Trucking compliance goes far beyond managing proper paperwork, and there’s a lot more to it. One of the most important pieces of the compliance puzzle is the DOT (Department of Transportation) number. Issued by the Federal Motor Carrier Safety Administration (FMCSA), your USDOT number acts as a central identifier for your company’s safety performance, insurance status, and operating authority. Many truckers think getting a USDOT number is a one-time activity, but that’s not true. Obtaining the USDOT number is only the beginning, and maintaining its active status is what truly keeps your business moving.
An inactive or expired DOT number can halt operations, trigger penalties, and even impact your operating authority, often for avoidable reasons such as lapsed insurance or failing to complete biannual updates. Checking and understanding your DOT status ensures your company remains compliant, visible, and operational. It also helps you monitor safety ratings, identify potential violations, and avoid costly disruptions. Whether you’re new to the industry or a seasoned carrier, knowing how to verify the status of a DOT number—your own or someone else’s—serves an essential purpose.
In this guide, we’ll explain what DOT status means, how to check it, why it matters, and what to do if your USDOT number becomes inactive or out-of-service.
How to check your DOT number status?
Though the FMCSA may alert carriers when there’s an issue with their DOT number, relying on notifications alone isn’t always enough because you might miss out and learn only after facing a consequence or the other. Whether you’re checking your own company’s status or verifying another carrier before booking freight, knowing where and how to check DOT number status helps prevent delays, compliance headaches, and costly surprises.
1. Check your DOT status through the FMCSA website (SAFER system)
The fastest and most reliable way to check the status of your USDOT number is through the Federal Motor Carrier Safety Administration’s (FMCSA) online tool. Since DOT numbers and their status are public information, you don’t need a login or account to perform a lookup. All you need is either the USDOT number or the registered company name.
Start by accessing the FMCSA’s SAFER (Safety and Fitness Electronic Records) system. This official lookup tool provides a complete snapshot of a carrier’s compliance profile. Once you enter your USDOT number—or search by company name if the number is unknown—you’ll be able to review key details, including:
- Current DOT status (active, inactive, out-of-service, pending, etc.)
- Company name, address, and contact information
- MC number and operating authority (if applicable)
- Number of drivers and vehicles
- Types of cargo authorized for transport
- Inspection and crash history
- Safety ratings and performance indicators
- Any out-of-service orders or violations
If you’re searching by company name, keep in mind that multiple businesses may share similar names. Filtering by state or city makes it easier to identify the correct listing.
Once the results load, review the DOT status field to determine whether your registration is active and compliant, or whether you need to update information, renew filings, or resolve safety-related issues.
2. Verify your DOT status through the FMCSA support (ticket, chat, or phone)
If you prefer direct assistance or need clarification beyond what the FMCSA website provides, you can reach out to the FMCSA support team through multiple channels. These methods are especially useful if your DOT number is inactive, suspended, revoked, or showing conflicting information online. This way, you can be sure about the DOT status without spending too much time guessing.
Submit a support ticket
Use the FMCSA Help Portal to submit a request, provide the required details, and attach any supporting documents. After submitting, you’ll receive a tracking number so you can monitor the progress of your inquiry.
Use live chat
FMCSA’s live chat allows you to connect with an agent in real time for quicker verification and guidance on your DOT status or compliance issues.
Call customer service
You can also verify your USDOT status over the phone by calling FMCSA customer service at 800-832-5660 and speaking directly with a representative.
3. Use third-party DOT lookup tools
While the FMCSA offers the most accurate and current information on DOT status, several third-party websites also provide DOT number lookup tools. These can be convenient for quick checks or comparisons, but their data isn’t always updated in real time. If you use a third-party checker, always confirm the results through the official FMCSA systems to avoid acting on outdated or incorrect information. Once again, this would provide a double layer of confirmation, so you are sure about the accuracy of your findings.
4. Check your safety records for compliance issues
Your safety performance and compliance history can also signal when it’s time to verify your DOT number status. If you receive alerts or notifications from the FMCSA about violations, inspections, or paperwork issues, those could be early indicators that your DOT status may be at risk.
Regularly reviewing your safety records helps you stay ahead of potential problems. If your DOT number shows as inactive, out-of-service, or revoked, you may need to update company information, complete required filings, upload insurance, or resolve outstanding compliance items. Addressing these issues promptly ensures your business stays operational and avoids fines, delays, or legal complications.
What does DOT status mean?
Your DOT status reflects more than just whether your USDOT number is active or inactive. It represents a combination of factors, including registration standing, safety records, operational authority, and regulatory compliance monitored by the FMCSA. This includes details such as:
- USDOT registration details
- Safety and inspection history
- Compliance with drug and alcohol testing requirements
- Operating authority and insurance filings
- Any violations or out-of-service orders
Together, these elements determine whether your company meets federal safety and operational standards to legally run commercial vehicles.
