Free carrier lookupDOT and MC number lookup

Check any trucking company's authority, insurance and safety record with live FMCSA data.

Data from the Federal Motor Carrier Safety Administration (FMCSA): the QCMobile service and the FMCSA Company Census on data.transportation.gov. Census data is about a day behind and results may be cached for up to 12 hours. Always confirm on the official FMCSA website before making business decisions.

Enter a USDOT number, an MC number or a company name to see whether a carrier or broker is allowed to operate, which authorities are active, what insurance is on file with FMCSA, and its inspection and crash record.

How to read the results

  • Allowed to operate shows whether FMCSA currently lets the company operate.
  • Common, contract and broker authority show which types of operating authority are active.
  • Insurance on file shows the liability and cargo coverage filed with FMCSA, next to the amount required.
  • Safety rating is Satisfactory, Conditional or Unsatisfactory, or Not rated if FMCSA has not done a compliance review.
  • Inspections and crashes show recent roadside history.
  • MCS-150 outdated means the company has not updated its registration on time.

Who uses a carrier lookup

Owner-operators check brokers before booking a load. New carriers confirm their own authority and insurance filings went through. Shippers and brokers vet carriers before handing over freight.

Questions about DOT and MC lookups

What is a DOT number?

A USDOT number is a unique number FMCSA gives a company that operates commercial vehicles. It is used to track the company's safety record, inspections, crashes and compliance.

What is an MC number?

An MC number is the docket number for a company's interstate operating authority. Carriers that haul regulated freight for hire across state lines need operating authority, and brokers have their own broker authority.

Where does this data come from?

From FMCSA's official QCMobile service, the same government data behind the SAFER system. We cache results for up to 12 hours, so always confirm on the official FMCSA website before making a business decision.

What does 'allowed to operate' mean?

It means FMCSA currently shows the company as allowed to operate. A company can be blocked if its authority is revoked, its insurance lapses or it is placed out of service.

How do I check a broker before hauling a load?

Search the broker's MC number, then check that broker authority is active and look at its record. Many carriers also check broker credit and payment history before booking.
