How to Look Up a Trucking Company

Every interstate carrier is assigned federal identifiers, and most can also be found by company name. Start with whatever the carrier gives you. All three paths lead to the same federal record.

• By MC number. The motor carrier (MC) number is what a broker usually has from the rate confirmation or carrier packet. It maps to the carrier's interstate operating authority. See our MC number lookup walkthrough.
• By DOT number. The USDOT number is the carrier's permanent federal ID and the one tied to safety and inspection data. A carrier with a DOT number but no MC may run intrastate only. See our DOT number lookup guide.
• By company name. If all you have is a name off an email or a truck door, search by name to find the number, then verify. Watch for near-identical names, a common impersonation tactic. See our carrier lookup by name guide.

Looking up a trucking company is not just confirming it exists. The federal record answers the four questions that decide whether a load is safe to tender.

• Operating authority. Is the company authorized to haul, and for what (common, contract, broker, property vs. household goods)? Authority should be active. Revoked or pending authority is a reason to stop and dig deeper.
• Insurance on file. Does the carrier have the required liability and cargo coverage filed with the FMCSA? On-file is a baseline, not proof a policy is paid up, so a current certificate direct from the insurer still matters.
• Safety rating. Satisfactory, Conditional, Unsatisfactory, or, very often, unrated. An unrated carrier is not automatically bad, but it means you cannot lean on a rating and should weigh the other signals harder.
• Out-of-service status. Has the carrier or its trucks been ordered out of service? An out-of-service order means the company cannot legally operate right now.

• 1. Enter the number. Type the MC or DOT number into the lookup, or search by name and pick the match.
• 2. Confirm the name matches. Check that the legal and DBA names line up with the company you are actually talking to. A mismatch between the email domain, the number, and the registered name is a red flag.
• 3. Read authority and out-of-service first. If authority is not active or there is an out-of-service order, stop and resolve it before you book.
• 4. Check insurance and safety. Confirm coverage is on file and note the safety rating. Then get a certificate naming you, tied to the live policy.
• 5. Save the record. Keep a dated copy of what you saw at the time you booked. If something goes wrong later, that snapshot documents what you reviewed.

A free lookup answers the basic yes/no questions and is enough for an occasional check. The free CarrierClear tool returns authority, insurance on file, safety rating, and out-of-service status by MC or DOT number, plus a dated PDF vetting record, with no account needed.

Paid tiers add depth and memory. Paid lookups add a risk rating that always lists the exact reasons behind it, the full insurance picture (on file vs. required for liability and cargo, plus bond), out-of-service rates versus the national average, crash and inspection history, OFAC sanctions screening, phone and address screening, and an identity-reuse flag that catches a carrier reusing an EIN or operating under a fresh shell. You also get ongoing monitoring with email alerts and a dated change log, so you find out when a carrier you already booked loses authority or insurance, instead of finding out from a claim. Plans start at $49/mo.

A clean federal record is necessary, not sufficient. The underlying data is public FMCSA information, so it can lag, and a sophisticated fraudster can present real numbers that belong to someone else. That is why matching the contact details to the registered carrier, and screening the phone and address, matter as much as the authority line.

CarrierClear is an information tool built from federal records plus third-party phone and address screening on paid tiers. It does not certify a carrier, it is not legal advice, and it does not host anonymous reviews or reports, on purpose, so what you see is verifiable data, not unaccountable rumor. Use the lookup to make a faster, better-documented decision, not to outsource the decision.
