What Are USDOT Numbers?
Published by Joe Webster.

The Federal Motor Carrier Safety Administration – FMCSA
The Federal Motor Carrier Safety Administration, or the FMCSA, is a division established in January 2000 as an integral part of the United States Department of Transportation (U.S. DOT). The FMCSA regulates the trucking industry in the United States, with the primary objective of improving the safety of commercial motor vehicles and truck drivers that operate them. The goals of the FMCSA are attained through enacting and enforcing safety regulations. Any company that serves commercial motor vehicles carrying passengers or hauling cargo between states must register with the FMCSA and obtain a Number.
What happens when a company registers with FMCSA?
When a company that conducts business across state lines or carries passengers between states registers with the FMCSA, they must obtain a number. The USDOT Number is unique to each company. This number tracks the data regarding a company’s safety information obtained through audits, inspections, compliance reviews, and accident investigations.
Upon application, any first-time carrier will automatically enroll in the FMCSA New Entrant Safety Assurance Program. The entrant will not receive permanent registration status until they have been in the program for 18 months. During this initial period, the new entrants must pass a safety audit within the first 90 days. Additionally, the company must maintain acceptable roadside safety performance during the probationary period.
All my business is intrastate. Why do I need a USDOT Number?
Thirty-one states also require a number for commercial vehicle registrants regardless of whether or not their business is conducted between states. Those states are Alabama, Alaska, Arizona, Colorado, Connecticut, Florida, Georgia, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Michigan, Minnesota, Missouri, Montana, New York, Nebraska, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, Tennessee, Texas, Utah, Washington, West Virginia, Wisconsin, and Wyoming.
It should be noted that if a company operates strictly as a broker or freight forwarder, obtaining a USDOT Number is unnecessary.

How do I get my USDOT Number?
Companies can apply for a Number by going to the FMCSA website, www.fmcsa.dot.gov, for information. You can also reach the FMCSA by calling their toll-free number, 1-800-832-5660. Each state also has a local Department of Transportation or FMCSA field office. You must complete the provided forms, including the MCS-150 or MCS-150B. Online registration is encouraged by the FMCSA, but a docket number and PIN will need to be obtained before registering. The FMCSA assists with online registration with a helpful step-by-step guide that can be found on their website.
What do I do with my USDOT Number?
When a company obtains a number, it must be visibly displayed on every commercial motor vehicle within its fleet, which is required by law to display the number. Because the purpose of the USDOT Number is to track safety data, it allows the average driver an identifier to locate the company and report unsafe operators. Vehicles operating with faulty or dangerous equipment can also be reported to the company to which the USDOT Number belongs. The number provides a universal mechanism for reporting unsafe driving actions and any safety issues related to a commercial motor vehicle.
How Do I Find a Company’s USDOT Number?
The U.S. Department of Transportation has a website that allows users to search by number. If you have a number and want to receive information about the company to which the number belongs, you can go to http://safer.fmcsa.dot.gov/CompanySnapshot.aspx to obtain that information. Type in the number in the search box and ensure the number option has been selected.
