What Is a USDOT Number? The Federal ID Every Interstate Mover Needs
A USDOT number is a unique identifier assigned by the Federal Motor Carrier Safety Administration (FMCSA) to commercial motor vehicles and carriers engaged in interstate commerce. Every moving company that operates across state lines must register for a USDOT number — it's how the FMCSA tracks safety records, crash history, and inspection results for every licensed carrier in the country.
Also known as a DOT number or US DOT number, this identifier appears on all federal filings, bills of lading, and moving contracts. For moving companies, it's the foundation of your federal operating identity.
Who Needs a USDOT Number?
Federal law requires a USDOT number for any carrier that operates a commercial motor vehicle in interstate commerce. For moving companies, the key trigger is crossing a state line — even if the move originates in one state and ends in another just a few miles away.
Interstate household goods movers
Any moving company that transports customers' belongings across state lines must have a USDOT number. This applies regardless of company size — one truck or one hundred.
For-hire carriers of regulated commodities
Companies hauling hazardous materials or operating vehicles above 10,001 lbs gross vehicle weight rating (GVWR) in interstate commerce need USDOT registration.
Intrastate carriers (varies by state)
Local movers who never cross state lines aren't required to register with FMCSA, but many states have their own DOT registration requirements. California (CA DOT), Texas (TxDMV), and others have state-level equivalents.
For moving companies: Even if 90% of your jobs are local, a single cross-state move triggers the FMCSA registration requirement. Many movers get caught without proper authority on their first long-distance job.
How to Get a USDOT Number: Step by Step
Registration is completed through the FMCSA's Unified Registration System (URS). The process takes about 30–60 minutes online and the number is typically assigned immediately.
Gather your business information
You'll need your EIN (Employer Identification Number), business legal name, principal business address, type of operation, and vehicle count. Have your state business registration documents handy.
Go to portal.fmcsa.dot.gov
Navigate to the FMCSA Portal and select 'Register for a USDOT Number.' Create an account or log in if you already have one from a previous registration.
Complete the MCS-150 form
The Motor Carrier Identification Report (MCS-150) is the core USDOT registration form. Fill in all fields — company info, commodities hauled, vehicle types, and whether you're also applying for operating authority (MC number).
Receive your USDOT number
Most carriers receive their USDOT number immediately upon submission. The number becomes publicly visible in the FMCSA database within 1–2 business days. Print or save your confirmation.
Apply for operating authority (if needed)
If you'll be transporting household goods for hire across state lines, you also need an MC number (Motor Carrier authority). This is a separate application with a ~$300 filing fee and 4–6 week processing time.
USDOT Number vs. MC Number: Key Differences
These two numbers are often confused, but they serve completely different purposes. Most interstate household goods movers need both.
| Feature | USDOT Number | MC Number |
|---|---|---|
| Purpose | Identifies the carrier | Grants operating authority |
| Issued by | FMCSA | FMCSA |
| Cost | Free | ~$300 filing fee |
| Processing time | Immediate | 4–6 weeks |
| Required for | All interstate carriers | For-hire interstate carriers |
| Tracks | Safety, crashes, inspections | Authorization status |

Ongoing Compliance: What's Required After Registration
Getting your USDOT number is step one. Keeping it active and compliant is an ongoing responsibility. FMCSA conducts regular audits and monitors safety data continuously.
Biennial MCS-150 update
Every two years, carriers must update their MCS-150 form with current company information. The update window opens 6 months before the due date, based on the last two digits of your USDOT number.
Insurance filings (Form MCS-90)
Interstate carriers must maintain minimum liability insurance on file with FMCSA. Household goods movers need cargo insurance plus bodily injury and property damage coverage. Lapses result in automatic authority revocation.
Drug and alcohol testing program
Carriers subject to FMCSA regulations must maintain a DOT-compliant drug and alcohol testing program for all safety-sensitive employees, including drivers. Random testing rates are set annually by FMCSA.
Safety rating maintenance
FMCSA assigns carriers a safety rating (Satisfactory, Conditional, or Unsatisfactory) based on compliance reviews and roadside inspections. An 'Unsatisfactory' rating triggers a notice to cease operations.
