How to Get Your MC and DOT Numbers: A New Trucker’s Guide

By Will Kremer, Truck Insurance Agent · Last updated June 28, 2026

Getting your own authority is the moment you stop driving for someone else and start running your own trucking business. The paperwork to get your MC and DOT numbers is not the hard part. The part that trips up most new truckers is the insurance, because the right filing is what actually switches your authority on. Here is how the whole process works in 2026, start to finish, and where to put your attention so you are not sitting idle with a number you cannot use yet.

USDOT number vs MC number: which do you actually need?

People use the two like they are the same thing, and they are not. A USDOT number is your safety and registration ID with FMCSA. It identifies your company, tracks your inspections and crash history, and is required for almost anyone running a commercial truck over 10,001 pounds in interstate commerce. An MC number, also called your operating authority, is the legal permission to haul regulated freight for hire across state lines. The USDOT number says who you are. The MC number says you are allowed to do the job.

Which ones you need comes down to whether you run interstate or intrastate.

• Interstate (crossing state lines): you need both a USDOT number and an MC number. This also covers freight whose pickup and delivery cross a state line even if you only drive one leg of it. If a load goes from Atlanta to Nashville and you only carry the Georgia portion, you are still in interstate commerce.
• Intrastate (entirely within one state): you generally do not need a federal MC number, but you usually still need a USDOT number, and about half the states require their own state-issued intrastate authority on top of it. Georgia is one of them. Check with your state DOT before you assume you are clear.

If you are not sure which side of the line you fall on, that is worth a five-minute conversation before you pay for anything. We field that call all the time, and getting it right up front saves you from buying authority you do not need or skipping one you do. You can read more on our owner-operator insurance page about how this plays out once you are actually running loads.

How to get your USDOT and MC numbers in MOTUS

FMCSA does all new registration through a system called MOTUS. You will set up a Login.gov account first, verify your identity, then file for your numbers from one dashboard. Here is the order it happens in.

• 1. Create a Login.gov account. If you used the old FMCSA Portal, use the same email. Login.gov uses two-factor sign-in, so have your phone handy.
• 2. Sign in to MOTUS. Go to the MOTUS homepage and sign in through the Login.gov button. It hands you back to MOTUS once you are in.
• 3. Accept the Rules of Behavior. A one-time agreement screen. Read it and continue.
• 4. Verify your identity. You photograph your face and a government ID with a phone or webcam. This step is new, and if you do not have a camera you can finish it in person at an FMCSA enrollment center.
• 5. Complete your profile. Your name pulls in from your verified ID. You add your address and phone.
• 6. Pick your workflow. Choose to start a new registration, and from there you request your USDOT number and apply for operating authority. Your USDOT number typically comes back within about 24 hours.

The USDOT number is the fast part. The MC authority is where the clock you need to watch actually starts.

The 21-day window: what has to happen before your authority is live

When you apply for MC operating authority, FMCSA publishes it and runs a vetting period of about 21 days before it becomes active. That window is not dead time. It is when two filings have to land, and if they do not, your authority just sits there pending. Here is the sequence most new carriers move through.

The BOC-3 is a process agent filing, a designation of who can accept legal documents for you in each state. A blanket service files it for around $25. The BMC-91 is your insurance company’s electronic proof to FMCSA that you carry the required liability limit. You cannot file the BMC-91 yourself. Your insurer does. That is exactly where new carriers lose a week or two, so it is worth understanding before you buy a policy.

The insurance that actually activates your authority

This is the section we wish every new trucker read first. The single biggest mistake we see is buying insurance from a company that will not file the BMC-91 and MCS-90 to your MC number. You can have your USDOT number, your $300 authority, your BOC-3, your truck, and your first load lined up, and still be stuck, because the filing that flips your authority to active never goes in.

Two forms do the work. The BMC-91 (or BMC-91X) is what your insurer files with FMCSA to prove your liability limit. The MCS-90 is an endorsement on your policy that guarantees the public can be paid if you cause a loss, even in a situation the policy might otherwise exclude. Both have to come from a carrier that writes new authorities and actually files for them. Not every market does.

The second mistake is the limit. The federal minimum for general freight is $750,000 in liability, but almost every broker and shipper worth hauling for requires $1,000,000, so that is what most new carriers actually buy. Hazmat and a few other categories run higher, from $1,000,000 up to $5,000,000. Insuring at $750,000 to save a little can quietly lock you out of the loads you got the authority for in the first place. There is more detail on this in our guide to how much insurance you need to activate your MC number.

