Often, companies need to have interstate Operating Authority (MC Number) in addition to a DOT number. Operating authority defines the type of operation you can run, and what cargo you may carry.
Let J. J. Keller help you set up your operating authority properly, so you don't risk getting placed out of service. Contact us at
When is a MC Number Needed?
Typically, a motor carrier number is needed when:
- A carrier transports passengers in interstate commerce (for a fee or other compensation either direct or indirect)
- 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)
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.
Who Does Not Need Authority?
- Private Carriers (who only transport their own cargo)
- For Hire Carriers who only transport exempt commodities that are not federally regulated
- Carriers who operate only in geographic territories that are exempt from authority rules
