Close Your USDOT Number: A Step-by-Step Guide

Closing a USDOT number involves canceling your registration with FMCSA, winding down active authorizations, and ensuring final obligations are resolved. This guide outlines a clear, practical process for deregistering in the United States, reducing ongoing costs, and avoiding compliance issues after operations end.

Prepare For Closure

Begin by taking a comprehensive inventory of all active registrations tied to the USDOT number. This includes operating authority (MC or FF numbers), insurance coverage, hazmat endorsements, motor carrier registrations, and any permits. Review current and upcoming liability, fuel tax, and payroll obligations. Gather essential documents such as the most recent FMCSA registration, insurance certificates, and any recent safety audits. Creating a closure checklist helps ensure nothing is overlooked during deregistration.

Verify Obligations And Resolve Outstanding Items

Before canceling, settle all financial and regulatory obligations. This includes paying fines, penalties, and any outstanding registration fees. If the company has drivers or equipment leased to others, confirm there are no pending lease or contractual obligations that would obligate you to maintain active status. Ensure all required safety programs, driver logs, and maintenance records are up to date. If hazmat or other special endorsements are active, consult FMCSA guidance on closing related authorizations to avoid residual compliance requirements.

Cancel Registration In The Unified Registration System (URS)

FMCSA’s Unified Registration System is the official channel to cancel registrations. Log in with the company’s credentials, select the USDOT registration, and choose the option to cancel or surrender the registration. You may need to provide a reason for closure and confirm that you have fulfilled all final regulatory obligations. After submitting, you should receive a confirmation number or notification from FMCSA. It is important to preserve this confirmation for your records.

Confirm Cancellation And Update Records

Verify that the cancellation is reflected in FMCSA systems, including SAFER and MCMIS records. Obtain written confirmation or an official cancellation notice. Update internal records to reflect the USDOT number as closed in accounting, insurance, and fleet management systems. Remove the USDOT number from any public-facing materials, such as websites and trucking profiles, to prevent unnecessary inquiries. Maintain a final safety and compliance file in case future inquiries arise about the closure.

Notify Stakeholders And Plan Final Transitions

Communicate the closure to key stakeholders, including customers, lenders, insurers, and employees. Provide a clear timeline for the end of operations and any outstanding service commitments. If the company intends to re-enter the market later, understand that a new registration may require a fresh application and review process. For customers with ongoing commitments, arrange orderly wind-downs, transfer arrangements, or referrals to other carriers as appropriate.

Post‑Closure Considerations

After deregistration, maintain a minimal archive of records as required by law. Most carriers should retain compliance documents for several years, including transportation bills, insurance policies, audits, and driver qualification files. If vehicles are sold or leased, update titles and registration records accordingly. Regularly monitor FMCSA communications for any post-closure notices that may require action, and keep contact information current in case of future regulatory inquiries.

Tips For A Smooth Deregistration

• Document Everything: Keep dated copies of cancellation confirmations and final settlement documents.
• Communicate Proactively: Notify customers early to minimize disruption and preserve trust.
• Consult Professionals: If uncertain, seek guidance from a transportation attorney or a compliance consultant.
• Preserve Records: Maintain a compliance archive beyond the closure period required by law.
