How to Get a USDOT Number and MC Authority: Step-by-Step for New Carriers

Before you haul a single paid load across state lines, you need two things from the Federal Motor Carrier Safety Administration (FMCSA): a USDOT number and, for most for-hire carriers, operating authority, still widely called an "MC number." The process is not complicated, but the order matters, and one missing filing can leave you sitting with a truck payment and no legal way to run. Here is how to get both, step by step, as of 2026.

Warning: FMCSA rules and systems change. Verify every step and fee on fmcsa.dot.gov before you apply. This is general information, not legal advice.

USDOT number vs operating authority

If you only haul your own goods (a private carrier) or only exempt commodities, you may need a USDOT number but not operating authority. Read FMCSA's guidance for your exact operation.

What about the MC number changes?

In May 2026, FMCSA replaced its legacy registration portal with a new system called Motus. As of late 2026, FMCSA still issues MC docket numbers there. FMCSA has proposed eventually making the USDOT number the only identifier, but that requires rulemaking and had not taken effect at the time of writing. Check FMCSA's Registration Modernization FAQ for current status.

Before you apply: get these ready

• ☐ Business entity formed (many owner-operators use an LLC)
• ☐ EIN from IRS.gov
• ☐ Principal place of business address (a real address, not just a PO box)
• ☐ Mailing address, phone and email
• ☐ Company officer names and details
• ☐ Government-issued photo ID for identity verification
• ☐ Number of power units and drivers
• ☐ Cargo types and operation type (for-hire, private, exempt)
• ☐ An insurance agent who writes new-authority policies, already quoting

Tip: Start insurance quotes before you apply. Insurance is the step that usually holds up activation, and the quotes may change your truck or freight plan.

Step-by-step: getting your authority

Step 1: Create your Motus account

Go to FMCSA's registration system, create an account and complete identity verification. FMCSA added stronger identity checks to fight fraud, so make sure names and details match your official documents exactly.

Step 2: Apply for the USDOT number and operating authority

Complete the application with your company details, operation type and cargo. Choose the authority type: for most truckers, motor carrier of property. Pay the $300 fee per authority type. Fees are non-refundable.

Step 3: Receive your numbers

You will receive a USDOT number and docket number. Your authority is not active yet. Expect a surge of calls and emails from sales companies the moment your information is published. Be cautious and never pay anyone claiming to be FMCSA by phone.

Step 4: Have your insurer file proof of insurance

Your insurance company files proof of liability coverage with FMCSA (Form BMC-91 or BMC-91X), and cargo coverage (BMC-34) where required. The federal minimum public liability for general freight in vehicles of 10,001 pounds or more is $750,000, but most brokers and shippers require $1,000,000 in auto liability and often $100,000 in cargo.

Step 5: File the BOC-3

The BOC-3 designates process agents in each state who can receive legal documents on your behalf. Most new carriers use a blanket process agent company, often for $25 to $100 one-time.

Step 6: Wait out the protest period

After publication, there is a waiting period (historically 21 days, verify current rules) during which others can protest. Most new authorities are not protested.

Step 7: Confirm active status

Check FMCSA's SAFER and Licensing and Insurance (L&I) public sites. When your authority shows as active and insurance and BOC-3 are on file, you can haul for-hire interstate loads.

A worked example: registration budget and timeline

An owner-operator with one used tractor and trailer, hauling dry van:

Typical time to active authority: three to six weeks. Add IRP plates, IFTA, the Form 2290 heavy vehicle use tax and ELD setup alongside these filings.

The state credentials you need alongside your authority

Federal authority lets you operate as a for-hire carrier. State credentials let you run legally on each state's roads and pay each state its share of registration and fuel tax.

Your IRP office usually wants proof of your USDOT number and Form 2290 before issuing plates, so these steps overlap. Many new carriers apply for IRP and IFTA while they wait for the federal protest period to end, so everything lands at roughly the same time.

Tip: Keep a single folder, digital and paper, with your authority letter, insurance certificates, BOC-3 confirmation, IRP cab card, IFTA license, UCR receipt and stamped Schedule 1 from Form 2290. Brokers, auditors and roadside inspectors will all ask for pieces of it.

After activation: the new entrant period

Your first 18 months are a probationary new entrant period. FMCSA or a state partner will conduct a safety audit, usually within the first 12 months. Be ready to show:

• Driver qualification files
• Hours-of-service records from your ELD
• Drug and alcohol testing program enrollment and Clearinghouse queries
• Maintenance and inspection records
• Accident register
• Proof of insurance

Some violations are automatic failures, such as using a driver without a valid CDL or having no drug and alcohol testing program.

Ongoing requirements to calendar

• MCS-150 biennial update every two years, even if nothing changed
• UCR annually
• IFTA quarterly fuel tax returns
• Form 2290 annually for heavy vehicles
• Insurance renewals, with continuous filing on record

Mistakes to avoid

• Hauling before authority shows active
• Letting insurance lapse, which can revoke authority
• Using a residential address that does not match records
• Paying "compliance" callers who imitate FMCSA
• Skipping the drug and alcohol consortium before your first load
