How to Activate Your MC Number (Operating Authority)

Quick answer: How long does it take for an MC number to become active?

A new MC number usually becomes active about 3 to 4 weeks after FMCSA grants it. Before it activates, your insurer must file proof of liability coverage (BMC-91 or BMC-91X), a process agent must file your BOC-3, and the 10-day protest period must pass. You cannot haul interstate for-hire freight until the authority shows active.

Step by step

  1. Get a USDOT number and apply for authority

    Register through FMCSA's online registration system and request for-hire motor carrier operating authority. Pay the $300 fee per authority type.

  2. Have your insurer file BMC-91 or BMC-91X

    Your insurance company files proof of at least the federal minimum liability coverage electronically with FMCSA. You can't file it yourself.

  3. Have a process agent file your BOC-3

    A blanket process-agent company files your BOC-3 electronically, naming an agent in every state. It's usually a one-time fee.

  4. Wait out the protest period

    After FMCSA publishes your application, anyone has 10 days to protest it. Most new carrier applications get no protest.

  5. Confirm the authority shows active

    Search your USDOT or MC number in FMCSA's Licensing & Insurance system. Only haul for-hire interstate loads once the authority status says active.

FAQ

Why is my MC number still pending?

Usually because FMCSA hasn't received your insurance filing (BMC-91/91X) or your BOC-3, or the 10-day protest period hasn't ended. Check your record in FMCSA's Licensing & Insurance system to see which item is missing.

Can I haul loads while my authority is pending?

Not as an interstate for-hire carrier under your own authority. Until it shows active you can drive under another carrier's authority, for example by leasing on to a carrier.

Are MC numbers going away?

FMCSA has announced plans to make the USDOT number the single identifier for carriers and retire MC numbers. Check FMCSA's registration pages for the current status before you apply.