Understanding your DOT status means taking a closer look at performance metrics—not just confirming that your number exists. Reviewing inspections, safety ratings, and compliance indicators helps ensure your business stays legal, safe, and competitive in the trucking industry.
Why is it important to monitor your DOT status?
Keeping track of your DOT status isn’t just a compliance box to check—it directly affects your ability to operate, haul freight, and maintain good standing in the industry. Neglecting it can create costly and avoidable problems.
For instance, a weak safety rating can trigger more frequent roadside inspections or audits, which may result in penalties, delays, or even temporary shutdowns. Likewise, failing to comply with drug and alcohol testing requirements can lead to violations being recorded in the FMCSA Clearinghouse and may result in disciplinary actions or restricted operating privileges.
By monitoring your DOT status routinely, you can catch issues early, address them before they escalate, and ensure smoother inspections.
How often should you check your USDOT Number status?
You should check your USDOT number status regularly. Most carriers benefit from reviewing their USDOT status monthly or at least quarterly. Compliance isn’t a one-time task—your status can change due to safety scores, MCS-150 updates, insurance filings, Clearinghouse violations, audits, or paperwork issues.
Performing regular DOT number checks helps you:
- Stay compliant: Prevent penalties, fines, and compliance violations from the FMCSA.
- Build credibility: Demonstrate reliability and professionalism to brokers, shippers, and customers.
- Maintain safety standards: Confirm your operations align with federal safety expectations.
- Control costs: Strong compliance and better CSA scores often translate to lower insurance premiums and reduced risk exposure.
How to check if a USDOT Number is still active?
The quickest way to verify whether a USDOT number is active is through the FMCSA’s SAFER system. Simply search by DOT number or company name to view the current status, which may show as active, inactive, revoked, or out-of-service. Making this check a part of your routine helps prevent unexpected compliance issues and keeps your business running smoothly.
What happens if your USDOT status is inactive?
An inactive USDOT status can immediately disrupt operations. When your number is not active, you cannot legally operate, haul freight, or participate in commercial transportation activities. This can lead to a variety of complications, including:
- Unexpected operational shutdowns
- Legal and financial penalties
- Delays in booking loads or renewing insurance
- Missed compliance updates or filing deadlines
Because an inactive status affects both compliance and business continuity, staying proactive is essential.
Why does a DOT number become inactive?
Your USDOT number can shift to inactive status for several operational or compliance-related reasons. Common triggers include:
- Missed biennial mcs-150 update: Not filing the required biennial update can automatically deactivate your USDOT number and may also result in FMCSA penalties.

- Insurance lapses: Allowing required motor carrier insurance to expire can cause the FMCSA to deactivate your USDOT number until coverage is reinstated.
- Failed or unresolved safety audit: New entrants who fail a safety audit or don’t submit a corrective action plan on time risk having their DOT number revoked or placed out of service.
- Paused or closed operations: Reporting an “out of business” or temporary pause through the MCS-150 form notifies the FMCSA to deactivate the number until operations resume.
- IFTA compliance issues: Failure to submit required IFTA fuel tax filings or payments can lead to enforcement actions that contribute to an inactive operational status.
How to reactivate a USDOT Number?
The most common way to reactivate an inactive USDOT number is by submitting the required MCS-150 biennial update. Start by checking your status in the FMCSA SAFER system to confirm whether your number is inactive or out of service and determine the reason for deactivation. In many cases, filing an updated MCS-150 (or MCS-150B for hazmat carriers) is enough to restore active status once processed, especially when a missed biennial filing is the reason.
If the deactivation resulted from an insurance lapse, failed safety audit, revoked new entrant authority, or paused operations, you may need to resolve those issues before submitting the update. Still, for most carriers, reactivation begins — and often ends — with filing the MCS-150 form.

Stay up to date with your DOT number status
Staying informed about your USDOT status isn’t just another administrative task — it’s a core part of running a compliant, efficient, and profitable trucking operation. Your DOT number reflects your company’s safety performance, insurance standing, operational authority, and regulatory compliance; all of which directly influence inspections, freight opportunities, and business continuity.
Whether you’re an owner-operator or managing a larger fleet, actively monitoring your DOT status helps you avoid shutdowns, delays, fines, and compliance surprises. Regular checks also protect your reputation with shippers, brokers, and insurance partners who rely on accurate status information before doing business.
As a truck driver or carrier, your USDOT number is more than a requirement — it’s a gateway to legal operation and competitive advantage. Staying up to date ensures you’re prepared for audits, renewals, MCS-150 deadlines, and Clearinghouse obligations. It also helps keep your drivers safe and your vehicles on the road.
