Verify a USDOT number by inputting the number into the U.S. Department of Transportation's SAFER system. After entering a USDOT number, MC/MX number or company name in the tool, a company snapshot appears if the company legitimately holds a USDOT number.
If the company does not possess a USDOT number, the results page indicates that there are no records in the SAFER database matching the inputted USDOT number. The company snapshot contains an electronic record of the companies' identification, safety record, crash information and a roadside out-of-service inspection summary. It also indicates the company's size and commodity information. The Federal Motor Carrier Safety Administration of the U.S. Department of Transportation provides free access to the SAFER system.
