If you run a trucking company in the United States, you are probably already familiar with terms such as USDOT Number, MC Number, Biennial Update, and Operating Authority.

In May 2026, the way many FMCSA registration tasks are handled changed with the rollout of Motus: USDOT Registration System, the Federal Motor Carrier Safety Administration’s new registration platform.

FMCSA began transitioning registration functions away from several legacy systems on May 14, 2026, and Motus became available to all registrants on May 19, 2026. The platform is part of a broader modernization effort designed to centralize registration processes, improve status tracking, and strengthen fraud prevention.

But what does the new Motus FMCSA system actually mean for your trucking company? Let’s start with the basics.

What Is Motus FMCSA?

Motus is USDOT’s new registration system for FMCSA customers.

It is not a new permit, a new operating authority, or an additional identification number that trucking companies need to obtain. Instead, it is the platform where motor carriers, brokers, freight forwarders, and other regulated entities can complete and manage many of their FMCSA registration activities.

Through Motus, users can manage processes related to USDOT Numbers, Operating Authority, Biennial Updates, company information, and other registration actions.

You can access the official Motus portal to create or access your account and manage the registration processes available to your company.

It is also important to make sure you are using the legitimate website. FMCSA has warned about fraudulent emails and websites impersonating Motus. The agency also clarifies that Motus is not an acronym and should not be written in all capital letters.

What Is a USDOT Number and How Does It Relate to Motus?

A USDOT Number is an identifier used by FMCSA to maintain and monitor information related to a company’s operations and safety record, including information from inspections, audits, investigations, and compliance reviews.

Many companies operating commercial motor vehicles in interstate commerce are required to have a USDOT Number. Depending on what the business does, it may also need Operating Authority, traditionally identified by docket numbers using prefixes such as MC, MX, or FF.

Motus does not replace the USDOT Number or Operating Authority. What has changed is how companies apply for, update, and manage many of these registrations with FMCSA.

Why Did FMCSA Create Motus?

Before Motus, different registration activities were spread across systems such as the Unified Registration System (URS), FMCSA Portal, MCMIS, and Licensing & Insurance.

Motus is intended to create a more centralized registration experience. The system incorporates Login.gov, identity verification, real-time data validations, improved registration tracking, and a company account where users can manage multiple registration actions.

Area	Before Motus	With Motus
Access	Registration activities were spread across different FMCSA systems	Many registration activities are managed through one centralized platform
Security	Some electronic processes relied on the USDOT PIN	Access uses Login.gov and identity verification
Company information	Updates could require different FMCSA tools	Business and registration information can be managed through the company account
Tracking	Users could need multiple tools to follow a registration action	Motus provides more detailed status information and registration tracking
New registartions	Numbers followed the previous system structure	Newly issued USDOT and docket numbers are randomized, and new USDOT Numbers can display suffixes

What Can a Trucking Company Do in Motus?

Motus goes beyond applying for a USDOT Number for the first time.

A registrant can use the platform to apply for a new USDOT Number or Operating Authority, submit a Biennial Update, change company information such as its legal name or address, apply for additional registrations or authorities, and manage certain reinstatement, reapplication, activation, or inactivation processes.

Companies can also track the status of registration actions directly from their account.

In that sense, Motus functions as a central hub for many of the federal registration processes between a trucking company and FMCSA.

I Already Have a USDOT and MC Number. Do I Have to Start Over?

No.

If your trucking company already had a USDOT Number before Motus launched, your existing number does not change. Existing docket numbers also remain the same.

The Company Official can create the appropriate Motus account and “claim” the company’s existing USDOT record. FMCSA recommends using the same Login.gov email that the Company Official previously used for the FMCSA Portal.

Once the existing record is claimed, company information can be imported into Motus so it can be reviewed, updated, and certified.

Motus also removes the need for the traditional USDOT PIN when completing electronic registration transactions within the new system. Users access Motus through Login.gov and complete the required identity verification process.

Did Motus Eliminate MC Numbers?

This has been one of the most common sources of confusion since the platform launched.

No. MC Numbers did not disappear with Motus.

FMCSA has considered eventually making the USDOT Number the primary identifier and reducing or eliminating the use of certain docket numbers. However, that change is still under consideration and would require additional regulatory action.

For now, existing USDOT and docket numbers remain unchanged, and Motus continues to issue docket numbers using prefixes such as MC, MX, and FF.

One change for new registrations is that Motus assigns a unique docket number to each newly granted operating authority, making it easier to track the history and status of each authority separately.

What Are the New USDOT Number Suffixes?

Companies registering for the first time through Motus may notice letter suffixes displayed with their USDOT Number.

These letters help identify an entity type or a registration granted by FMCSA. For example, C identifies Property Carrier Operating Authority, while B identifies Broker Operating Authority. A company with multiple registrations may see more than one suffix associated with its USDOT Number.

These suffixes are displayed in Motus for identification purposes and are not a vehicle marking requirement. In other words, carriers do not need to repaint their trucks simply because a suffix appears next to their USDOT Number in Motus.

Motus Does Not Replace Every Requirement for Your Trucking Company

This is one of the most important things to understand.

Although Motus centralizes many activities related to FMCSA registration, it does not mean that every permit, tax, report, or compliance requirement for a trucking company is now handled through Motus.

Depending on how your company operates, you may still have responsibilities involving IRP, IFTA, UCR, Form 2290, state permits, weight-distance or highway-use taxes, oversize and overweight permits, safety requirements, the Drug & Alcohol Clearinghouse, and other state or federal requirements.

What applies to your business can depend on the type of operation, vehicles, routes, cargo, and states where you operate.

That means having access to Motus does not automatically mean your trucking company is up to date with every regulatory or administrative requirement.

At Personal Truck Services, we help trucking companies manage different permits, registrations, reports, and administrative processes based on their operations.

What Should Your Trucking Company Do Now?

If your company already has a USDOT Number, start by making sure you can access Motus through Login.gov and that the correct Company Official can claim or access the company record.

Next, review the information associated with the business. Check details such as the legal company name, address, contact information, registrations, and other information shown in the account.

It is also important to continue paying attention to your Biennial Update and other registration responsibilities. Moving to a new platform did not eliminate those requirements.

FMCSA provides an official Move into Motus guide with instructions and resources for both new registrants and companies that already had a USDOT Number before the transition.

A Note About Biennial Updates in 2026

As of September 2026, FMCSA has temporarily suspended the inactivation of USDOT Numbers for entities that have not completed the required Biennial Update since June 1 while the agency continues supporting the transition and stabilization of Motus.

This temporary measure does not mean that Biennial Updates are no longer required. Companies should still review and complete any required updates that apply to their registration.

Motus Is Only One Part of Managing a Trucking Company

Motus represents an important change in how FMCSA registration is managed, but it is still only one part of the administrative responsibilities that come with operating a trucking business.

Permits, state registrations, taxes, reports, and safety-related requirements may still need to be handled outside the platform.

At Personal Truck Services (PTS), we help truck drivers, owner-operators, and trucking companies with truck permits, registrations, taxes, accounting, and other administrative needs related to their operations.

While you focus on driving and running your business, our team can help you handle the paperwork.
