How to get an MC number in 2026, step by step, with the fees dated
Register your company with FMCSA online and pay $300 for operating authority, have your insurer file your liability coverage and a process agent file your BOC-3, wait out publication and the 10-day protest period, then confirm the authority shows active. Plan on three to five weeks, and file everything yourself on FMCSA's own site.
Most "how to get an MC number" pages are written by companies that want to file it for you. This one is written by a dispatch desk that only gets involved after your authority is active, so there is no reason to make the process sound harder than it is. Every step below links the official page and shows the date we checked the fee.
First, the 2026 twist: the MC number is being retired
FMCSA has been modernizing registration so new applicants file one unified application, and it is moving toward the USDOT number as the single identifier for carriers. Carriers registering now may see their operating authority tied to their USDOT number rather than receiving a separate MC number, while existing MC numbers stay valid. The steps below are the same in substance either way: what changes is the number on the paperwork, not what you must file. Check FMCSA's registration page for the current screens before you start.
Before you file: four decisions that save weeks
- The business entity. LLC, corporation or sole proprietor, decided and formed, with an EIN. Your registration name must match your formation documents exactly; mismatches stall insurance filings and broker setups for months.
- The operation type. For-hire carrier of property is the usual answer. Do not tick broker authority by accident, and do not tick household goods unless you mean it; each adds different requirements.
- The insurance agent. Get quotes from trucking-specialist agents before filing, because your insurer must file your coverage with FMCSA before the authority can be granted.
- The process agent. Pick a BOC-3 provider in advance; it is quick, but it is a separate company and a separate fee.

Step 1: Register online
Create a Login.gov identity, then complete FMCSA's registration with your company details, operation type, cargo, vehicles and drivers. The USDOT number usually issues at the end of the session. Choose for-hire interstate authority for property if that is what you will run.
Step 2: Pay the authority fee
The federal fee is $300 per authority type, as published October 2026. One truck hauling general freight typically needs one authority type. That is the entire government charge for the authority itself.

Your insurer files proof of your liability coverage directly with FMCSA; you cannot file it yourself. The federal floor for general freight is $750,000, but most brokers will want $1,000,000 before they tender, so quote at the level the market expects. Ask the agent for the date they submit the federal filing, in writing.
Step 4: Get your BOC-3 on record
The BOC-3 designates a process agent in each state to receive legal papers on your behalf. A blanket-agent company files it electronically, usually within days, for a fee they set. One filing covers the states.
Step 5: Publication and the protest period
FMCSA publishes the application, and a 10-day protest period follows. Protests against ordinary carriers are rare, but the clock still runs. Your insurance and BOC-3 must be on record by the deadline in FMCSA's letter, or the application is dismissed and you start over.
Step 6: Confirm you are active
Do not trust a feeling or an email from a stranger. Look yourself up in SAFER and FMCSA's Licensing & Insurance system: authority status should read active, with your insurance listed. That is what brokers will see.
The steps after active that nobody bundles in
- UCR registration at ucr.gov before you operate interstate.
- A drug and alcohol program before the first load if the truck needs a CDL; see the owner-operator testing requirements.
- IFTA and IRP if your truck is over 26,000 lbs or has three or more axles and crosses state lines.
- ELD and records set up for hours of service, with files kept audit-ready from day one.
- The new entrant safety audit, which FMCSA schedules within your first 12 months.

Mistakes that cost new carriers weeks
| Mistake | What it costs | The fix |
|---|---|---|
| Filing through a site styled to look official | Service fees on top of the $300, sometimes for nothing extra | File at fmcsa.dot.gov yourself |
| Name on registration differs from the LLC documents | Insurance filing and broker setups stall | Match the legal name exactly, suffix included |
| Insurance bound but never filed with FMCSA | Authority never activates | Ask the agent for the filing date in writing |
| Missing the filing deadline in FMCSA's letter | Application dismissed, start over | Put the deadline on your calendar the day you file |
| Paying unsolicited "compliance renewal" invoices | Money gone, nothing filed | Verify any notice on FMCSA's own site first |
What an MC number is not
It is not a USDOT number, though you will usually get both at once; the MC number explainer untangles them. It is not insurance, a guarantee of loads, or a license to broker freight. And it is not something any dispatcher, including us, can file or speed up for you. Check any carrier's status, including your own, with the DOT/MC lookup tool, and see the whole lookup topic at MC number lookup.
Filing is step one; loads are step two. The new authority dispatch page maps the first 180 days after activation. General information, not legal advice; FMCSA's current pages always win over this guide.
Straight answers
Q-01How do you get an MC number?
Register your company with FMCSA online, select for-hire interstate operating authority, and pay $300 per authority type, as published October 2026. Then your insurer files your liability coverage with FMCSA, a process agent files your BOC-3, and after the publication and 10-day protest period the authority is granted once those filings are on record.
Q-02What is an MC number in trucking?
The number that has historically identified a carrier's operating authority, FMCSA's permission to haul regulated freight for pay across state lines. Brokers check it before tendering loads. FMCSA is moving toward using the USDOT number as the single identifier, so newer carriers may see their authority tied to the USDOT number instead.
Q-03Do I need an MC number?
If you haul other people's regulated freight for pay across state lines, you need operating authority. If you haul only your own goods, only exempt commodities, or only inside one state, the federal authority requirement generally does not apply, though state rules and a USDOT number still may.
Q-04How long does it take to get an MC number?
Plan on roughly three to five weeks from filing to active in practice. The application is reviewed and published, a 10-day protest period runs, and the authority is granted once your insurance and BOC-3 filings are on record. Slow insurance filings are the most common delay.
Q-05Can I get an MC number without insurance?
You can file the application, but the authority will not be granted until your insurer's federal liability filing is on record, and FMCSA dismisses applications that do not complete their filings by the deadline in its letter. Line up a trucking-specialist agent before you file so the clock does not run out.
Q-06How much does it cost to get an MC number?
The federal fee is $300 per authority type, paid to FMCSA, as published October 2026. The bigger costs come after: insurance premiums, the BOC-3 filing fee set by your process agent, UCR, and a drug testing program if you run CDL trucks. Anyone quoting one bundled price is adding a service fee.
