609,939 New USDOT Numbers Since 2018
An objective analysis of address, name, and email trends in carrier registrations.
Since 2018, 609,939 new USDOT numbers have been registered with the U.S. Department of Transportation.
The dataset analyzed excludes bus and car service companies and includes only entities marked as “Authorized For Hire.” In other words, these are trucking companies authorized to haul freight commercially.
The registration data contains basic company information, including the physical address, the name of the company officer, and the company's email address. While seemingly routine, a closer examination reveals statistical patterns that stand out, particularly when compared to U.S. Census data and common business practices.
This article does not offer conclusions or accusations. It presents the data as-is: highlighting the most frequent last names, the widespread use of non-professional email domains, and instances of reused contact information across multiple companies.
In a sector where safety, trust, and accountability are critical, these patterns warrant attention.
