How do you get an MC number?
To get an MC number you register with FMCSA for a USDOT number, apply for for-hire operating authority (the MC number), file a BOC-3 process agent, and have your insurer file proof of at least $750,000 liability coverage for general freight. Authority typically goes active a few weeks after everything is on file.
Almost every owner-operator hauling freight for other companies across state lines needs their own operating authority. Here is the process in the order that saves the most time, and what each piece is for. Rules and fees change, so confirm current requirements on the FMCSA website before you file.
USDOT number vs MC number
| USDOT number | MC number (operating authority) | |
|---|---|---|
| What it is | Company identifier for safety records | Permission to haul regulated freight for hire |
| Who needs it | Most commercial vehicles over 10,000 lbs in interstate commerce | For-hire carriers hauling for others across state lines |
| Issued by | FMCSA | FMCSA |
If you are a for-hire hotshot, box truck or semi operator crossing state lines, plan on getting both.
The steps
- Set up your business. Form an LLC or corporation, get an EIN, and open a business bank account. Keeping trucking finances separate makes taxes and factoring easier.
- Register with FMCSA and get a USDOT number. This is done online through FMCSA's registration system.
- Apply for operating authority (MC). Choose the for-hire carrier authority type that matches what you haul.
- File a BOC-3. This designates a process agent in each state where you operate. Process agent companies file it for a small fee.
- Get insurance and have it filed. For-hire carriers hauling non-hazardous general freight are required to carry at least $750,000 in public liability coverage, and your insurer files the proof with FMCSA. Most brokers also want cargo coverage, commonly $100,000.
- Complete other registrations: UCR (Unified Carrier Registration), IFTA and IRP if you run a qualifying vehicle, and Form 2290 for heavy vehicles.
- Wait for authority to go active. Once filings are on record and the protest period has passed, your MC status turns active.
What to prepare for brokers
Brokers will ask for a carrier packet: your MC authority letter, W-9, certificate of insurance, and payment details (or a factoring notice of assignment). Have these ready as PDFs so you can onboard with new brokers in minutes.
Costs to budget for
- FMCSA operating authority application fee (about $300 at the time of writing)
- Insurance down payment and monthly premiums, usually the largest startup cost
- BOC-3, UCR, IFTA decals, IRP plates, and 2290 tax
- ELD device and load board subscription

After your authority goes active
New authorities face a new entrant safety period and a safety audit within about the first year. Keep driver qualification files, logs, and maintenance records in order from day one.
A dispatcher can take load searching, rate negotiation and broker paperwork off your plate once you are active. At Texas Solutions, dispatch is 5% of weekly gross for semis, 8% for hotshots and 10% for box trucks, OTR, with no flat rate. Get a free estimate.
Frequently asked questions
What is the difference between a USDOT number and an MC number?
A USDOT number identifies your company for safety and compliance records. An MC number is your for-hire operating authority, which lets you haul regulated freight for others across state lines. Most for-hire interstate carriers need both.
How much does an MC number cost?
FMCSA charges an application fee for operating authority, which has been about $300. You also pay for insurance, a BOC-3 filing, and other registrations, so check the current FMCSA fee before you apply.
How long does it take to get MC authority?
Timelines vary, but many carriers see authority go active roughly three to four weeks after applying, once insurance and BOC-3 filings are on record and the protest period has passed.
Do I need an MC number to work with a dispatcher?
Yes, if you haul for-hire freight across state lines under your own authority. A dispatch service books loads under your MC number, so you need your authority active before dispatch can start.
