A deactivated USDOT number is recoverable — and for the most common cause, a missed biennial update, the fix is a single filing. The FMCSA's own guidance is direct: to reactivate a USDOT number, you submit the appropriate current MCS-150 series form. This guide walks the full recovery path, including the two harder variants — revoked MC authority and New Entrant revocation — that an MCS-150 alone does not cure.
Step 1: Confirm the Status and the Cause on SAFER
Before filing anything, look up the record in FMCSA's Motus public search by USDOT number or company name and read two fields: Operating Status and MCS-150 Form Date. What you see determines the recovery route (our SAFER field-by-field guide decodes the rest of the record):
- INACTIVE with a stale MCS-150 date — the classic missed-biennial deactivation under 49 CFR §390.19T. Cured by filing the overdue MCS-150.
- Record notes a New Entrant revocation — you skipped or failed the new entrant safety audit. Separate reapplication required.
- MC authority shows NOT AUTHORIZED or revoked — the operating-authority docket needs its own $80 reinstatement on top of the USDOT fix.
The deactivation timeline itself — how a missed filing turns into an INACTIVE status — is covered in our deactivation guide.
Step 2: Get Into Your FMCSA Motus Account
MCS-150 updates are made online in Motus (motus.dot.gov), which requires a Login.gov sign-in. FMCSA no longer uses a USDOT PIN; since Motus launched on May 14, 2026, you sign in with Login.gov and link your USDOT number to your account. If you have never set the account up, the setup sequence (see also the official MCS-150 form page) is:
- Create a free Login.gov account at login.gov if you do not already have one.
- Sign in at motus.dot.gov with the Login.gov account — Login.gov handles every sign-in.
- Link your USDOT number to the account — claim your existing USDOT record so you can file for it.
If identity verification fails or your USDOT number will not link, use FMCSA's help resources or contact FMCSA. Our Login.gov sign-in guide covers the steps.
Step 3: File the Current MCS-150
File the MCS-150 exactly as you would a normal biennial update — current address, fleet counts, driver counts, and prior-year mileage. The full field-by-field walkthrough is in our step-by-step filing guide. Two reactivation-specific cautions from the FMCSA:
- Use the current form version. The FMCSA does not accept expired versions of the MCS-150, MCS-150B, or MCS-150C, and warns that third-party sites circulate outdated copies.
- There is no separate “reactivation form” and no FMCSA fee. The MCS-150 series filing is itself the reactivation mechanism.
Step 4: Reinstate MC Authority If It Was Revoked for Another Reason
If your operating authority was revoked for another reason (for example, an insurance lapse), the MCS-150 alone does not restore it: revoked MC authority requires a separate reinstatement. Per the FMCSA's reinstatement guidance, you must:
- Reactivate the USDOT first.The FMCSA's systems will not accept a reinstatement request while the USDOT number is Inactive or Out of Service.
- Have insurance and BOC-3 current. Reinstatement requires minimum financial-responsibility filings and a process-agent designation (Form BOC-3) on file. Verify the designation before you pay the $80: it only counts if the process agent named on it is still FMCSA-registered, and if the authority comes back under a newMC docket number the old BOC-3 does not carry over — that docket needs its own designation. Only an FMCSA-registered process agent can file one; FastBOC3Filing covers all 50 states and D.C. for $75 one-time.
- Request reinstatement and pay the $80 fee— online via the FMCSA registration system (Motus), or on paper with Form MCSA-5889.
Note the exclusions: reinstatement is not available to carriers placed Out of Service as an “imminent hazard” or under a final unsatisfactory safety rating. And if the revocation came from the New Entrant program, the FMCSA has a dedicated “Reapply to Use a USDOT Number” path instead. For the authority-side paperwork, the Fast Reinstatement Filing team handles the end-to-end reinstatement workflow.
Filing Your MCS-150
MCS-150 filings are temporarily paused
FMCSA's new MOTUS system is causing issues with our filings - every order is currently severely delayed. Rather than take your order and make you wait, we're pausing new MCS-150 filings temporarily until processing returns to normal.
You can file your MCS-150 yourself for free in FMCSA’s Motus system at motus.dot.gov, signing in with Login.gov.
Step 5: Verify the Record and Notify Partners
FMCSA controls when the update shows in its records. Once it does, look up the record in FMCSA's Motus public search by USDOT number or company name, confirm the Operating Status reads ACTIVE and the MCS-150 Form Date shows your new submission, then notify brokers, load boards, your factoring company, and your insurer so they can re-run their checks.
Bottom line:a missed-biennial deactivation is cured by one current MCS-150 filed through Motus — free from the FMCSA, and FMCSA reactivates the USDOT number once FMCSA processes it. Authority revoked for another reason adds the $80 reinstatement; New Entrant revocation adds a reapplication. Diagnose on SAFER first, then file.
