How do I check a trucking company's MC and USDOT number?

What is a USDOT number?

An identifier FMCSA assigns to companies subject to federal motor-carrier registration and safety requirements. It is not the same thing as operating authority, and that difference matters.

What is an MC number?

An MC number has long been the docket number for operating authority FMCSA grants for for-hire interstate work (brokers and forwarders have their own authority types). FMCSA has been moving registration toward the USDOT number as the single identifier, so some newer companies may show authority against their USDOT number without a separate MC number. Either way, a number someone quotes to you is not verification: look at the actual federal record.

What should I compare first?

• Legal name — does it match the company communicating with you?
• USDOT status — SAFER explains active, inactive and out-of-service statuses.
• Operating authority — for a for-hire interstate property carrier, the record should show the authority status that applies; SAFER distinguishes authorised, not authorised and out of service.
• Authority numbers — confirm the MC, MX or FF numbers shown in the record.
• Address and phone — compare them with what you were given. A mismatch is not proof of fraud (companies have agents, and records lag), but an unexplained one deserves checking.

Where do I check insurance?

From the company's SAFER record, follow the Licensing & Insurance information. Do not rely on an emailed screenshot, a copied certificate alone or an MC number in an email signature. What a filing covers is a separate question: FMCSA does not require most general-freight carriers to file cargo insurance at all. See freight insurance vs carrier liability.

Does an active USDOT number mean the carrier is authorised for my load?

Not necessarily. USDOT status and operating authority answer different questions, and a record can show an active USDOT number with no authority for interstate for-hire work. Check the entity type and the authority that applies to the job.

Does a safety rating of "None" mean the carrier is safe?

No, and it does not mean unsafe either. Many carriers have no federal safety rating. Do not turn missing data into a conclusion in either direction; use the actual record and your own verification criteria.

What do inspection and crash numbers tell me?

They are pieces of public history. FMCSA notes that reported crashes show involvement and do not by themselves determine fault. Inspection and out-of-service rates need context: how many inspections, what kind of operation, fleet size and the time period. We do not turn these fields into our own safe or unsafe score, and neither should a single glance.

What if the company name does not match?

Stop and verify. It could be a DBA, an affiliated company, a factoring or payment name, outdated information, a simple mistake, or impersonation. Do not assume which. Ask, and independently confirm the operating company before tendering freight.

What if the phone or email does not match SAFER?

Treat it as a signal to verify, not automatic proof of fraud. Carrier identity theft makes independent checks important: call a number you found yourself, not the one in a suspicious email. Brokers run their own, deeper process: see how does a freight broker check a carrier?

Can I search by company name?

Yes. Name searches can return several similar companies, so confirm the legal name, address, USDOT and MC numbers and authority before assuming you found the right one.

What should a shipper save?

The carrier and broker identification provided for the shipment, plus the identifiers you checked and when. Do not copy federal safety data into a file and let it go stale: the live FMCSA record is the source.
