Getting Your Own Operating Authority (MC/DOT)

A step-by-step walk through registering with FMCSA, filing insurance, and going active — without missing a requirement.

Key Facts

  • You register through FMCSA's Unified Registration System to get a USDOT number and operating authority (MC number).
  • Operating authority requires proof of insurance and a BOC-3 process-agent filing before it activates.
  • For-hire interstate carriers of general freight need active authority to run legally.
  • New entrants go through an FMCSA safety monitoring period after starting.

What 'authority' actually is

Operating authority (the MC number) is FMCSA's permission for you to haul regulated freight for hire across state lines. It's separate from your USDOT number, which is your carrier identifier. Most for-hire interstate owner-operators need both.

Before you apply

  • Decide your business structure (sole proprietor, LLC, etc.)
  • Have your insurance agent ready to file — authority won't activate without it
  • Know whether you also need IRP apportioned plates and IFTA
  • Budget for the application fee and ongoing compliance costs

Frequently Asked Questions

Do I need an MC number if I only haul within one state?
Purely intrastate carriers may not need federal operating authority, but state rules apply and you'll still likely need a USDOT number. Interstate for-hire freight requires FMCSA authority.
Can a service file all this for me?
Yes — many owner-operators use a compliance/filing service for the BOC-3 and registration paperwork. Just make sure you understand what's filed and keep copies.

Get your own operating authority

  1. Register with FMCSA: Apply through the Unified Registration System for a USDOT number and operating authority (MC number).
  2. Get insurance on file: Have your insurer submit the required liability (and cargo, if applicable) filings directly to FMCSA.
  3. File your BOC-3: Designate process agents in every state via a BOC-3 filing, usually handled by a filing service.
  4. Wait out the vetting period: FMCSA reviews the application; authority becomes active once insurance and BOC-3 are on record and the waiting period passes.
  5. Set up state credentials: Get IRP apportioned plates and an IFTA license/decals if you'll run interstate.
  6. Pass the new-entrant period: Operate safely through FMCSA's new-entrant safety monitoring to keep your authority.
