When should USDOT information be updated?
The biennial schedule is a minimum recurring review—not permission to leave a material error in the record for two years. FMCSA instructs registrants to report changes to information such as address, telephone, email, and power units rather than waiting for the next scheduled month.
Before filing, decide whether the situation is a routine registration change or a more consequential event such as a legal-name change, ownership or entity change, operating-authority change, reactivation, or out-of-business notice. Those actions may require supporting documentation or separate registration steps.
Legal name, DBA, address, and contact changes
Use the legal name belonging to the entity that owns the USDOT number. USDOT numbers are not transferable to a different legal person. A new owner or a newly formed legal entity should not simply replace the name on another entity’s record to inherit its registration history.
The principal place of business should identify the real location where the company conducts the relevant transportation business and maintains qualifying records. The mailing address can differ. Keep the public telephone, email, and company official current so FMCSA notices and account-recovery messages reach the right people.
| Change | Review before submitting |
|---|---|
| Legal business name | Entity documents, exact spelling, authority-name record, insurance and state records |
| DBA or trade name | Whether the trade name is current and belongs to the same legal entity |
| Physical address | Whether it qualifies as the principal place of business and matches supporting records |
| Mailing address | Where official correspondence should be delivered |
| Telephone and email | Whether the company controls them and actively monitors them |
| Company official | Whether the person has authority and can complete secure Motus access |
Operation and cargo changes
Classifications should describe what the company actually does now. A carrier may change between private and for-hire activity, add interstate operations, transport different cargo, begin passenger service, or enter hazardous-materials operations. Some changes affect more than the MCS-150 record and may trigger authority, insurance, safety-permit, or state requirements.
- Interstate, intrastate hazardous-materials, or intrastate non-hazardous operation status.
- Authorized-for-hire, exempt-for-hire, or private classifications where applicable.
- Carrier, broker, freight-forwarder, cargo-tank, or intermodal roles.
- Cargo classifications and hazardous-materials activity.
- Passenger operation type and service categories.
Vehicle, power-unit, and driver changes
Update the operation as it exists—not the fleet the company hopes to buy or the driver roster from a different date. Separate owned, term-leased, and trip-leased equipment using the definitions requested in the filing. Count drivers and CDL drivers consistently, including owner-operators when they are drivers for the registered operation.
Large unexplained changes can affect how outside parties interpret the record. Keep a short internal note showing the date and source used for the counts so the company can answer future questions and complete the next update consistently.
How to update MCS-150 mileage correctly
Mileage is one of the most frequently misunderstood fields. Report the total mileage requested for the fleet and pair it with the correct mileage year. Do not enter only one truck’s mileage when the field calls for fleet mileage, and do not use the current year automatically when the instructions request the prior completed calendar year.
- Identify the calendar year requested by the filing.
- Gather mileage for every vehicle included in the registered operation for that period.
- Remove duplicate mileage when the same vehicle appears in multiple internal systems.
- Document any reasonable method used when exact records require reconstruction.
- Enter the total and the corresponding year together, then review both before certification.
What an MCS-150 change does not automatically update
The USDOT record and operating-authority record are related but not interchangeable. A company name or address change may require separate authority documentation. Insurance filings are generally submitted by the insurance company. BOC-3, UCR, IRP, IFTA, state corporate records, tax accounts, and permits may each need their own update.
- MC/FF/MX operating-authority record.
- Insurance or surety filings.
- BOC-3 process-agent designation.
- Unified Carrier Registration.
- IRP, IFTA, vehicle registration, or state permits.
- Secretary of State and IRS entity records.
When supporting documents may be required
Routine data changes may be straightforward, but identity, legal-name, EIN, ownership, and authority-related changes often require documentation. FMCSA’s registration-forms table identifies examples such as government ID, entity documents, IRS documentation, and operating-authority change forms.
Submit documents for the exact requested purpose and protect sensitive information. A mismatch between the legal name in Motus, the signer’s role, and the supporting document can delay the transaction even when the requested change is legitimate.
A practical before-and-after checklist
| Before submission | After processing |
|---|---|
| Compare the current public record with company documents | Verify the MCS-150 date and USDOT status |
| Identify every registration affected by the change | Confirm the legal name, address, contacts, and classifications |
| Prepare current fleet, driver, and mileage data | Check fleet, driver, and mileage fields for transcription errors |
| Gather required ID and supporting documents | Save the transaction confirmation and supporting-file copy |
| Have the correct official certify the information | Update separate authority, insurance, UCR, or state records as needed |

Do I wait for the biennial month to change my address?
No. Important registration changes should be reported when they occur rather than left inaccurate until the scheduled filing month.
Can I change the legal name on the MCS-150?
A legitimate name change may be requested, but supporting entity documents and a separate operating-authority name change may also be required.
Can a new owner take over the old USDOT number?
USDOT numbers belong to the same legal person and are not transferable. Ownership and entity changes require careful review.
What mileage should I enter?
Use the total mileage and reporting year requested by the current filing instructions; do not automatically use one vehicle or the current partial year.
Does adding trucks require an immediate update?
Keep the USDOT operating profile accurate. Review whether the power-unit change should be reported now and whether insurance or other registrations also need attention.
Does the MCS-150 update my MC authority address?
Not necessarily. FMCSA treats USDOT and authority record changes as related but separate actions in some situations.
Does changing cargo create other requirements?
It can. Hazardous materials, passengers, household goods, and new for-hire operations may trigger additional authority, insurance, permit, or safety obligations.
Will an early change count as the biennial update?
It may when completed within the applicable period, but confirm the current Motus action and FMCSA schedule for the company.
