How to Get MC Number Operating Authority: Step by Step

You have your truck. You have a load waiting. But you cannot legally haul freight for pay across state lines until you have your operating authority. Many truckers call it the MC number. Here is how it works, step by step, in plain words.

What operating authority is

Operating authority is FMCSA's permission for you to haul freight for pay across state lines. FMCSA is the Federal Motor Carrier Safety Administration, the agency that oversees trucking safety. Your USDOT number is your ID. Operating authority is your permission to work as a for-hire carrier. You need both.

For years, that permission came with a separate MC number. FMCSA has been moving to identify carriers by their USDOT number only, and it planned to phase out MC numbers by October 1, 2025. If you already have an MC number, it stays on file. But brokers may still say "MC number" out of habit. Rules and forms keep changing with FMCSA's new Motus system, so check the official FMCSA site for what your file will look like.

How to get an MC number: your operating authority steps

Here is the usual order. Every situation is different, so treat this as a map and not a promise.

• Step 1: Get your USDOT number. This comes first. Our new authority checklist shows how it fits with the rest.
• Step 2: Apply for operating authority. You apply through FMCSA's registration system, Motus. There is a filing fee. Check FMCSA's own site for the current fee.
• Step 3: Get your insurance filed. Your insurer files proof of coverage with FMCSA for you. It is usually done on a form called a BMC-91 or BMC-91X. Federal rules set minimum liability limits. For most general freight the minimum is $750,000, but the right amount depends on what you haul, so ask your agent.
• Step 4: File your BOC-3. This names a legal process agent in each state where you operate. Our article on the BOC-3 process agent explains it. It is required for for-hire carriers.
• Step 5: Wait out the protest period. After your application is public, there is a waiting period of about 21 days. Other companies can protest during that time. Industry sources say the whole process often takes about 4 to 6 weeks from start to finish. We cannot promise any timeline.
• Step 6: Your authority goes live. Once everything posts and the waiting period ends, FMCSA can make your authority active.

Why one missing piece keeps you parked

Your authority does not turn on with a single form. It goes live only after the filings land. If your BOC-3 is missing, or your insurance filing did not post, or the waiting period is still running, your authority is not active. Hauling before it is active can lead to fines and trouble with brokers. So one missing piece means you stay parked.

Mistakes to avoid

• Buying insurance before you know what is needed. Talk to your agent first so the filing matches what FMCSA needs.
• Forgetting the BOC-3.
• Using a look-alike website. Use only official FMCSA channels.
• Booking a load before you are active. Wait until your authority is active.
• Skipping the other filings. Later you may need UCR, IRP, IFTA and more. Our filing guide lists them.

Insurance and permits together

Common questions

Is an MC number the same as a USDOT number? No. The USDOT number is your ID. Operating authority, known for years as an MC number, is your permission to haul freight for pay across state lines.

How long does it take to get operating authority? Industry sources say it often takes about 4 to 6 weeks, including a waiting period of about 21 days. That is not a promise. FMCSA sets the timing.

Can I haul before my authority is active? No. Wait until your authority is active. Hauling without it can bring fines and hurt your business.
