Federal DOT Number
Before entering the State of California, a trucker must have a federal Department of Transportation (DOT) Number. As part of the registration process, you must provide your Federal ID number if you are involved in transportation services as a motor carrier.
How To Obtain A U.S. DOT Number
The Federal Motor Carrier Safety Administration (FMCSA) issues USDOT numbers. Please see the following FMCSA web sites:
General FMCSA phone number: 1-800-832-5660.
Sacramento FMCSA phone number: (916) 930-2760.
How To Locate a Company
See the FMCSA web site: "SAFER - Safety and Fitness Electronic Records System." To find a company, click on the link "Company Snapshot" in the middle column. You can search by USDOT number, MC/MX Number, or company name.
In-State Carriers: An in-state carrier operating a commercial vehicle within California must obtain a Motor Carrier Permit, a CA number, and as of September 2016 a U.S. Department of Transportation (DOT) Number as well. See Federal Motor Carrier Safety Administration website: US DOT Number.
Out-Of-State Carriers: Some out-of-state carriers must obtain a Motor Carrier Permit and a CA number in addition to the U.S. DOT number to come into California. For more information on who must obtain a Motor Carrier Permit, see the website: Motor Carrier Permit.
