USDOT & MC Number Lookup

How to Vet a Carrier or Broker Before You Hand Them a Load

Before you hand a load to a carrier you have never worked with, spend five minutes checking the public record. A carrier that looks legitimate on a load board can be operating without authority, parked under an out-of-service order, or borrowing another company's identity, and once your freight is on their trailer your leverage is mostly gone. The lookup tool above opens the carrier's official Federal Motor Carrier Safety Administration (FMCSA) record, and the checklist below tells you exactly what to read in it. Use the same routine every time, even for carriers a broker recommends, and keep a note of what you checked in case a claim or a payment dispute comes up later.

Start with the FMCSA SAFER Company Snapshot

The SAFER Company Snapshot is the carrier's public safety record. Open it from the tool above and start with the legal name, the physical address, and the USDOT and MC numbers. All four should match the carrier you are talking to, letter for letter. A different legal name, a P.O. box where a street address should be, or a DOT number that belongs to a different company is a reason to stop and ask questions before you book anything. Then read the operating authority status. For interstate for-hire freight it must say AUTHORIZED. Anything else, such as NOT AUTHORIZED, INACTIVE, or REVOKED, means the carrier is not legally allowed to haul your load, and your cargo insurance may not respond if something goes wrong.

Next, check the two fields that describe whether the carrier is allowed on the road at all. Out-of-service must say No, and the safety rating is worth reading in full: SATISFACTORY is the best outcome, CONDITIONAL means the carrier has had compliance problems and deserves extra scrutiny, and UNSATISFACTORY means the carrier should not be operating. Also check the date of the last MCS-150 biennial update. A current filing shows the carrier is keeping its registration up to date; a stale one is a small warning sign on its own, and a bigger one when it appears alongside other problems. If the snapshot shows very few inspections or a very short operating history, that is not proof of wrongdoing, but it is a reason to look harder at the rest of the record. You can cross-check a carrier against the other free checks on our Tools hub, including the Authority Checker for Texas intrastate authority.

Check Licensing and Insurance for the BMC-91 and BOC-3

Authority is only half the story. In FMCSA Licensing and Insurance, look for the carrier's insurance filings. The BMC-91 is the public liability filing, and for general freight it must be active at the required level, a minimum of $750,000 for most general freight and higher for hazardous materials and certain other cargo. If the BMC-91 is missing, cancelled, or below the required amount, the carrier is not properly insured for your load, no matter what a certificate of insurance says. While you are there, confirm the BOC-3 process agent filing is in place; without it, there is no registered agent to accept legal papers on the carrier's behalf in each state, which makes any claim much harder to pursue. Finally, confirm the authority type matches the work: common and contract authority cover different arrangements, and a carrier with only household-goods authority, for example, should not be hauling your general freight.

Watch for Double-Brokering Red Flags

Double brokering, when a carrier or broker accepts your load and quietly hands it to another carrier without telling you, is one of the most expensive risks in trucking, and the SAFER record is often where the warning signs first appear. Be cautious when the authority is very new, sometimes only days or weeks old, yet the carrier is pressuring you to book quickly, to release the load the same day, or to accept quick-pay terms you did not agree to. Be equally cautious when the name or address on the rate confirmation does not match the SAFER record, or when the company asking to be paid is a different name from the carrier of record. Other red flags include a carrier that will not share its insurance information, a dispatcher who cannot tell you where the truck is, or a rate that is far below the market for the lane with no plausible explanation. One red flag on its own may have an innocent explanation; two or three together are a reason to walk away and find another carrier, however tight the deadline feels.

• Authority is very new, but the carrier is pressuring you to book fast or accept quick-pay terms.
• The name or address on the rate confirmation does not match the FMCSA record.
• The company asking to be paid has a different name from the carrier of record.
• The carrier will not share insurance details or cannot say where the truck is.

Good vetting is not about finding a perfect carrier. It is about refusing to hand freight to a carrier you cannot verify. Run the lookup, read the snapshot, confirm the insurance, and trust the red flags. The five minutes it takes are cheap compared with a lost load, an unpaid claim, or a week spent chasing a company that never existed on paper. If you are a new carrier yourself, the same records matter from the other side: keep your MCS-150 current, your insurance filings active, and your information consistent everywhere it appears, and take our Safety Audit Quiz to check whether you are ready for a new-entrant safety audit.

Frequently Asked Questions

Is this lookup free?

Yes. This USDOT number lookup is completely free to use, and so are the official FMCSA records it links to. There is no account to create and nothing to pay. Enter a USDOT number, MC number or legal company name, open the carrier's SAFER snapshot and Licensing & Insurance record, and work through the guided checklist as often as you need.

What does AUTHORIZED authority status mean?

AUTHORIZED means the carrier holds active FMCSA operating authority to carry interstate for-hire freight. It is the status you want to see before you book a load. NOT AUTHORIZED, INACTIVE or REVOKED means the carrier is not legally allowed to haul your freight, and your cargo insurance may not respond if something goes wrong, so do not book a carrier in any of those statuses.

Where does the carrier data come from?

The carrier data comes directly from the FMCSA's own public systems, not from Trucking Mind. This tool builds links to the official SAFER Company Snapshot at safer.fmcsa.dot.gov and the FMCSA Licensing & Insurance system at li-public.fmcsa.dot.gov. Nothing is copied or stored on this page, so always read the live record on the FMCSA site, as filings can take time to appear after a carrier updates them.

What should I do if a carrier shows no insurance filing?

Do not hand the carrier your freight until the filing is verified. In Licensing & Insurance, look for an active BMC-91 liability filing at the required level, usually $750,000 for general freight and $1 million for certain hazardous materials. If the filing is missing, cancelled or below the required level, ask the carrier for proof of insurance and re-check the record. If it still cannot be verified, walk away, and tell the broker if the load was brokered to you.
