U.S. DOT Number
Who Needs a U.S. DOT Number & How to Get One
Motor carriers operating commercial vehicles across state lines can find info and help at the FMCSA's Office of Registration website.
Iowa-based for-hire intrastate carriers need a USDOT-IA number and must contact Iowa DOT's Motor Carrier Services at 515-237-3268 for assistance.
Carriers with a USDOT number for interstate commerce wonβt get a second number but must obtain intrastate operating authority for Iowa loads.
