Introduction
If you're a carrier operating in the U.S., keeping your USDOT and MC numbers active and in good standing with the Federal Motor Carrier Safety Administration (FMCSA) is critical. If either number becomes inactive or not authorized, it can prevent you from booking or moving loads on Super Dispatch.
This guide explains why USDOT or MC numbers become inactive, how to check your current status, and what steps you need to take to reactivate your operating authority.
How to Check Your USDOT and MC Status
Before taking action, confirm your current status directly with FMCSA.
Why a USDOT Number Might Be Inactive
A USDOT number can become inactive for several reasons. The table below outlines the most common causes and what they mean.
| Reason | What It Means |
|---|---|
| Biennial Update Not Filed | FMCSA requires a registration update every two years through MOTUS. Missing it can deactivate your USDOT. |
| New Entrant Safety Audit Failure | Failure to pass the audit can result in revocation. |
| Voluntary Deactivation | The carrier requested removal from FMCSA records. |
| Regulatory or Safety Violations | Serious compliance or safety issues can trigger deactivation. |
How to Reactivate a USDOT Number
If your USDOT number is inactive, follow the steps below to bring it back into good standing.
Step 1: Log Into FMCSA MOTUS
Sign in to the FMCSA MOTUS portal using your Login.gov credentials and open your carrier record.
Step 2: File Your Biennial Registration Update
Within your carrier record, complete and submit your biennial registration update (MCS-150). Make sure your operating information is current and accurate before submitting.
Step 3: Address Safety Audit Issues (If Applicable)
If your USDOT was revoked due to a failed safety audit, follow the corrective action instructions in the New Entrant Safety Assurance Program.
Why an MC Number Might Show "Not Authorized"
An MC number can lose authorization even if the USDOT is active. The table below explains the most common causes.
| Issue | What Needs to Be Fixed |
|---|---|
| Insurance Lapse | Insurance provider must refile BMC-91 or BMC-91X with FMCSA. |
| Missing BOC-3 | A BOC-3 must be filed through a registered process agent. |
| Inactive USDOT | MC authority cannot be reinstated until USDOT is active. |
| Unpaid Fees or Violations | Outstanding issues must be resolved before reinstatement. |
How to Reactivate an MC Number
To reinstate your MC operating authority, complete the steps below in order.
| Step | Action Required |
|---|---|
| 1 | Confirm your USDOT number is active. |
| 2 | Have your insurance provider submit updated BMC-91 or BMC-91X filings. |
| 3 | File a BOC-3 through a registered process agent. |
| 4 | Submit a reinstatement request through the FMCSA MOTUS portal. |
| 5 | Pay the $80 FMCSA reinstatement fee. |
Common Decline Reasons and How to Fix Them
If your verification or reactivation request was declined, it's usually due to one of the issues below.
| Decline Reason | What It Means | How to Fix It |
|---|---|---|
| MC Not Authorized | Operating authority is not active. | Update insurance, file BOC-3, and submit reinstatement through MOTUS. |
| USDOT Inactive | Missing filings or safety issues. | File your biennial update through MOTUS or resolve safety audit findings. |
| Not Authorized to Haul Motor Vehicles | Incorrect operating classification. | Update your cargo classification through the FMCSA MOTUS portal with the correct cargo type selected. |
Preventing Future Deactivation
- File your biennial registration update every two years through FMCSA MOTUS.
- Ensure insurance coverage never lapses.
