How to verify a carrier — the complete broker checklist
Before you tender a load to a new carrier, you need to confirm five things: operating authority is active, insurance is in force, the safety profile is acceptable, the equipment exists, and the identity matches the public carrier record. This guide walks each step in the same order an experienced freight broker runs them.
Quick Answer
To verify a carrier, run five checks in this order: (1) confirm operating authority is active in the public registry, (2) confirm liability and cargo insurance are on file and current, (3) review the safety score and out-of-service rates, (4) inspect the equipment footprint against the load type, and (5) match the identity (legal name, DBA, address, phone) against what the carrier told you. Skip any one of these and you are guessing.
- Authority status: active, not revoked or out-of-service
- Insurance: liability and cargo both current today
- Safety: BASIC scores, out-of-service rate, recent crashes
- Equipment: power units and trailers actually observed
- Identity: legal name, DBA, address, phone match the contact
Why verification matters in 2026
Cargo theft and double-broker fraud reached new highs in 2024 and have stayed elevated. Industry trade groups estimate strategic cargo theft — schemes where a bad actor poses as a legitimate carrier — accounts for hundreds of millions in losses annually. Many of those losses trace back to a single skipped step in the vetting workflow.
Verification is not just about fraud. A carrier with lapsed insurance can leave you holding the bag on a damage claim. A carrier with conditional safety scores raises your shipper's risk profile. A carrier without the right equipment for the load is a missed pickup waiting to happen. The checklist below catches all four classes of problem.
The public record alone is not enough
A free public lookup will tell you whether a carrier's authority is active. It will not tell you whether the MC number was hijacked last week, whether the carrier was dormant for two years before reactivating, or whether the contact information you received matches their registered filing. The full vetting workflow joins the public record with rules-based fraud detection.
Step 2: Confirm current insurance — same day
Insurance status moves. A carrier whose policy was active last week may have lapsed by the time the truck shows up. The only reliable verification is to read the carrier's most recent insurance filings on the day of tender — not when you onboarded, not yesterday, today.
The public record returns two relevant policies: liability (BIPD: Bodily Injury / Property Damage) and Cargo. Confirm both have an effective date in the past and a cancellation date either blank or in the future. If you see a cancellation date that has already passed with no superseding filing, the coverage is lapsed.
- Liability minimum is $750,000 for general freight (higher for hazmat).
- Cargo minimum varies by load — most shippers want $100,000 minimum, many require more.
- If you require a Certificate of Insurance (COI), ask for it directly from the broker, not the carrier — and call the agency on the COI to confirm it is real (acord-fraud is rampant).
Step 3: Review safety profile
The federal CSA (Compliance, Safety, Accountability) program publishes Behavior Analysis and Safety Improvement Categories (BASIC) scores. Each measures the carrier's relative performance vs. peers on a percentile basis. Scores above the intervention threshold for any BASIC trigger heightened regulatory scrutiny and signal elevated risk.
- Unsafe Driving — speeding, reckless driving, improper lane change. Threshold: 65th percentile (passenger), 80th (general).
- Hours-of-Service Compliance — log violations, off-duty driving. Same thresholds.
- Driver Fitness — CDL violations, medical-card failures.
- Controlled Substances/Alcohol — failed tests, refusals.
- Vehicle Maintenance — out-of-service violations, brake/light/tire issues.
- Hazmat Compliance — placarding, paperwork.
- Crash Indicator — historical crash involvement (not public).
Pull the carrier's roadside inspection history. A pattern of recent out-of-service violations is a stronger signal than the rolled-up BASIC score, because BASIC is lagging and inspections refresh in near real-time.
Step 4: Match equipment to the load
A carrier authorized to haul general freight may not own a single reefer. Cargo-classification fields on the public record are self-reported — what the carrier is allowed to haul, not what they actually run. The reliable signal is roadside inspection data: every inspection records the power unit and trailer VINs, which you can VIN-decode for equipment type.
