What Is a DOT Number?
A DOT number (USDOT number) is a unique identifier assigned by the Federal Motor Carrier Safety Administration (FMCSA) to every commercial motor carrier operating in interstate commerce. It's used to track safety information, inspections, compliance reviews, and crash history.
Every carrier must display their DOT number on both sides of their power units. It's also required for all FMCSA registrations, insurance filings, and compliance paperwork.
How to Read Your Carrier Profile
Legal Name vs DBA
Your legal name is what FMCSA has on file from your MCS-150. Your DBA (doing business as) is optional — it's the name you operate under if different from the legal entity.
Entity Type
This tells you how you're classified: carrier, broker, or both. Most truckers are "CARRIER" — if you see something unexpected, your registration may need updating.
Power Units & Drivers
These numbers come from your last MCS-150 update. If they're wrong, file an updated MCS-150 with FMCSA. Inaccurate numbers can trigger compliance flags.
