US DOT Number ─ United States Department of Transportation Number

​

Companies that operate commercial vehicles, transporting passengers, or hauling cargo in interstate commerce must be registered with the FMCSA and must have a US DOT Number. The US DOT Number serves as a unique identifier when collecting and monitoring a company's safety information acquired during audits, compliance reviews, crash investigations, and inspections. Whether you are becoming an Interstate Motor Carrier or just registering your vehicle under International Registration Plan (apportioned plates), you will have to obtain this number. In addition, obtaining US DOT Number is a must for intrastate carriers in the following states: Alabama, Alaska, Arizona, Colorado, Florida, Georgia, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Michigan, Minnesota, Missouri, Montana, New York, Ohio, Oklahoma, Oregon, South Carolina, Tennessee, Texas, Utah, Washington, West Virginia, Wisconsin, and Wyoming.
