Operating Authority (MC Number) — How to Apply
General information for motor carriers · Not legal advice.
Operating authority — your MC number — is the FMCSA's permission to run as a for-hire carrier of regulated goods (or passengers) across state lines. It is different from your USDOT number, which identifies you for safety; many carriers need both.
Who Needs It
For-hire carriers of regulated commodities operating interstate, and for-hire passenger carriers. Private carriers (hauling their own goods) and certain exempt commodities generally do not. See also our guide to for hire tags and commercial plates.
The Application Steps
- Have your USDOT number in place.
- Apply for operating authority and pay the application fee.
- File your insurance (e.g., a BMC-91 for liability).
- File a BOC-3 designating process agents in every state.
- Clear the mandatory vetting / protest period, after which your authority activates.
Key Terms
- BOC-3: process-agent designation required before activation.
- BMC-91: proof of public liability insurance filed with the FMCSA.

What is a BOC-3 filing?
A BOC-3 designates a process agent in each state who can accept legal documents on your behalf. The FMCSA requires a BOC-3 on file before activating your operating authority.
