DOT and MC Number Application
Combined application form for both your USDOT number and MC operating authority. We handle URS filing, insurance coordination, and BOC-3 designation.
Apply for DOT and MC NumberWhy Fleets Choose LBC Fleet for MC Number Applications
The MC number application itself isn't complicated. What trips most carriers up is what surrounds it — inconsistent business names across URS and insurance filings, BOC-3 process agent designation that gets missed, BMC-91X public liability filed at the wrong level for passenger seating, and a new entrant audit that follows 12 months later with no one ready for it.
We've been handling DOT and MC filings for fleets since 2015 — the same workflow that handled 3,000+ real DOT audits since 2015 is what makes sure your application data lines up the first time.
- URS intake + insurance coordination — names, addresses, and insurance data aligned before submission, not after a rejection.
- BMC-91X public liability sized correctly — especially for passenger carriers where seating capacity changes the coverage requirement.
- BOC-3 process agent designation — handled inside the 90-day window so authority isn't held up.
- Passenger vs. freight authority guidance — we map your routes, equipment, and bookings to confirm which authority you actually need.
- New entrant audit prep — the audit that follows 12 months after authority is granted is where most new carriers stumble. We prepare you for it from day one. See new entrant safety audit preparation.
What goes wrong without a filing partner
Most application delays aren't about the wrong forms — they're about data mismatches between forms. Legal entity name on the URS doesn't match the insurance certificate. Business address on the BOC-3 doesn't match what's on the MCS-150. Insurance limit on BMC-91X is set for freight but the carrier is moving passengers.
These are exactly the patterns we catch before submission. Your application goes in clean, authority is granted on schedule, and you start the new entrant period already audit-ready.
What is an MC number and who needs operating authority
An MC number is FMCSA's docket identifier for operating authority. If you carry passengers for hire across state lines, or carry federally regulated commodities for hire in interstate commerce, you need operating authority.
Private carriers may not need it. Some operations inside a federal commercial zone or hauling exempt commodities may not need it either. We confirm your status and coach next steps before you file — rejected applications cost weeks of delay.

MC number requirements: operating authority types
Pick the authority that matches your operation. Some businesses need more than one.
- Motor Carrier of Property (except household goods)
- Motor Carrier of Household Goods (moving companies)
- Motor Carrier of Passengers
- Broker of Property and Broker of Household Goods
- Freight Forwarder (property or household goods)
- U.S. based enterprise carrier of international cargo or household goods
- Mexico domiciled options use MX or OP-2 programs
Authority type sets your insurance filings and financial responsibility requirements under 49 CFR Part 387.
Insurance filingsCommon forms
- BMC-91/91X — public liability
- BMC-34 — cargo for household goods carriers
- BMC-84/85 — broker and freight forwarder bond or trust
- BOC-3 — process agent designation
Your insurer or bond/trust provider files these with FMCSA. We coordinate the timing and data so nothing gets rejected.
MC number requirements for passenger carriers
- For-hire interstate passenger operations require operating authority under 49 CFR 365
- Insurance minimums depend on seating capacity: $1.5M for 15 or fewer (including the driver); $5M for 16 or more, per 49 CFR 387.33
- Prearranged air, rail, or ship plus shuttle can be interstate even within one state. Some short airport shuttles within a 25-mile zone are exempt from authority
We map your vehicles, seating, routes, and bookings to confirm your status and coverage level. Getting this wrong on the BMC-91X is a common reason passenger applications get held up.
Interstate, intrastate, and multimodal
Interstate status can apply even if your vehicle stays inside one state. For freight, the test is the shipper's fixed and persistent intent as defined by 49 CFR 390.3. If a leg is part of a continuous interstate movement, it is interstate. For passengers, a prearranged trip that pairs air or rail with a shuttle can make the shuttle interstate. Walk-up curb rides are different.
Examples- Warehouse to store inside the same state, but the goods came from out of state. Interstate.
- Passenger books flight plus hotel shuttle in advance. Interstate.
- Passenger lands and hires a local ride on arrival with no prearrangement. Usually not interstate.
How to apply for an MC number and get granted
Before applying for authority, compare USDOT and MC number requirements for the operation.
- Decide structure. Your entity, name, and business address must be consistent across all filings.
- Start in URS. New applicants use FMCSA's Unified Registration System for USDOT and operating authority.
- Pay fees. $300 per authority, with separate fees for each type.
- File insurance and BOC-3. Your insurer files BMC-91/91X and others. Process agent files BOC-3. You typically have up to 90 days after publication to complete filings.
- Publication and protest. FMCSA publishes your application with a short protest period.
- Processing time. URS applications commonly take about 20–25 business days, longer if flagged for vetting.
We prepare your evidence pack and keep names, addresses, and insurance data aligned to avoid delays.

MC and DOT number — usually both
Most for-hire interstate operations need both a USDOT number AND MC operating authority. The USDOT number identifies your company in FMCSA's safety system; the MC number is your docket for operating authority. They're separate filings but typically applied for together.
If you're starting fresh, see our USDOT number guide for the safety-registration side of the picture. Our combined application form handles both filings in one workflow.
Already have a DOT number? Skip to apply for your MC number. Need both? The combined form covers both in one pass.

MC Number FAQ
Do MC numbers need to be painted or displayed on the vehicle?
No. Federal rules require your legal name or DBA and the USDOT number on both sides of the vehicle. MC number display is not required.
Who actually needs an MC number?
For-hire passenger carriers in interstate commerce. For-hire carriers moving federally regulated commodities in interstate commerce. Brokers and freight forwarders need their own authority. Private carriers and some exempt commodity carriers may not.
What types of operating authority exist?
Motor Carrier of Property, Motor Carrier of Household Goods, Motor Carrier of Passengers, Broker of Property, Broker of Household Goods, and Freight Forwarder. Special cases include U.S. based enterprise carriers of international cargo or household goods, and Mexico domiciled programs.
How long does it take to get authority?
URS applications commonly take about 20 to 25 business days. Your application is published and can be protested for a short window. You also have a 90 day clock for insurance and BOC-3 filings. Vetting can add time.
Does a multimodal trip inside one state count as interstate?
Often yes when the whole trip is prearranged, like air plus shuttle. Walk-up curb rides are different. Freight legs tied to out-of-state origin or destination are also often interstate.
What obligations start once I have authority?
New Entrant Safety Audit. Biennial MCS-150 updates. Annual UCR. If you qualify, IRP and IFTA. HVUT 2290 for heavy vehicles. Maintain insurance on file. Stay ready for compliance reviews.
