Do I need to file an MCS-150?
In most cases, if you have a USDOT number you must keep your MCS-150 information current. Many carriers must file a biennial update every two years even if nothing changed.
DIY service: we generate the PDF for you to review. You submit it yourself.
You likely need to file if…
- You have an active USDOT number (owner-operator or fleet)
- Your biennial update is due (based on USDOT number schedule)
- Your company information changed since the last update
- You’re returning to operation and your record is outdated
Changes that usually trigger an update
If any of these changed, you should update your registration information instead of waiting:
- Address, phone number, or email
- Company officers / ownership details
- Number of drivers or power units
- Operations (interstate/intrastate), cargo type, HM status, etc.
If you don’t file
Missing updates can lead to deactivation of your USDOT number and other compliance issues. If you’re unsure, it’s safer to confirm your record and update if needed.
