How to Get an MC Number in 2026: Step-by-Step Guide

By Authority Launcher · Updated October 29, 2026

Quick answer: To get an MC number (interstate operating authority) in 2026, create an account at motus.dot.gov, verify your identity, apply for a USDOT number and operating authority, and pay FMCSA's $300 fee for each authority type. After FMCSA publishes your application there is a 10-day protest period. Your authority goes active once your insurance company files proof of coverage and your process agent files your BOC-3. Most new carriers are active in about 3 to 6 weeks.

Do you need an MC number?

You need an MC number if you haul regulated freight for pay across state lines (for-hire interstate), or if you arrange freight for others as a broker. You generally do not need one if you only haul your own goods (private carrier) or only operate within one state, though you may still need a USDOT number. See our guide to DOT number vs. MC number.

Step-by-step: how to get your MC number

1. Set up your business. Decide on your legal business name and entity (LLC, corporation or sole proprietor) and get an EIN from the IRS. Your legal name must match exactly everywhere you file.
2. Create your Motus account. Go to motus.dot.gov. Motus uses Login.gov, and FMCSA requires new registrants to pass an online identity check with a government-issued ID. Have your phone or a webcam ready.
3. Apply for a USDOT number and operating authority. Motus asks what you will haul, how you operate, your vehicles, and your company officials. Most new trucking companies select Motor Carrier of Property.
4. Pay the $300 FMCSA fee for each authority type you request. It is paid online and is not refundable, so check every answer first.
5. Wait for review and the 10-day protest period. FMCSA reviews your application, assigns your MC (docket) number, and publishes it. Anyone may protest within 10 days of publication.
6. Get insurance filed. Your insurance company files Form BMC-91 or BMC-91X with FMCSA. See insurance requirements for new authority.
7. Get your BOC-3 filed. A process agent company files it electronically for every state. See our BOC-3 guide.
8. Confirm you're active. Look up your USDOT number on SAFER. Don't haul interstate loads until your authority shows as active.

What does it cost?

FMCSA charges $300 per authority type. A USDOT number is free. Plan on a BOC-3 filing (usually under $100), UCR registration ($46 for 2026 and $55 for 2027 if you run 0 to 2 trucks), and your insurance down payment, which is usually the biggest cost. Full breakdown: how much it costs to get trucking authority.

How long does it take?

Expect roughly 3 to 6 weeks from application to active authority, depending on FMCSA review time and how fast your insurance and BOC-3 are filed. Details: how long it takes to get MC authority.

Frequently asked questions

Can someone else apply for my MC number?

Service providers can prepare and help with filings, but FMCSA requires identity verification in Motus, so plan to complete that step yourself.

Can I still mail a paper OP-1?

FMCSA now processes new registrations online in Motus and stopped accepting paper transactions in most cases. Use the OP-1 questions as a worksheet to prepare your answers.

Are MC numbers going away?

Not yet. FMCSA has deferred eliminating MC numbers to a later phase, so new carriers still receive one in 2026.
