Interstate Carrier ResourcesDoes Reinstating Your MC Number Reset Your Authority Age?
Reviewed by Austin Park, founder of ICR Filings · Updated November 11, 2026
- Reinstatement keeps the same MC number. You are not issued a new one.
- FMCSA's public record keeps your authority history, including the suspension and the reinstatement, each with a date.
- FMCSA does not publish an authority age. Brokers and monitoring services calculate their own, and some count from the latest reinstatement.
- Keep your original grant letter. It is the simplest proof of how long you have held authority.
Many brokers will not load a carrier until its authority is six months or a year old. So when a suspension hits, the first worry is not the $80 fee. It is whether reinstating makes a five-year-old authority look five days old.
What does not change
Your MC number. Reinstatement is a request to make your existing operating authority active again, and FMCSA handles it against the docket number you already have. Your USDOT number, your company record, and your safety history stay attached to it.
FMCSA describes reinstatement as a request about the number you already hold:
“To reinstate your operating authority (MC, FF, or MX Docket Number), you will be required to: Comply to with the minimum financial responsibility requirements and Designation of Process Agent (BOC-3 Form) on file with FMCSA.”
FMCSA FAQ: How do I reinstate my operating authority?
What FMCSA's record shows
FMCSA's Licensing and Insurance (L&I) system keeps an authority history for each docket. The original grant stays in that history. A suspension is added as its own entry with a date, and so is the reinstatement. Anyone who opens the history can see that the authority was granted years ago, went inactive, and came back.
What FMCSA does not publish is a single number called authority age. There is no federal field that says how old your authority is.
Why brokers can still treat you as new
Age requirements are private rules. A broker, or the carrier monitoring service it subscribes to, decides how to calculate them. Some count from the original grant. Some count continuous active time, which a gap resets. We could not find any official rule or published standard for this, so nobody can promise you how a given broker will read your record.
What you can do about it
- Close the gap fast. A suspension of a few days reads very differently from one of several months. See how to reinstate MC authority.
- Ask before you assume. Email the brokers you run with and ask how they count authority age after a reinstatement.
- Keep your proof. Your original grant letter shows the first issue date. If you cannot find it, see how to get a copy of your authority letter.
- Check your own record. Look at your authority history in L&I so you know what a broker sees. How to check your MC number and status.
Reinstate, or start over with a new number?
A new application gives you an authority with no history at all, which is the outcome you were trying to avoid. It also costs FMCSA's $300 application fee and has to wait through the protest period before it is granted. Reinstatement costs $80 and keeps the number, the history, and the customers who already have you set up. Whether an old authority can still be reinstated is covered in suspended, revoked, or inactive.
Common questions
Do I get a new MC number when I reinstate?
No. A reinstatement request is for your existing MC, FF, or MX docket number. FMCSA's fee is $80.
Will my authority look brand new to brokers after one day inactive?
It depends on the broker and the monitoring service it uses. FMCSA's record shows your history with dates, but each company decides how it reads a gap. Ask the broker how it counts.
Does FMCSA have an official authority age?
No. FMCSA publishes status and history. Age rules such as six months of active authority are private business policies.
How do I prove how long I have had my authority?
Your original grant letter shows the date authority was first issued, and FMCSA's L&I system lists your authority history.
Would a new MC number be better than reinstating?
A new application starts with no history at all, costs $300, and waits through the protest period. Reinstatement costs $80 and keeps the number brokers already know.
