FMCSA Lookup
The government doesn't keep the carrier record in one place — it's spread across three separate federal systems that don't talk to each other. Here's what each one actually shows, why reading just one gets people burned, and how to pull the whole picture in a single search.

The three federal systems behind every carrier record
When somebody says "check them on FMCSA," they usually mean SAFER. But SAFER is only a third of the story. The full record lives in three systems, each answering a different question:
Who is registered?
The registration snapshot: legal name, DBA, physical address, entity type, USDOT status, fleet size, and the MCS-150 filing date. This is the identity layer — it tells you the company exists and what it told the government about itself.
What it misses: insurance detail, authority history, and any measure of how the carrier actually performs on the road.
May they operate — and who pays when it goes wrong?
The licensing system tracks the MC docket: which authority grants exist (property, passenger, household goods, broker, freight forwarder), whether each is active or revoked, plus every insurance and bond filing — the BMC-91 liability policies and the $75,000 BMC-84/85 broker instruments, with their full cancellation history.
What it misses: anything about safety. A carrier with spotless filings can still be a wreck on the road.
How do they actually drive?
Roadside inspection results, out-of-service rates, crash records, and the seven BASIC percentile categories. This is the ground-truth layer — generated by inspectors, not by the carrier. Our CSA score guide covers how to read the percentiles without over-trusting them.
What it misses: registration identity and insurance standing. A safe carrier can still have revoked authority.
Why reading one system gets people burned
Most freight-fraud losses trace back to somebody checking exactly one of the three systems and stopping. The classic failure patterns:
- SAFER-only check: the company exists and shows "Active" — but its insurance was cancelled last week (L&I) and its vehicle out-of-service rate is double the national average (SMS).
- Insurance-only check: the cert looks fine — but the entity quoting you only holds broker authority (L&I detail) and your load is about to be re-brokered.
- Safety-only check: clean inspections — on an authority that was revoked and re-registered under a new name at the same address, the classic chameleon carrier pattern that a single-system view can't see.
MC Look Up's whole reason to exist is doing that three-system join automatically: one search returns registration, authority grants with history, insurance filings, inspections, crashes, and a cross-reference screen — scored into a 0–100 number with an Approve / Review / Reject verdict. The scoring is documented end to end on our methodology page.
How to run the lookup
By USDOT number
The cleanest way. Take the number off the carrier packet or rate con and search it — the profile at /carrier/{DOT} merges all three systems. The full four-stage reading order is in our DOT number check workflow.
By MC number
Same profile, different key. MC search matters most when you're vetting a broker or confirming what a docket's authority grants actually permit — covered in the MC number guide.
By company name or location
Signed-in users can search by name. For browsing, the carrier directory ranks fleets by state and city with statewide registration stats rebuilt nightly.
What brokers should check before booking
The short version of the workflow, mapped to which system answers each question:
- Identity matches the paperwork (SAFER): legal name, address, phone, and email on the federal record line up with the party contacting you.
- Authority is active for this transaction (L&I): the specific grant — property carrier, broker, forwarder — that covers your load shows active, and the history isn't a revoke-reinstate carousel.
- Insurance is in force (L&I): active liability filing at the right level; recent cancellations are a reason to call the agent directly.
- Road performance is plausible (SMS): out-of-service rates near national averages, no crash pattern that changes your risk math.
- No reincarnation signals (cross-reference): shared phone, address, or officers with revoked carriers is the pattern our screening weights hardest.

Frequently asked questions
Is MC Look Up an official FMCSA website?
No. MC Look Up is an independent tool built on public FMCSA data. We pull from the same federal systems — registration, licensing, insurance, inspections, crashes — but the trust score and verdict are our own methodology, not an FMCSA rating.
Why isn't SAFER alone enough to vet a carrier?
SAFER shows one registration snapshot. It doesn't show insurance filing history, authority revocations and reinstatements, or safety measurement percentiles — those live in separate federal systems. A carrier can look clean on SAFER while its insurance is days from lapsing or its authority history is full of revocations.
How fresh is the data behind an FMCSA lookup here?
Authority and safety fields are re-checked when you run a lookup. The registration census archive is extended monthly, and statewide aggregates rebuild nightly. Insurance cancellations can lag in the federal system itself — the underwriter has to file first — so verify coverage directly with the agent on high-value loads.
Can I run an FMCSA lookup by company name instead of a number?
Yes — signed-in users can search by company name, and the carrier directory lets anyone browse by state and city. If you have a rate con or carrier packet, though, use the USDOT number on it: names get duplicated across thousands of similarly named companies, numbers don't.
