Already have a USDOT number? Carrier Compliance HQ helps you update your FMCSA profile, keep your records current, and stay ahead of future compliance deadlines.
This page is for carriers who already have a USDOT number and need to keep their FMCSA record current — it is separate from applying for a brand-new DOT number. If you still need to get a USDOT number, start there instead.
The Biennial Update Cycle
Typical cycle; timing is based on your USDOT number.
The MCS-150 is the Motor Carrier Identification Report maintained by the FMCSA. Carriers use this filing to update information associated with their USDOT number, including company details, operation classifications, fleet information, and other business information.
Many carriers must submit a biennial update every two years, even if no information has changed.
Businesses operating commercial vehicles across state lines.
Certain intrastate operations may also be required to maintain updated information.
Independent operators maintaining active USDOT numbers.
Businesses updating fleet, operational, or contact information.
Requirements vary depending on operation type and USDOT status. Carrier Compliance HQ reviews the information provided to help identify the appropriate filing path.
