Do I Need a DOT Number and MC Authority… or Just One?

If you’re planning to go independent, one of the first things you’ll hear about is the DOT Number and MC Authority. But no one explains the difference in plain English.


Do you need both? Does one come first? What do they even mean?


Let’s break it down—real talk, no government jargon.

What’s a DOT Number?

Your DOT Number is your trucking ID with the federal government. It tracks your company’s safety record, inspections, and compliance.
If your truck is over 10,000 lbs, you need it—period.

You need a DOT Number if:

- You’re hauling loads for pay

- Your truck weighs over 10,000 lbs

- You’re operating in Texas or out of state


What’s MC Authority?

MC stands for Motor Carrier. Your MC Authority gives you permission to haul freight for others across state lines.
Without it, you can’t work with brokers or get paid as an independent carrier.

You need MC Authority if:


- You’re running your own show

- You want to cross state lines

- You’re not leased onto someone else


What’s the Difference?

- DOT = Your ID number

- MC = Your permission to get paid hauling freight for others


You usually apply for both at the same time if you’re starting your own business.


What If I’m Only Hauling in Texas?

If you’re doing in-state freight only, you may only need a DOT Number + Texas DMV registration.
But if you plan to cross into Louisiana, Oklahoma, or anywhere else—you need MC Authority too.

The Bottom Line

Leased onto a carrier? → They cover it.

Running your own authority? → You need both.

Crossing state lines for freight? → You need both.
