USDOT Number Reactivation Checklist (Free Printable)

Step 1 — Diagnose from your FMCSA record

Look yourself up on SAFER (safer.fmcsa.dot.gov, Company Snapshot) and in the FMCSA Licensing & Insurance (L&I) system. Tick what you see.

• USDOT status "Inactive" and the MCS-150 date is more than two years old → deactivated for a missed biennial update. Fix: Path A below.
• Operating authority "Inactive" / "Revoked" with a reason such as involuntary revocation for lack of insurance or BOC-3 → authority was revoked. Fix: Path B (and Path A if the USDOT is also inactive).
• "Out of service" order (failed new-entrant audit, unsatisfactory rating, or imminent-hazard order) → you need a corrective action plan or rating upgrade request, not a simple reactivation. Talk to your FMCSA Division Office.
• "Not authorized" for a carrier that never applied for authority → you may only need authority if you are for-hire interstate; private carriers operate on the USDOT number alone.
• Note the exact status text, the date it changed, and any reason code: ____________________

Path A — Reactivate after a missed biennial update

1. Gather the full MCS-150 data set — use the MCS-150 worksheet so you are not hunting for vehicle and mileage counts mid-form.
2. Log in to the FMCSA Registration system (Login.gov + your USDOT PIN). If you have no PIN, request one first — it is mailed to the address on file, so correct the address by paper MCS-150 if that address is stale.
3. File the MCS-150 choosing the reactivation / biennial update reason. Confirm all counts, then certify.
4. Save the confirmation. Reactivation of the USDOT number is normally reflected within a few business days; recheck SAFER.
5. If you also let UCR lapse for the current year, register now — an active USDOT number with an unpaid UCR is the next roadside citation.

Path B — Reinstate revoked operating authority (MC number)

Applies to for-hire interstate carriers (and brokers/forwarders) whose authority was involuntarily revoked, most often because an insurance filing was cancelled or a BOC-3 was withdrawn.

1. Fix the underlying cause first: bind liability insurance at the required level (for general-freight for-hire property carriers this is commonly a $750,000 minimum; higher for hazmat and certain cargo — confirm with 49 CFR 387) and have the insurer make the electronic filing (BMC-91 / BMC-91X) to FMCSA. Cargo insurance filings (BMC-34) apply to household-goods carriers.
2. Confirm a BOC-3 (designation of process agents) is on file; if it was withdrawn, have a process-agent company refile it.
3. Submit the reinstatement request through the FMCSA Registration system and pay the reinstatement fee. If the revocation is old, FMCSA may require a new application instead — the system will tell you.
4. Check the L&I record until the authority shows Active and the insurance shows on file. Do not dispatch for-hire interstate loads until it does.
5. If the authority was revoked for a failed new-entrant audit or an unsatisfactory safety rating, complete the corrective action plan with your Division Office before applying.

First-time registration — getting a new USDOT number

• Register through the FMCSA Registration system (Unified Registration System) with Login.gov; the application asks for the same information as the MCS-150.
• For-hire interstate carriers: apply for operating authority at the same time (the application fee is per authority type); expect a 21-day protest period after the notice is published before the authority can become active.
• Arrange insurance filings and BOC-3 as in Path B — authority is not granted without both.
• Register for UCR, set up your drug-and-alcohol testing program and Clearinghouse account (CDL drivers), and, for interstate vehicles over 26,000 lb, IRP plates and an IFTA licence.
• Expect the New Entrant safety audit within the first 12 months — build the compliance files from day one (see the compliance binder index).
