How to Apply for an MC Number Online (Step-by-Step Guide for New Carriers)
If you’re starting a trucking company, you’ve probably heard that you need both a USDOT Number and an MC Number. While the DOT Number identifies your business, the MC Number grants you operating authority to carry regulated goods or passengers across state lines.
For many new carriers, applying for an MC Number can feel complicated. In this guide, I’ll break down what an MC Number is, why you need one, and how you can apply for it online — sometimes even getting authority approved faster with the right help.
What Is an MC Number?
Issued by the Federal Motor Carrier Safety Administration (FMCSA).
Also called “Operating Authority.”
Required if you:
Transport regulated commodities across state lines.
Provide for-hire transport of passengers.
MC Numbers are tied to your DOT Number but represent a separate layer of authority.
Steps to Apply for an MC Number Online
Obtain your DOT Number first.
Apply for authority through the FMCSA’s Unified Registration System (URS).
Pay the federal application fee ($300 per authority).
Designate a process agent (BOC-3 filing).
Provide proof of insurance.
Wait for FMCSA approval (typically 21–25 days).
Common Mistakes That Delay MC Number Approval
Forgetting to file a BOC-3 form.
Submitting incorrect insurance documentation.
Choosing the wrong authority type (common, contract, broker).
Missing the UCR registration requirement.
