute an official enforcement finding.

Tool 3: FMCSA Licensing and Insurance (L&I) database

The L&I database is the primary source for operating authority status and insurance filings. While SAFER surfaces this data in a combined snapshot, the L&I database shows the complete insurance filing history and is the authoritative record for authority status.

For the full step-by-step walkthrough of using the L&I database to verify MC authority status, insurance, and BOC-3 filings, see our dedicated guide: MC number lookup.

Tool 4: QCMobile

QCMobile is FMCSA's official iOS and Android app. It provides the same SAFER data in a mobile interface with a cleaner layout than the SAFER website. Enforcement officers use it for roadside checks; brokers can use it for desk lookups when working from a tablet or when the SAFER website is slow.

QCMobile also supports scanning carrier cab cards via camera to auto-populate the USDOT number field — a faster entry method than manual typing. For a full USDOT-specific verification walkthrough, see DOT number verification.

Common mistakes brokers make reading FMCSA data

Mistake 1: Treating "Not Rated" as a positive signal

The majority of carriers have never had a formal compliance review and will show "Not Rated" for their safety rating. This is the default state, not an endorsement. New carriers with fresh MC authority and no inspection history are also Not Rated. Always check BASIC scores and authority age alongside the safety rating field.

Mistake 2: Not checking the MCS-150 filing date

FMCSA requires carriers to update their MCS-150 (Motor Carrier Identification Report) every two years. A carrier whose last MCS-150 filing was three or four years ago may be operating on a technically lapsed registration. The SAFER snapshot shows the MCS-150 date — check it.

Mistake 3: Accepting fleet size numbers without scrutiny

The power units (trucks) and drivers counts in SAFER come from the carrier's self-reported MCS-150 filings. They are not verified by FMCSA in real time. A carrier claiming in an email to have 50 trucks but showing 2 power units on their SAFER record has either misrepresented their capacity or not updated their MCS-150 recently. Either is a yellow flag.

Mistake 4: Not comparing the SAFER address to the carrier email

Fraud schemes frequently involve carriers sending email from a domain or address that does not match the FMCSA registration. Always compare the physical address, phone number, and company name in the SAFER snapshot against what appears in the carrier's email signature. Discrepancies are a primary indicator of identity theft or impersonation. See the anatomy of a fraudulent carrier email for detailed fraud patterns.

Mistake 5: Missing the chameleon carrier signal

A carrier with a clean, new USDOT record may be a reincorporated entity shedding a prior safety history. Cross-reference the carrier's physical address and principal names against other FMCSA registrations using the company name search in SAFER. If another carrier at the same address or with the same principals has a poor safety record and is now inactive or revoked, you may be looking at a chameleon carrier. See our full guide: what is a chameleon carrier.

The 60-second carrier vetting flow

For a broker receiving 30–50 carrier emails per posted load, the goal is a verified first-pass triage that surfaces disqualifying signals immediately and flags marginal cases for secondary review. Here is the 60-second minimum:

• Open SAFER Company Snapshot and enter the MC or USDOT number from the email.
• Check Operating Status: Active or stop.
• Compare company name and address to the email signature.
• Check Safety Rating: anything other than Satisfactory or Not Rated requires additional scrutiny.
• Note authority grant date: flag if under 6 months.
• Check insurance: confirmed on file.
• Note power units vs. what the carrier claims: flag major discrepancy.
• If time permits, open SMS and check available BASIC scores.

Automating FMCSA lookups with Keelway

The 60-second manual flow works for occasional new-carrier checks but does not scale to the volume of emails a busy brokerage receives. A broker running 15 active loads simultaneously — each with 30+ carrier emails — cannot run SAFER lookups manually for every contact. Keelway's carrier email automation runs FMCSA lookups on every inbound email automatically, computes a carrier trust score that combines FMCSA data with additional signals, and surfaces a ranked carrier list with trust scores already computed.

Brokers using Keelway see each carrier's rate, trust score, and authority status in a single row — and make booking decisions without opening a browser tab. At $799/mo flat, it costs less than the time value of three manual lookups. Book a demo to run it on your existing Gmail inbox.