Carrier Check's equipment card on each carrier page is built from this inspection-driven inference. If a carrier claims they run dry vans but every inspection in the last 12 months was on a reefer, ask why. The opposite mismatch (claims reefers, runs dry vans) is a classic fraud setup — they have no intent to deliver the actual load.
Step 5: Match identity end-to-end
The last step closes the loop. The carrier sales rep you are talking to should match the public carrier record on legal name, DBA, physical address, and phone. Independent verification is the rule, not the exception.
- Call the phone number on the public carrier record — not the number on the rate confirmation. Bad actors spoof rate-confirm numbers.
- Email from a domain that matches the carrier's DBA, not a free webmail address. Free webmail + new MC is a high-risk combination.
- Physical address should be a commercial yard or office — not a residential address or UPS Store mailbox.
- DBA on the carrier packet should match the public record exactly. Even slight reorderings (Acme Trucking LLC vs Acme Trucking Inc) deserve a follow-up question.
Use the tool, not just the checklist
Running these five checks manually on every carrier takes 10-15 minutes. The Carrier Check tool runs all five in parallel — verified authority, current insurance, observed inspections, and our internal fraud-signal rules engine — in under a second. Free for the first 100 lookups per day.
Pro Tips
- Recheck insurance the day of tender. Onboarding-time insurance verification is necessary but not sufficient. Policies lapse mid-month. Build a same-day recheck into your tender workflow.
- Phone calls beat email for new carriers. A short voice conversation with the carrier's dispatcher catches identity-flip scams that an email exchange will not. The bad actor's voice + accent rarely matches the carrier's region of registration.
- Score the lane, not just the carrier. A carrier with a clean safety record but no recent inspections in the destination state may not actually run that lane. Match equipment footprint and lane history before tendering.
- Document your vetting steps. Insurance carriers (yours, not the trucking company's) increasingly ask for the vetting workflow during claim disputes. A timestamped log of authority + insurance + safety + identity checks at tender protects you when something goes wrong.
Frequently Asked Questions
How long should carrier vetting take?
Manual vetting across public carrier lookups, insurance filings, and safety dashboards typically takes 10-15 minutes per carrier. Using an integrated tool like Carrier Check brings that to under a minute by pulling all five signals in parallel.
Is a Carrier411 / RMIS / MyCarrierPackets check enough?
Those tools surface public carrier data plus self-reported carrier documents. They are useful but typically lag a day or two on insurance status, do not run identity-flip fraud detection, and charge per query. They do not replace a same-day insurance verification.
What is the difference between active and registered?
A carrier can be "registered" (USDOT number issued) without having active operating authority. Many intrastate carriers and private carriers fall into this bucket and cannot legally haul interstate. Always confirm "authority status: active" specifically, not just that the DOT number exists.
What do I do if a carrier flunks one of the five checks?
Do not tender. There is almost always another carrier on the lane. The five-step checklist is a gating function, not a scoring rubric — a single hard fail (revoked authority, lapsed insurance, address mismatch, equipment-type mismatch on the load) is grounds to reject the carrier outright. Soft signals (one out-of-service violation in the past year, BASIC at the 67th percentile when threshold is 80th) are judgement calls.
Can a broker be liable if a vetted carrier causes a crash?
Brokers face increasing negligent-selection lawsuits when carriers they vetted cause crashes. A documented, repeatable vetting workflow is the broker's best defense. Industry guidance is to verify authority and insurance every time, retain the vetting record for the duration of the load plus statute-of-limitations, and avoid using carriers with at-the-threshold BASIC scores or recent out-of-service violations.
How often do MC numbers change hands?
Officially, MC numbers are not transferable — they are tied to the legal entity that filed for authority. In practice, dormant carriers can have their authority reactivated by new owners through ownership-change filings. Our rules engine flags this pattern (long dormancy + recent reactivation + new contact info) as a high-risk signal.
