Description
Motor Carrier (MC) Number
A Motor Carrier (MC) number is a unique identifier issued by the Federal Motor Carrier Safety Administration (FMCSA) to commercial motor carriers. This number allows federal regulators to monitor and track trucking companies operating across state lines, or interstate.
An MC number confirms that a carrier has been granted operating authority. It is a key part of the FMCSA compliance system. It ensures trucking companies follow federal safety regulations and maintain proper insurance coverage.
Carriers that fail to obtain operating authority may face fines, penalties, and enforcement actions. For carriers transporting freight across state lines, MC number registration is an essential step to legally operate.

Frequently Asked Questions
What is a Motor Carrier (MC) Number?
A Motor Carrier (MC) number is a unique identifier issued by the FMCSA to commercial motor carriers. This number allows federal regulators to monitor and track trucking companies operating across state lines, or interstate freight transportation. An MC number confirms that a carrier has been granted federal operating authority, a critical component of the FMCSA compliance system.
Do I need both a USDOT Number and an MC Number?
If your trucks or commercial vehicles operate across state lines, you need an MC number in addition to a USDOT number. The USDOT number identifies your business for federal safety monitoring, while the MC number provides federal operating authority for interstate freight and passenger transport.
How long does it take to get an MC Number approved?
The timeline to get your MC number varies, but most carriers see approval within about 20–25 business days after submitting a complete application through the FMCSA’s Unified Registration System (URS). Incomplete paperwork or missing requirements can extend the review period, sometimes adding additional weeks.
Can I operate without an MC Number?
No. If your business hauls freight or transports passengers for hire across state lines (interstate commerce), you cannot legally operate without an MC number. Failing to secure and maintain your MC number registration can result in hefty fines, penalties, and enforcement actions.
