Motor Carrier (MC) & USDOT numbers
If you’re an interstate, for-hire motor carrier of non-exempt property and passengers, in addition to a USDOT number you’re also required to have operating authority. FMCSA tracks authority through motor carrier (MC) numbers.
MC numbers define:
- The type of operation you’re allowed to run
- The cargo you’re authorized to transport
- Whether you can operate as a for-hire carrier
A USDOT number is the unique identifier for a carrier or driver and is used by the FMCSA to monitor safety compliance. Companies that operate commercial motor vehicles that transport cargo or passengers across state lines (interstate commerce) must have a unique number issued by the Federal Motor Carrier Safety Administration (FMCSA). Our compliance team will make the process of getting your DOT number — or updating an existing number — easier for you.

Choosing the Right Authority Matters
Applying for operating authority isn’t just a formality — it is a fundamental step in building a trucking business. Your operating authority determines what your business is legally allowed to do.
Without the correct authority in place, you may run into:
- A delay in approval, which would lead to a delay in beginning operations
- Additional application fees, as you may need to reapply
- Compliance issues, which could lead to expensive fees, audits, or even being placed out of service
By applying for the correct authority from day one, you can avoid costly rework, and put yourself and your company in the best position to get on the road sooner – and stay there.

USDOT/MC Number Service FAQs
Who needs an MC Number?
expand_moreexpand_lessTypically, a motor carrier number is needed when:
- A carrier transports passengers in interstate commerce (for either direct or indirect compensation)
- A carrier transports federally-regulated commodities that are either owned by others or arranging for their transport in interstate commerce (for a fee or other compensation)
- A freight forwarder is assembling, consolidating, or distributing shipments across state lines
- Household goods movers are carrying personal property across state lines
The FMCSA operating authority can be identified as an "MC", "FF" or "MX" number based on what authority is granted. It's possible that your business may need multiple operating authorities. Contact us and we’ll help you determine what’s needed. If you’re an interstate, for-hire motor carrier of non-exempt property and passengers, you’re also required to have a motor carrier (MC) number.
Who Does NOT Need Operating Authority?
expand_moreexpand_lessNot all carriers need the same level of authority. For example, some carriers are exempt from MC numbers, including:
- Private carriers transporting their own products, such as landscaping companies hauling their own equipment to job sites
- For-hire carriers transporting exempt commodities, such as specific agricultural and livestock products
- Carriers operating only within exempt commercial zones
Not sure where your company fits? You’re not alone. This is one of the most frequent scenarios we work with customers to solve.
