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 |
|---|---|
| MCS-150 Not Updated | FMCSA requires this update every two years. 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: Update the MCS-150 Form
Submit an updated MCS-150 form online using your USDOT PIN through the FMCSA portal.
Step 2: Request a USDOT PIN (If Needed)
If you don’t have your PIN, you can request one here: Request USDOT PIN
Step 3: Address Safety Audit Issues
If your USDOT was revoked due to a failed safety audit, follow the corrective action instructions in the New Entrant Safety Assurance Program .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 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. |
| USDOT Inactive | Missing filings or safety issues. | Update MCS-150 or resolve safety audit findings. |
| Not Authorized to Haul Motor Vehicles | Incorrect operating classification. | Submit an updated MCS-150 with the correct cargo type selected. |
Preventing Future Deactivation
- Update your MCS-150 every two years.
- Ensure insurance coverage never lapses.
- Regularly check your status in FMCSA SAFER.
