USDOT Number vs MC Number: What a Legitimate Mover Holds

Moving Union Standards Team7 min readUpdated July 2026

People searching for a "DOT registered moving company" are asking the right question with slightly the wrong vocabulary. A USDOT number and an MC number are two different credentials, a company can hold one without the other, and neither one on its own proves the company is allowed to move your household goods. Here's what each actually means and what to check.

What a USDOT number is

A USDOT number is a federal identifier for a commercial motor carrier. It's how the Federal Motor Carrier Safety Administration tracks a company's safety record, inspections, crashes, and compliance reviews. Any company operating commercial vehicles in interstate commerce needs one, and many states also require a USDOT number for purely intrastate carriers. Think of it as the company's federal file number: it identifies who they are, and it's the key you use to look everything else up.

What an MC number adds

An MC (motor carrier) number is operating authority, permission to transport regulated commodities for hire across state lines. That's a different thing from identification. A carrier hauling only its own goods, or operating only within one state, may have a USDOT number and no MC number at all, and be entirely legitimate. For an interstate household-goods move, though, you want to see both the identifier and the authority.

The distinction in one line each

USDOT number: who the carrier is, and the file where its safety and insurance record lives.
MC number: operating authority, permission to haul regulated freight for hire across state lines.
Household goods (HHG) authority: the specific permission to move your furniture, the part most people never check.
State authority: what an in-state move runs under instead, issued by a state regulator rather than the FMCSA.

Household-goods authority is the part that matters

This is the check almost nobody makes. Plenty of carriers hold an active USDOT number and active operating authority for general freight, and are not authorised to move household goods. On the FMCSA Company Snapshot, authority is broken out by type, and "HHG" is what you're looking for on an interstate move. A mover with authority for property but not household goods is not the right company for your home, regardless of how active its record looks at a glance.

How to read a Company Snapshot

01
Search the number, not the name
Go to safer.fmcsa.dot.gov and search the USDOT number from the mover's estimate. Names get reused and rebranded; the number doesn't.
02
Check operating status
You want 'active'. Inactive, out-of-service, or revoked means the company is not currently authorised to operate, whatever its website says.
03
Confirm the authority type
Look for household-goods authority specifically if your move crosses a state line. General property authority is not the same permission.
04
Look at the insurance section
The snapshot shows whether the required coverage is on file. Filed insurance is a minimum, not a guarantee, but a gap here is disqualifying.
05
Read the registration date
An MCS-150 registration filed last year under a company advertising twenty years of experience is worth a hard question. Re-registration is how a bad record gets shed.

What if my move never leaves the state?

Then federal authority may not be the relevant credential at all. An intrastate household-goods move is regulated by your state, and the licence goes by a different name in each one, a utilities commission certificate, a state permit, a DMV registration. Some intrastate movers carry a USDOT number too, but the state licence is the one that governs the job. See how to check a mover's licence in your state for the specific regulator where you're moving.

Verifying all of this is the first of the five checks we run before any company can receive your request, see how we vet movers. The records are public, though, and you should confirm them yourself before you sign anything.

Frequently asked

Is a USDOT number the same as an MC number?

No. A USDOT number identifies the carrier and is the key to its federal safety and insurance file. An MC number is operating authority, permission to haul regulated commodities for hire across state lines. A company can legitimately hold a USDOT number without an MC number, but for an interstate household-goods move you want to see active authority for household goods specifically.

What does household-goods authority mean?

It's the specific federal permission to transport household goods, as opposed to general freight. On the FMCSA Company Snapshot, authority is listed by type, and a carrier can be fully active for property while not being authorised for household goods. For an interstate move of your home, that's the line to check.

Does a local mover need a USDOT number?

Not always. A move that stays inside one state is regulated by that state, so the mover needs the relevant state operating authority, which might be a utilities commission certificate, a state permit, or a DMV registration depending on where you live. Many intrastate movers also carry a USDOT number, and some states require it, but the state licence is what governs a purely local move.
