If you tried to change your company address this summer, file a biennial update, or add an authority, you found out the hard way that FMCSA moved the furniture. The old Portal login does not go where it used to, and plenty of carriers got as far as the front door and could not get in.
Here is what changed, what did not change despite what you have read, and the one step stopping most people.
What Motus replaced
Motus is FMCSA's new registration system. It opened to supporting companies — BOC-3 blanket companies, insurance and surety filers, and the service providers who file for carriers — on December 8, 2025, then to all regulated entities on May 19, 2026.
It does not sit alongside the old systems. Per FMCSA's policy notice it replaces the Unified Registration System, the FMCSA Portal, the registration components of MCMIS, and the Licensing and Insurance system dating to 1994. Actions that used to be a form — OP-1, MCS-150, MCS-150B, MCS-150C, BOC-3 — become fields in an online flow. The one exception FMCSA named is Form OP-1(MX) for Mexico-domiciled carriers.
You can still mail a paper form until a rulemaking removes the references to them. But FMCSA's stated turnaround on that path is a minimum of eight business days for initial review, before any further vetting.
Your MC number did not disappear
You have probably seen confident writing saying MC numbers are dead and the USDOT Number is now the only federal identifier. Read it carefully before you act on it.
FMCSA did propose eliminating MC and FF docket numbers. Stakeholders pushed back — they wanted time to understand the change and adjust their own systems — and FMCSA responded by leaving three things out of the Phase II release: safety registration, the elimination of MC and FF numbers, and changes to how Form BOC-3 gets filed. The agency said it would take a measured approach and implement those in later releases.
So your USDOT Number is still the unique identifier, your MC number still exists, and nothing on your paperwork or your rate confirmations needs rewriting this week. Motus does add USDOT Number suffixes marking each registration you hold, but those are visible inside the system only — not in formal FMCSA correspondence, and not required for marking trucks.
Plan for the elimination eventually. Do not act as though it happened.
The claim step is where carriers get stuck
If you already have a USDOT Number, you do not register again. A company official creates a user profile, then claims the existing record, which pulls your data across to verify rather than retype.
That claim is the choke point. Two failure modes account for most of it:
- Email mismatch. You have to use the same Login.gov email that was the company official in the old FMCSA Portal. A different address — a personal one, or a new hire's — will not find your record.
- Wrong account type. Some motor carriers were inadvertently set up as Transportation Service Providers, which suppresses the claim option entirely. The fix is to close the TSP account from its account page, after which claiming should become available. FMCSA published guidance on this after carriers reported it.
Until the claim goes through, nothing else moves: no address change, no MCS-150 update, no new authority. Do it on a quiet Tuesday, not the week your insurance renews. If neither fix works, FMCSA's registration contact center takes tickets — expect to prove ownership with an IRS letter or incorporation documents.
Identity verification is now a real step
This is the part that surprises long-registered carriers. Identity proofing is not just for new applicants. FMCSA's notice says Motus verifies the identity of new applicants and of existing registrants when a user accesses the new system for the first time — on the order of 800,000 existing registrants.
Practically: you need a smartphone or tablet and a valid government-issued ID. You scan a QR code from Motus, photograph the ID, photograph your face, and return to finish. A separate business verification layer checks your legal name, principal place of business, ownership structure and company officials against outside records.
Budget fifteen minutes and have the ID in hand — not out in a truck.
None of that friction is accidental. FMCSA's notice is blunt about the reason: a significant increase in presumed fraudulent activity — identity theft, hijacked motor carrier accounts, numbers and PINs being sold, fake initial registrations, some of it likely by foreign actors. Verification is a tax on legitimate carriers to make impersonating one harder. Worth remembering when the QR code annoys you.
The biennial update pause is not a holiday
The rollout has been bumpy enough that FMCSA suspended enforcement of the biennial update, and the inactivation of USDOT Numbers, for registrants whose updates came due on or after June 1, 2026. As of mid-September 2026 that relief was still in place, until further notice, with FMCSA saying it would give warning before reinstating enforcement.
Read that precisely. The filing requirement did not go away. The consequence did, temporarily. A carrier who reads "paused" as "cancelled" is the one whose number deactivates the week the pause lifts.
Do the filing. Same discipline that keeps an IFTA quarter from turning into a penalty — see IFTA Basics — and the same reason you do not let an ELD sit on a revoked device list.
What to do this week
FMCSA's own pre-launch guidance is still the right checklist, and most of it is overdue rather than early:
- Claim your record, if you have not. Everything else waits on it.
- Check your process agent and insurance filings. A lapse there revokes authority, quietly.
- Save a copy of your current record to compare against what Motus shows. Carriers have reported fields coming across wrong, and you cannot spot that without a before.
- Prune your authorized users. Anyone who left or changed roles should not still have access to your registration.
That last one is the cheapest and the most skipped.
Where this lands operationally
Registration records, insurance certificates, authority letters and process agent filings share one property: nobody looks at them until one is missing and a load is sitting. Keeping them in one place with expiry dates attached is what turns a revocation into a reminder. In TFS Fleet that is the Documents side of the system.
The short version
Motus replaced four systems at once and is still settling. Your MC number is intact. Your identity gets verified whether you are new or twenty years in. The biennial update is paused on enforcement only. And until you claim your USDOT record you cannot change anything — so do that first, before you need it.
