A trucking company’s federal registration record should accurately describe the business that operates its commercial vehicles.
For a new motor carrier, that starts with determining whether a USDOT number is required and completing the appropriate application.
For an established carrier, the work continues through MCS-150 updates, operating authority verification, fleet changes, and accurate public records.
This guide provides a practical checklist for maintaining USDOT information in 2026.
Who Needs a USDOT Number?
A USDOT number generally identifies a company operating qualifying commercial motor vehicles in interstate commerce.
Federal registration criteria include certain vehicles or combinations weighing or rated at 10,001 pounds or more, specified passenger transportation, and applicable hazardous materials transportation.
Some states also require USDOT numbers for intrastate operations.
A USDOT number identifies the business, not each individual truck.
Step 1: Verify the Legal Business Entity
Confirm the company’s legal name, DBA, physical address, mailing address, and ownership structure.
Use consistent information across business formation records, federal registrations, insurance policies, and contracts.
A change in legal identity may require a different procedure from an ordinary contact-information update.
Do not apply for a duplicate USDOT number merely because the existing record contains an error.
Step 2: Identify the Required Registration
A new business may need a USDOT number, operating authority, or both.
The answer depends on whether it operates as a private carrier, for-hire carrier, passenger carrier, broker, or freight forwarder.
Certain businesses also need process-agent designations and federal insurance filings.
Determine the applicable registration category before submitting an application.
Step 3: Access FMCSA’s Motus System
FMCSA launched Motus on May 19, 2026, to modernize USDOT registration and related company transactions.
Visit MOTUS .
An authorized user creates an individual profile and completes the required The public’s one account for government. | Login.gov identity verification.
The company’s account should remain under the control of an authorized official.
Step 4: Claim an Existing USDOT Record
Existing registrants can use the applicable Motus process to claim their company records.
Review the imported legal name, address, and operational information.
Claiming a record does not issue a replacement USDOT number.
If the company encounters a claim or account-access problem, follow FMCSA’s official support instructions.
Step 5: Review the SAFER Company Snapshot
FMCSA’s SAFER system provides public information about motor carriers.
Review the legal name, USDOT number, registration status, available fleet details, and relevant safety information.
The public snapshot can help identify discrepancies.
It does not replace the company’s complete compliance files.
Step 6: Check Operating Authority Separately
A USDOT number and federal operating authority are different registrations.
Many interstate for-hire carriers require separate authority.
Some private and exempt operations do not.
The Motus transition does not mean all MC, FF, and MX docket identifiers have been discontinued.
Confirm the applicable authority status before conducting transportation that requires it.
Step 7: Verify Insurance and BOC-3 Filings
Applicable operating authority may require financial responsibility filings and a process-agent designation.
Insurance minimums depend on the operation, vehicle, and cargo.
Some qualifying for-hire property carriers are subject to a $750,000 federal minimum, while certain hazardous materials and passenger operations have different limits.
Check that required filings are effective.
An insurance quote alone does not establish that FMCSA has received and accepted the necessary filing.
Step 8: Review MCS-150 Information
The MCS-150 maintains company registration details, including:
- Legal name and DBA
- Business and mailing addresses
- Contact information
- Operating and cargo classifications
- Power units and drivers
- Vehicle mileage
Compare the reported information with current business records.
An accurate MCS-150 filing does not erase valid roadside inspection or crash data.
Step 9: Calculate the Normal Biennial Deadline
The final digit of the USDOT number determines the filing month.
| Final digit | Filing month |
| 1 | January |
| 2 | February |
| 3 | March |
| 4 | April |
| 5 | May |
| 6 | June |
| 7 | July |
| 8 | August |
| 9 | September |
| 0 | October |
The second-to-last digit determines whether filing occurs in odd- or even-numbered years.
The normal deadline is the last day of the assigned month.
Step 10: Check the Last Accepted Filing
An accepted qualifying MCS-150 or MCS-150C update within the 12 months preceding the scheduled biennial deadline can satisfy that update.
Verify the accepted filing date rather than relying solely on a submission confirmation.
An earlier qualifying update does not permanently reset the assigned schedule.
Step 11: Understand the 2026 Enforcement Suspension
FMCSA temporarily suspended enforcement of biennial updates and related USDOT-number inactivation for deadlines due on or after June 1, 2026.
The agency announced the suspension on September 10, 2026, during the Motus transition.
The underlying filing requirement remains.
This relief does not automatically reverse earlier inactivations or excuse unrelated regulatory obligations.
Step 12: Report Company Changes
FMCSA generally requires reportable registration changes to be updated within 30 days.
Examples may include changes in address, contact information, operations, or power-unit counts.
Certain ownership or legal-identity changes require additional documentation or a separate process.
Use the appropriate FMCSA transaction rather than assuming every change is a routine biennial update.
Step 13: Review Fleet Expansion
When adding commercial vehicles, review the reported fleet count and notify the insurer.
Verify vehicle markings, maintenance files, periodic inspection records, and driver qualification needs.
Determine whether the new vehicles affect IRP, IFTA, or UCR obligations.
Adding a truck does not automatically make it eligible for every interstate credential program.
Step 14: Confirm Vehicle Markings
Covered self-propelled commercial motor vehicles generally must display required carrier identification and the USDOT number on both sides.
Federal markings must contrast with the vehicle and be legible from 50 feet while stationary in daylight.
Federal rules do not impose a universal two-inch lettering-height requirement.
Check for additional state-specific marking requirements.
Step 15: Maintain Safety Records Separately
The MCS-150 is not a substitute for driver qualification files, hours-of-service records, drug and alcohol testing documentation, or vehicle maintenance records.
These obligations have separate federal requirements.
An accurate company registration does not guarantee full safety compliance.
Step 16: Identify the Actual Registration Problem
An inactive USDOT number, revoked operating authority, and out-of-service order are different regulatory conditions.
Determine the specific cause before filing anything.
For example, an insurance lapse may affect authority, while a safety out-of-service order requires compliance with its own restrictions.
A routine MCS-150 update cannot resolve every status problem.
Step 17: Verify UCR Separately
UCR is an annual registration and fee program for covered interstate transportation entities.
It is not completed through an MCS-150 update.
The 2027 UCR registration season opened October 1, 2026, and covered businesses must register and pay before January 1, 2027.
Check the applicable registration year and fee bracket independently.
Step 18: Distinguish Government Fees From Private Service Charges
FMCSA does not charge a federal government processing fee for a routine MCS-150 biennial update.
Other transactions, including certain operating authority applications, may have government fees.
Private compliance providers may charge separately for optional filing assistance.
Businesses should understand what each payment covers.
Step 19: Verify Filing Acceptance
After submitting a registration transaction, retain the confirmation and review the official company record.
A submitted application is not necessarily an accepted or effective registration.
FMCSA’s public Motus search and SAFER resources can help verify relevant information.
Allow for processing delays and follow up through official support channels when needed.
Step 20: Create an Ongoing Review Schedule
A practical review schedule should cover:
- Company identity and contact details
- MCS-150 filing status
- Operating authority and insurance
- Driver and vehicle records
- Fleet changes
- Applicable IRP and IFTA credentials
- Annual UCR registration
Assign responsibility for each item and maintain supporting records.
