The MCS-150 is one of the primary tools for maintaining a company’s federal USDOT registration information.
A properly completed update helps FMCSA maintain accurate records of the company’s identity, operations, vehicles, drivers, and mileage.
For motor carriers and other USDOT registrants, filing involves more than entering information into a form.
The company must confirm the correct filing requirement, review its existing record, use the appropriate FMCSA system, and verify that the update was accepted.
What Is the MCS-150?
The MCS-150 is the Motor Carrier Identification Report.
It is commonly used to complete the federal biennial update and report changes to an existing USDOT registration.
It is not a separate annual renewal of the USDOT number itself.
It also does not replace operating authority or UCR registration.
Step 1: Confirm the USDOT Number
Locate the USDOT number assigned to the legal business.
Check the official FMCSA registration record.
Verify that the legal name and number match the company.
Do not apply for a new number simply because an existing record requires correction.
Step 2: Determine Why You Are Filing
Common reasons include a scheduled biennial update, a change in company information, a change in operations, or an applicable status transaction.
The appropriate procedure depends on the requested action.
A legal entity change may require more than a routine information update.
Step 3: Calculate the Normal Biennial Deadline
The final USDOT digit identifies the month.
| Final digit | 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 identifies the year.
Odd digits correspond to odd-numbered years.
Even digits correspond to even-numbered years.
The normal deadline is the final day of the assigned month.
Step 4: Review the Last Accepted Filing
Check whether the company completed an MCS-150 or qualifying related update recently.
FMCSA counts a qualifying update completed within the 12 months before the scheduled biennial deadline as satisfying that update.
Confirm the accepted filing date.
A prior submission that was rejected should not be treated as an accepted update.
Step 5: Determine Whether Temporary Relief Applies
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 obligation remains.
The company should follow current FMCSA instructions and monitor future guidance.
Step 6: Gather Company Information
Before starting, collect the legal business name, DBA, physical address, mailing address, telephone number, email, USDOT number, and applicable business identifiers.
Review operating classifications and cargo categories.
Gather accurate power-unit, driver, and mileage information.
Some transactions may require supporting documentation.
Step 7: Review Power Units and Mileage
Compare the company’s reported fleet with its actual records.
Confirm the appropriate vehicle and driver counts.
Use accurate mileage information for the applicable reporting period.
FMCSA uses some of this information in safety measurement calculations.
Do not enter unsupported figures to influence a safety score.
Step 8: Access the Official Motus System
FMCSA launched Motus on May 19, 2026.
Visit MOTUS .
Create an individual user profile and complete the required The public’s one account for government. | Login.gov identity verification.
The company official should control access to the business’s registration account.
Step 9: Claim the Existing USDOT Record
FMCSA instructs existing registrants to use the same The public’s one account for government. | Login.gov email previously associated with their company official account in the FMCSA Portal.
The authorized official can claim the USDOT record in Motus.
This imports existing company information for review.
Claiming an existing record does not issue a replacement USDOT number.
Step 10: Review and Certify the Company Record
Compare imported information with the company’s current records.
Correct inaccurate fields through the appropriate transaction.
Review the certification before submitting.
The registrant is responsible for the accuracy of the information provided.
Step 11: Grant Outside Access When Appropriate
Motus allows authorized supporting companies to complete applicable filings for registrants.
A company can obtain private administrative assistance without sharing individual The public’s one account for government. | Login.gov passwords.
Review user permissions and remove access that is no longer necessary.
Keep company-account control with the appropriate official.
Step 12: Submit the Correct Update
Use the transaction supported by Motus or the current FMCSA instructions for the specific request.
Depending on the filing type, additional documents or a support ticket may be required.
Do not assume that every name change, ownership change, or reactivation follows the same procedure.
Step 13: Retain Submission Confirmation
Save the confirmation or reference information provided by the system.
Record the submission date and any follow-up requirements.
A submission acknowledgment does not necessarily mean the filing has been accepted.
Step 14: Verify the Accepted Update
Review the company’s registration record after processing.
Confirm the updated information and accepted filing date.
FMCSA directs users to Motus search for registration filings and record activity after May 18, 2026.
If the information does not match the accepted submission, use the official support process.
Step 15: Check the Public Company Snapshot
SAFER provides a public company snapshot with registration and safety information.
Review the legal name, USDOT status, and available company details.
Not all FMCSA systems update at the same time.
A public record may require additional processing time before reflecting a recent change.
What If the Filing Is Rejected?
Review the reason for rejection.
Correct the underlying issue and follow the appropriate resubmission or support procedure.
Keep copies of correspondence and supporting documentation.
Do not create duplicate filings repeatedly without understanding the problem.
What If the USDOT Number Is Inactive?
First determine why it is inactive.
A prior missed biennial update, voluntary inactivation, or another registration action may require different steps.
The current enforcement suspension does not necessarily reverse an inactivation that occurred before the covered relief period.
An inactive USDOT number and revoked operating authority are also separate issues.
Is There a Government Filing Fee?
FMCSA does not charge a government processing fee for a routine MCS-150 biennial update.
Private providers may charge for optional filing assistance.
A service charge should be clearly distinguished from any official government fee.
Does an MCS-150 Update Remove Safety Violations?
No.
The filing maintains company registration information.
It does not automatically erase roadside inspections, crash records, or valid safety violations.
Potentially inaccurate safety data must be addressed through the appropriate review process.
Does an MCS-150 Update Renew UCR?
No.
UCR is a separate annual registration program.
The 2027 UCR season opened October 1, 2026, and covered entities must register and pay before January 1, 2027.
The two obligations should be tracked independently.
