Getting FMCSA Operating Authority — MC Number Guide
FMCSA operating authority (MC number) is required for for-hire carriers transporting regulated commodities or passengers in interstate commerce. The process involves filing through FMCSA's URS, designating a process agent (BOC-3), filing minimum liability insurance, and waiting out a 10-day protest period.
What Is Operating Authority?
FMCSA operating authority — commonly identified by an "MC number" — is a type of registration required for for-hire motor carriers operating in interstate commerce. It is distinct from a USDOT number (which is for safety monitoring). Operating authority grants permission to transport passengers or regulated commodities for compensation across state lines.
Who Needs an MC Number?
You typically need operating authority if you: (1) are a for-hire carrier transporting regulated commodities (most freight) in interstate commerce; (2) transport passengers for compensation in interstate commerce; or (3) are a freight broker or freight forwarder arranging interstate shipments. Private carriers (moving their own goods), contract carriers meeting certain exemptions, and carriers moving only exempt agricultural commodities may not need authority. Requirements depend on the type of operation — check FMCSA's registration guidance for your specific situation.
The Application Process
Applications for operating authority are filed through FMCSA's Unified Registration System (URS). You must already have a USDOT number. The application requires: type of authority requested (household goods, non-household goods, passenger, etc.), legal business name, process agent designation (Form BOC-3), and insurance filing. After approval, there is a 10-day protest period during which existing carriers can object. If no protest is filed, operating authority is typically granted after the protest period.
Insurance Requirements
Before operating authority becomes active, carriers must file proof of liability insurance with FMCSA. Minimum required insurance levels vary by operation type: general freight carriers typically need $750,000 in liability coverage; household goods carriers $1,000,000; passenger carriers up to $5,000,000 depending on vehicle size; and hazmat carriers up to $5,000,000. Insurance must be filed by the insurer directly with FMCSA — carriers cannot submit proof themselves.
BOC-3 Process Agent Requirement
All applicants for operating authority must designate a process agent in each state where they operate, using Form BOC-3. Process agents accept legal papers on behalf of the carrier. BOC-3 filings are typically handled by service companies for a modest fee and must be on file with FMCSA before authority is granted.
UCR — Unified Carrier Registration
Beyond the USDOT number and MC number, interstate carriers must also register annually with the Unified Carrier Registration (UCR) program. UCR fees are based on fleet size and must be paid before January 1 of the operating year in participating states. Registration is done through the UCR portal. Operating without a current UCR registration can result in roadside enforcement action. It is a separate requirement from FMCSA registration and easy to miss when setting up a new operation — add it to the checklist alongside the BOC-3 and insurance filings.
Frequently Asked Questions
How long does it take to get operating authority?
After submitting a complete application with insurance and BOC-3 on file, the 10-day protest period must pass without objection. In practice, many carriers receive active authority within 3 to 4 weeks of a complete application, though timing can vary.
Can I haul freight under someone else's authority while getting my own?
Owner-operators frequently lease to a carrier and operate under that carrier's authority. If you are leased to a carrier, you operate under their MC number and USDOT number. You do not need your own authority while under lease — but you also cannot haul for other carriers or independently while under that lease without your own authority.
What is a freight broker bond and do I need one?
Freight brokers (not carriers) must maintain a $75,000 surety bond or trust fund as a financial responsibility requirement (49 CFR Part 387). Carriers with operating authority for freight transport have different insurance requirements — the broker bond applies to brokers arranging shipments, not to trucking operations.
