MCS-150 update service
File your MCS-150 update before FMCSA parks your USDOT number.
MotorCarrier.ai helps carriers update FMCSA company records, handle biennial DOT updates, and fix stale USDOT information before it turns into deactivation, roadside drama, or broker onboarding friction.
Quick answer
The MCS-150 keeps your FMCSA record current. Carriers must update it at least every two years, and sooner when key company or operation details change. Miss it, and your USDOT number can be deactivated — which is the compliance equivalent of blowing a steer tire at speed.
What we handle
- Biennial due-date check
- USDOT company information review
- Operation, mileage, vehicle, and driver updates
- Address, contact, and officer changes
- Authority-change routing when MCS-150 is not enough
- Confirmation and recordkeeping handoff
Who needs this page?
Active carriers
Your USDOT record needs to match reality: trucks, drivers, mileage, contact info, cargo, and operation type.
Carriers with stale records
If the business moved, changed contacts, added units, or shifted operations, update before someone else notices first.
New owners cleaning up records
Buying or restructuring a carrier often reveals old FMCSA data that needs disciplined cleanup.
What happens if you skip the MCS-150?
USDOT deactivation
FMCSA can deactivate carriers that miss biennial updates. That is not a branding problem; that is an operating problem.
Roadside and audit friction
Bad records create questions during inspections, audits, and broker checks.
Insurance and broker mismatch
When FMCSA data does not match your current operation, everyone downstream starts asking annoying but valid questions.
Separate forms may be needed
Some changes cannot be solved by MCS-150 alone. Authority type changes, name changes, and transfers may need additional FMCSA workflows.
MCS-150 update FAQ
Who needs an MCS-150 update?
Motor carriers, brokers, freight forwarders, and other FMCSA-registered businesses must keep their company record current and file biennial MCS-150 updates based on their USDOT number schedule.
When is my biennial update due?
Your due month is based on the last digit of your USDOT number, and odd/even year timing is based on the next-to-last digit. If that sounds like a compliance fortune cookie, we can help decode it.
What changes require an MCS-150 update?
Common updates include address, phone, email, company officers, mileage, power units, drivers, cargo, operation type, and business classification changes.
What happens if I miss the MCS-150 update?
FMCSA can deactivate your USDOT number, which can stop operations, create roadside trouble, and make brokers very uninterested in hearing excuses.
Is MCS-150 the same as application changes?
MCS-150 updates your FMCSA company/safety record. Some authority changes may require separate FMCSA forms or portal work in addition to the MCS-150.