Because this is what we do all day, we can usually bind coverage and send the filings the same day, sometimes within 30 minutes. We place new-authority trucking through carriers that write new ventures and file fast, including Progressive, GEICO, Cover Whale, Berkshire Hathaway and its National Indemnity company, and Canal, plus a set of specialist owner-operator and small-fleet programs for the cases the big names decline. The owner here ran her own trucks before she ever wrote a policy, so the goal is simple: get your filing in clean the first time so your 21 days are not wasted.

What it costs to get your authority

The government and filing fees are small and predictable. These are not your insurance premium, they are the cost of the numbers and filings themselves.

What the fee schedule does not show

The fees are the cheap part. The costs that catch new owner-operators off guard are the ones nobody puts on the checklist.

• Your insurance down payment. A first-year policy usually needs money up front, commonly $5,000 or more, before anything is bound. This is the single biggest check most new carriers write to get started.
• Plates and apportioned registration. IRP plates for a tractor are a real line item, separate from your authority.
• The slow first months. Plan for roughly six months of lighter loads while you build a track record, find your lanes, and earn better rates. Brand-new authorities do not get the best freight on day one.

First-year insurance for a new authority is higher than what an established operator pays, because the carrier has no history to price against. A new-authority owner-operator commonly runs a full package in the range of $12,000 to $30,000 for the first year depending on equipment and operation. Once you have a clean year behind you, that number usually comes down. See our new venture truck insurance page for how first-year pricing works.

What MOTUS changed in 2026

FMCSA retired its legacy registration portal and moved everything into MOTUS, a single system tied to Login.gov identity verification. The big practical change for a new trucker is that identity step, where you photograph your face and your ID before you can register. It is meant to cut down on fraud, and for most people it adds a few minutes, not a few days.

Worth knowing as of mid-2026: the rollout is still settling. Some numbers have come through slowly, a few have issued with incomplete or mismatched data, and FMCSA has been pushing fixes on a near-weekly basis. None of that should stop you, but build in a little buffer, and once your number is issued, check that your record reads correctly before you rely on it. If something looks off, MOTUS has a Contact FMCSA option that reaches a live agent during business hours.

Common mistakes that delay your authority

• Buying a policy that will not file. If your carrier will not put the BMC-91 and MCS-90 on your MC number, your authority never activates. Confirm the filing is included before you pay.
• Insuring at $750,000 when you need $1,000,000. The legal minimum and the working minimum are not the same number. Most brokers want a million.
• Waiting on the BOC-3 and insurance. Both need to be in during the 21-day window. File them early so activation is not held up at the finish line.
• Forgetting the cash you need beyond fees. The down payment, plates, and a few lean months are the real startup cost, not the $300.
• Getting authority you do not need, or skipping authority you do. Intrastate-only carriers often do not need an MC number, but interstate freight always does, even one leg of it.

Frequently asked questions

How long does it take to get an MC and DOT number?

Your USDOT number usually comes back within about 24 hours. The MC authority then runs through a vetting window of about 21 days before it activates, so plan on three to four weeks from start to a fully active MC number, assuming your insurance and BOC-3 are filed early.

How much does it cost to get MC and DOT numbers?

The USDOT number is free, MC operating authority is $300, the BOC-3 filing is around $25, and the UCR fee for one or two trucks is $46. Your insurance is separate and is by far the largest startup cost.

Do I need both a DOT number and an MC number?

If you run interstate for-hire, yes, you need both. If you run only within one state, you usually need a USDOT number but not a federal MC number, though about half the states require their own intrastate authority. When in doubt, confirm with your state DOT or give us a call.

Do I need an MC number for intrastate trucking?

Generally no. A federal MC number is for interstate operating authority. Intrastate carriers usually need a USDOT number and, in roughly 26 states, a separate state intrastate authority. The catch is that freight crossing a state line counts as interstate even if you only drive part of it.

What insurance do I need to activate my MC number?

You need primary liability at the required limit, $750,000 at the federal minimum and $1,000,000 in practice, with your insurer filing the BMC-91 to FMCSA and an MCS-90 endorsement on the policy. Without that filing, your authority stays inactive no matter what else you have done.

Ready to get your authority active?

The numbers are the easy part. The insurance filing is what gets you moving, and it is the one piece you do not want to get wrong on a 21-day clock. We write new authorities every week and can bind and file the same day.
