How to Deactivate a USDOT Number?
Deactivating a USDOT number isn't complicated when you understand the proper procedure. The process centers on one specific form, the MCS-150 and requires you to select "Out of Business Notification" as your filing reason.
What matters most is following the FMCSA's established protocol precisely and maintaining documentation that proves you completed each step correctly.
Understanding What You're Actually Deactivating
Before you begin, recognize that your USDOT number and your operating authority (MC/MX/FF numbers) represent separate registrations with FMCSA. This distinction shapes how you approach deactivation.
Most carriers fall into one of three scenarios:
- Ceasing all operations under your USDOT number: File Form MCS-150 with "Out of Business Notification" checked.
- Suspending operations and revoking operating authority: Submit Form OCE-46 for voluntary revocation of authority, then handle your USDOT deactivation separately through MCS-150.
- Continuing business operations that don't require operating authority: Update your USDOT record using MCS-150 to reflect your current operational status without selecting "Out of Business."
Each path requires deliberate action. FMCSA doesn't recognize silence or inactivity as valid methods for deactivation.
The Step-by-Step Deactivation Process
Verify Your Current Registration Status
Start by pulling your current record from the FMCSA SAFER Company Snapshot. This free lookup tool lets you search by USDOT number, MC/MX number, or company name.
Document these details:
- Your complete legal business name and address
- Any operating authority identifiers connected to your account
- Current status of your USDOT number
Save a PDF or screenshot for your records. This baseline documentation becomes essential if questions arise later about your deactivation timeline.
Complete Form MCS-150 Correctly
The MCS-150 serves as your official notification to FMCSA. When filing for deactivation, complete items 1-16 and 30-31 on the form. Hazmat carriers must use Form MCS-150B instead.
Gather this information before you start:
- USDOT number
- Legal business name and EIN
- Complete physical address and contact information
- Government-issued driver's license copy for the person signing the certification
FMCSA requires the signer's ID as part of complete submission. Submissions without this documentation will be returned as incomplete, delaying your deactivation.
Submit Through the Fastest Channel
DOT Compliance Support recommends the online platform for registration updates rather than mailing paper forms. Online submissions through the portal are typically processed in approximately 1-2 weeks, while mailed forms face delays due to processing backlogs.
When you submit electronically, you'll receive a confirmation number via email. This confirmation serves as proof of filing and establishes your submission date.
Documentation to retain:
- Final signed version of your submitted form
- Email confirmation with your ticket or case number
- Follow-up SAFER snapshot showing updated status
Address Operating Authority Separately If Applicable
If you hold operating authority (MC, MX, or FF numbers), determine whether you want to formally revoke that authority. Voluntary revocation requires Form OCE-46, which must be notarized or signed in the presence of an FMCSA staff member.
Form OCE-46 handles operating authority revocation, but you still must complete the MCS-150 deactivation step for your USDOT number. These are parallel processes, not substitutes for each other.
Maintaining Compliance Through the Transition
Deactivating your USDOT number doesn't eliminate your responsibility to align all related registrations with your actual operational status.
Biennial Update Requirements
FMCSA requires biennial updates every two years for all USDOT holders, even companies that have ceased interstate operations or closed entirely unless you properly notify FMCSA of your closure. Failure to file triggers civil penalties of up to $1,000 per day with a maximum of $10,000, plus potential USDOT deactivation.
This is precisely why proactive deactivation matters. Filing "Out of Business" removes you from biennial update obligations and eliminates ongoing penalty exposure.
UCR Registration Considerations
If your operations previously required Unified Carrier Registration, verify whether you need to file for the current registration year before deactivating. UCR registration runs on a calendar-year cycle with fees due before January 1 of each registration year. Carriers who cease operations mid-year should confirm their UCR obligations are current to avoid compliance gaps.
Timeline and Verification
Most deactivation requests process within 8 days when submitted through FMCSA's online portal. After this period, verify your status changed by checking your SAFER Company Snapshot again. Your record should reflect "Inactive" status for your USDOT number.
If your snapshot still shows active status after two weeks, contact FMCSA through their Ask FMCSA portal with your confirmation number to check on processing status.
Why Professional Support Makes Sense
Deactivation represents the final compliance action for many carriers, but it's not the only administrative task involved in winding down operations. Between final UCR filings, operating authority decisions, and documentation requirements, the closeout process demands attention to regulatory detail.
DOT Compliance Support handles these registration requirements with a focus on keeping your compliance obligations clear and manageable. When you're ready to close one chapter and move to the next, we ensure the regulatory paperwork doesn't slow you down.
FAQs
Can you deactivate a USDOT number online?
Yes. FMCSA encourages online submission through the FMCSA Portal for faster processing compared to mailed paper forms. You'll upload your completed and signed MCS-150 form along with the required ID documentation through the portal system.
What form do you use to deactivate your USDOT number?
Form MCS-150, with "Out of Business" selected in the reason-for-filing section. Hazmat carriers use Form MCS-150B instead.
Do you need to do anything special with operating authority?
Operating authority and USDOT numbers are separate registrations. If you want to revoke operating authority, submit Form OCE-46 (notarized) in addition to filing your MCS-150 for USDOT deactivation. Both forms are required to fully close out both types of registration.
