FMCSA Carrier Lookup Guide
How to look up a trucking carrier on the FMCSA SAFER website before you broker a load to them, what each field actually means, and the red flags that should make you walk away. Written for the broker / dispatcher running due diligence on a new carrier.
What FMCSA SAFER is
The Federal Motor Carrier Safety Administration (FMCSA) is the federal agency overseeing commercial motor carrier safety. Every interstate trucking company must register with FMCSA and gets two identifiers: a USDOT number (federal identifier) and an MC number (operating authority number). FMCSA publishes safety, insurance, inspection, and operating authority data on every carrier through the SAFER (Safety and Fitness Electronic Records) public database.
SAFER is the canonical "first call" before brokering a load. If the carrier isn't in SAFER, isn't authorized, isn't insured, or has a bad safety record, you shouldn't be sending them your customer's freight.
How to run a SAFER lookup
Two paths — both free, both authoritative:
- SAFER Company Snapshot — safer.fmcsa.dot.gov/CompanySnapshot.aspx. Enter USDOT# or MC#. Returns: operating authority, insurance on file, equipment count, basic safety summary, crash record.
- FMCSA SMS (Safety Measurement System) — ai.fmcsa.dot.gov/SMS/. Same carrier, more detailed safety metrics broken out by BASIC category (Unsafe Driving, Hours of Service, Driver Fitness, Vehicle Maintenance, etc.). Use this for a deeper look once SAFER raises a flag.
What every field on SAFER means
| Field | What it means |
|---|---|
| USDOT Number | The federal identifier. Permanent. Used for everything FMCSA-related. |
| MC/MX Number | The operating authority number. Required for interstate for-hire common/contract carriers and brokers. Intrastate carriers and private carriers may not have one. |
| Operating Authority Status | "Active" = currently authorized to operate. "Inactive" = revoked or surrendered. "Out of Service" = federal OOS order. |
| Operating Status | Authorized For Hire / Authorized Private / Authorized for Property / Out of Service. The carrier's currently-allowed operation type. |
| Insurance on File | BMC-91 (cargo) and BIPD (liability) forms. Should show coverage amounts. Minimum federal: $750K liability for non-hazmat, $5M for hazmat, $5,000 cargo (often higher contractually). |
| BMC-32 / BMC-91 | Cargo insurance certificate forms. BMC-91X = the binder for liability. |
| Power Units | Self-reported number of tractors / trucks. Bias: carriers self-report, so this is approximate. Cross-check against the company's actual operation. |
| Drivers | Self-reported driver count. Same caveat. |
| Safety Rating | One of: Satisfactory, Conditional, Unsatisfactory, or None / Not Rated. None / Not Rated is most common (most small carriers haven't been compliance reviewed). Unsatisfactory is rare and disqualifying. |
| Crash Information | Past 24 months of crashes. Number of crashes by severity. Compare against fleet size — 3 crashes for a 50-truck fleet vs 3 crashes for a 3-truck fleet means very different things. |
| Inspection Summary | Roadside inspection count, OOS (out-of-service) violation rate. Industry average: ~20% vehicle OOS rate. Above 30% is a flag. |
The red flags — when to walk away
The minimum due diligence before tendering
Every load. Every carrier. No exceptions:
- USDOT# verified in SAFER
- Operating Authority "Active"
- Insurance on file at the level required by your customer's contract
- BASIC scores reviewed — no category above 80
- Crash and inspection trends reviewed for the last 24 months
- Carrier name on SAFER matches the carrier you're talking to (not a "doing business as" mismatch)
- For new authorities (under 1 year), additional reference check — past customers, freight type they actually haul
For high-value loads (over $100K), high-risk commodities (electronics, pharmaceuticals, copper), or international moves, layer additional verification: factoring company reference, freight reference (a name in their lane history), insurance certificate emailed direct from the agent (not from the carrier).
Cargo theft and double-brokering
Two specific scenarios that SAFER lookups help prevent:
Cargo theft / fictitious pickup
A "carrier" picks up the load with a clean MC# and disappears. The MC# turns out to be hijacked — the real carrier with that MC# has no record of the load. SAFER can't catch this directly (the MC# looks fine), but cross-referencing the carrier's contact info, address, and a phone-call verification to a known number prevents most of it. Brokers should call the carrier's main office at the SAFER-listed phone number — not the cell number the dispatcher provided.
Double brokering
The carrier you booked with secretly re-brokers the load to another carrier. The actual hauling carrier gets paid by the middle-man; the middle-man pockets a fee; you have no contract with the actual carrier. If the load is stolen or damaged, you have no recourse. The signals: the carrier in SAFER doesn't match the carrier whose driver is asking for the pickup, the contracted carrier's MC# is a brokerage authority instead of carrier authority, the pickup driver doesn't know who the broker is.

FreightCoreTMS has FMCSA SAFER lookup built directly into the carrier record. Enter the MC#, the platform pulls the live SAFER data, fills in the carrier name, USDOT, authority status, insurance, and safety summary — and flags red-flag conditions before the carrier becomes bookable.
