FMCSA Motus: the new registration system, explained

Motus is the FMCSA's registration system. It replaced the Unified Registration System during 2026, and it is now where you apply for a USDOT number and operating authority, and where you update your details. The requirements did not change — the front door did.

What is Motus?

The FMCSA's registration platform, at motus.dot.gov. It handles new applications for USDOT numbers and operating authority, and the updates you make to your record afterwards. It replaces the Unified Registration System, generally called URS.

When did it arrive?

In phases. Supporting companies — process agents, insurers and the other parties who file on carriers' behalf — moved first, in December 2025. It opened to carriers, brokers and freight forwarders in May 2026.

That order matters more than it sounds. The people who file your BOC-3 and your insurance had to be operating in the new system before you could apply through it.

What actually changed for me?

The main practical change is getting in. New applicants create an identity-verified login before they can apply — a document check rather than just an email address and a password. Set that up before you plan to do anything else, because nothing can start until it is done.

Beyond that, you are doing the same things in a different interface: applying, paying the fee, updating your record.

What did not change?

Most of it, which is the part people miss. The $300 per authority application fee is the same. Proof of insurance still has to be filed by your insurer. The BOC-3 requirement is unchanged, and still has to come from a process agent rather than from you. Your MCS-150 obligation is unchanged.

UCR is not affected at all — it is administered by the states through the UCR Plan, not by the FMCSA registration system.

Do I have to migrate right now?

No. There is no separate migration task sitting in your inbox. You will encounter Motus the next time you need the FMCSA for something — a new application, a change to your authority, an MCS-150 update.

If someone contacts you claiming you must pay them to “migrate your registration to Motus” before a deadline, that is not a thing. Registration changes are exactly the moments when unsolicited offers multiply.

Is this why I did not get an MC number?

Related, but a separate change. The FMCSA stopped issuing new MC, FF and MX docket numbers on 1 October 2025, and your USDOT number is now the identifier. That is covered in there is no MC number any more.

Where does that leave my BOC-3?

Exactly where it was. Designations already on record stay on record, and new ones are filed by your process agent as before. What changed is the system your agent files through and the verification they have to pass to do it — which is their problem rather than yours.

More on that in what a process agent does.

Whoever files for you, verify your own status directly with the FMCSA. We are not the system of record and neither is any other filing service — every carrier should be able to confirm their own filings rather than take a vendor's word for it.
