Introduction
Thinking about running your own trucking business? Getting your DOT number is one of the first legal steps you’ll need to operate under your own authority. Whether you’re an owner-operator breaking out on your own or a small fleet just getting started, knowing how to apply for your DOT number properly can save you time, money, and headaches down the road. In this quick guide, you’ll learn exactly how to get a DOT number, who needs one, and what to watch for along the way.
What Is a DOT Number and Who Needs One?
A USDOT number is your unique ID with the Federal Motor Carrier Safety Administration (FMCSA). Think of it like your trucking business’s fingerprint, it tracks your safety record, compliance history, and other key info.
You’ll need a DOT number if you:
- Operate a commercial vehicle over 10,000 lbs. (GVWR) in interstate commerce
- Transport hazardous materials that require a safety permit
- Or if your state requires a DOT number for intrastate carriers (many do!)
If you’re just hauling under someone else’s authority, you might not need your own DOT number yet, but if you’re getting your own new trucking authority, it’s a must.
How To Get a DOT Number: Step-by-Step
Getting your DOT number is pretty straightforward, but small mistakes can delay your operating authority. Here’s how to do it right:
1. Gather Your Info
Before you apply, have this ready:
- Legal business name and address
- Employer Identification Number (EIN) or Social Security Number
- Details about your vehicle(s) and operation type
- Driver info and safety certifications
2. Register with the FMCSA (Online)
Go to the FMCSA’s Unified Registration System (URS): FMCSA URS Portal.
Create an account and follow the steps to file your application (Form MCS-150).
3. Pay Required Fees (If Any)
The DOT number itself is free, but you’ll likely also be applying for Motor Carrier Authority (MC number) at the same time, which does require a fee (currently around $300).
4. Wait for Processing
Once submitted, you’ll get your USDOT number immediately, but your MC authority can take 20–25 business days to activate. Watch for any errors or requests for more info.
5. Display Your DOT Number
When approved, you must display your DOT number on both sides of your truck, in contrasting colors, and at least 2 inches tall.
Pros, Cons & What to Watch Out For
Pros of getting your own DOT number:
- Full control over your business and loads
- More negotiating power with brokers
- Build your own safety and compliance record
Cons to keep in mind:
- You’re responsible for all compliance, safety, and reporting
- Startup costs (insurance, filings, ELDs) can add up fast
- Penalties for non-compliance are steep
👉 Watch out for: shady third-party services that charge hundreds to “file for you.” Always double-check you’re on the official FMCSA site!
What This Means for New Owner-Operators
Having your own DOT number means you’re the boss, but you’re also on the hook for staying legal. If you’re not ready to run under your own authority yet, many drivers lease onto a reputable carrier first to gain experience and save on upfront costs.
