USDOT and MC Numbers

This is the practical money page: what you’re applying for, what it costs, how to apply, and how long you’ll wait.

Do You Need a USDOT Number?

Yes, if any of these apply to you:

• Your gross vehicle weight rating (GVWR) or gross combination weight rating (GCWR) is 10,001 lbs or more
• You transport 8 or more passengers for compensation
• You transport 15 or more passengers not for compensation

If none of these apply, you likely don’t need a USDOT number at the federal level (though your state may require one).

Most small carriers moving freight will hit the 10,001-lb threshold, so assume you need one.

Cost: Free.

Do You Need Operating Authority (MC/FF/MX Number)?

Operating Authority is the docket number that lets you be for-hire. You need it if:

• You haul freight or passengers for compensation on behalf of others (definition of “for-hire”)

You do NOT need it if:

• You’re a private carrier hauling only your own goods
• You operate only within an exempt commercial zone

If you need it: Operating Authority comes in three types:

• MC (Motor Carrier): The standard authority for a for-hire motor carrier of property or passengers — covers most US-based freight and passenger operations.
• FF (Freight Forwarder): Arranging transportation for others without owning or operating the trucks yourself.
• MX: Authority for Mexico-domiciled carriers operating beyond U.S. border commercial zones (filed on paper Form OP-1 MX, not through the standard online process). This does not apply to US-based carriers.

Pick the authority type(s) that match your actual business. Filing for the wrong one costs you money, and you can’t get a refund.

Cost: $300 per authority type (one-time filing fee for permanent authority). Name changes are $14. Reinstating a lapsed authority is $80. There are no refunds if you file incorrectly.

How to Apply

For first-time applicants: Use MOTUS, the system covered in What Is MOTUS?. Create a Login.gov account, verify your identity via IDEMIA, and submit your application online.

For existing carriers adding authority: You can still apply via MOTUS, or use the legacy system with a credit card (if that option is still available in your state — check with FMCSA first).

How Long Does It Take?

New URS applications (Motus): 20–25 business days, assuming your application is complete and doesn’t get flagged for review. If it does get flagged (which happens sometimes), processing can stretch to 8+ weeks while FMCSA investigates.

Mail-in applications from existing carriers: 45–60 business days.

Your timeline depends on whether FMCSA has questions about your application. Make sure every detail is accurate — mistakes slow things down.

Your Authority Isn’t “Active” Yet

Here’s the critical step that catches most new carriers off guard: getting approved for operating authority doesn’t mean you can start hauling.

Your authority won’t go “Active” until you also file and get accepted for:

1. BOC-3 (Blanket of Coverage): You must designate a process agent in every state you operate in. This person is your legal representative for service of process (lawsuits, regulatory notices, etc.). Most carriers use a registered blanket company to handle this. Cost: roughly $20–$100/year for nationwide coverage.

2. Insurance: You must file proof of insurance with FMCSA. The minimum varies by commodity and operation type, but most interstate for-hire carriers need at least $750,000 in liability coverage.

These aren’t optional add-ons — your authority literally won’t activate until both are filed and accepted.

The next article, BOC-3 and UCR, covers both of these in detail.

Need Help?

If you’re navigating MOTUS for the first time, consider working with a registration service. Many specialize in filing USDOT and operating authority applications, and can catch errors that slow you down. Find options in Registration Services.

What’s Next

Once your authority is approved, you still need to complete the final steps. Read BOC-3 and UCR to understand how those two final requirements work — and why they can silently revoke your authority if they lapse.
