What Is the FMCSA Census File?

The Official Carrier Registry

The FMCSA Motor Carrier Census File (the dataset many know by its data.transportation.gov ID, az4n-8mr2) is the federal government's master record of every registered motor carrier in the United States.

What the Raw File Contains

DOT numbers, legal and DBA names, addresses, fleet sizes, operation classifications, and cargo authorities — over 1.6 million active carrier records, plus millions of inactive ones you'll need to filter out.

The Catch With the Raw File

It ships as a massive raw export with cryptic column codes, mixed active/inactive records, and patchy contact fields. Plan on hours of cleanup before it's usable for outreach.

The Cleaned Alternative

We compile the census file into a ready-to-use CSV — active carriers only, emails and phones included, segmented by state and cargo type. One-time $99, instant download.
