How to get your own authority (DOT and MC number), step by step

Checked October 2026

The short answer: getting your own authority is a filing process, not a test. You register with the federal motor carrier office, pay a $300 filing fee for operating authority, have your insurance company file proof of your policy, and file a BOC-3 form that names a legal contact in every state. The whole path usually takes about three to four weeks. The fees are the small part. The insurance is the real cost, and it is the step everything waits on.

First, the two numbers are different doors

A DOT number is an identity number. It says who you are so your safety record can be followed, and it is free. An MC number is operating authority — permission to carry other people's goods for hire across state lines. You need the DOT number first, and the MC number is the one that makes you a carrier. Our DOT number guide explains when each one is required, including the weight line that decides a lot of this for cargo vans.

The steps, in order

Step 1: Set up the business. Most drivers form an LLC and get an EIN from the IRS first, because the federal registration asks for the business, not just the man. The EIN is free.

Step 2: Register for the DOT number. Applications run through the FMCSA's registration system, called MOTUS, with a Login.gov account. The DOT number itself is free and usually comes back in about a day.

Step 3: Apply for operating authority. In the same system, you apply for the MC number and pay the $300 filing fee. Your application is then published and sits through a federal review window. You cannot haul under your own authority during this window, whatever anyone tells you.

Step 4: Buy insurance that can be filed. This is where most new carriers stall. Your authority does not switch on until an insurance company files proof of your policy with the FMCSA — the filing is called a BMC-91. A cheap policy from a company that will not make the filing is worthless paper. Brokers and companies also set their own practical bar: $1,000,000 in auto liability and $100,000 in cargo cover show up again and again in real carrier requirements. Budget for a serious down payment — carriers commonly put $5,000 or more down on a first-year policy.

Step 5: File the BOC-3. This form names a process agent — a legal contact who can receive court papers for you — in every state. Filing services do it for roughly $25 to $100, one time. It is a small form and your authority cannot activate without it.

Step 6: Register for UCR. The Unified Carrier Registration is a yearly fee for interstate carriers. For the smallest fleets it is a small fee — about $46 for 2026. It is separate from the FMCSA registration and easy to forget, so do it in the same week.

What it all costs, honestly

The government's part is a few hundred dollars: $300 for authority, a small BOC-3 fee, a small yearly UCR fee, and a free DOT number. The real money is the insurance — the down payment and the first months of a first-year policy at new-carrier prices. Services will offer to do the filings for you for a few hundred dollars more. The filings are simple enough that most drivers can do them, and no service can make the insurance cheaper or the calendar shorter.

Before you file, know the alternative

Your own authority is one of three lawful paths. Leasing on to a carrier means running under their authority and their numbers, with less paperwork and less freedom. Local courier work inside your state may need neither number, depending on the work. Our lease-on guide walks through the honest comparison. If your own authority is the right path, file in the order above — and while the window runs, build your list of companies.
