If your USDOT Number is active, online updates can be made via your FMCSA Portal account. Don't have an FMCSA Portal Account to Make Online Changes? 

If your number is inactive, you will need to submit a paper form. See our Registration Forms page for more information.

Check SAFER to verify your current USDOT Number status.

Biennial Update

Federal Motor Carrier Safety Administration (FMCSA) requires all entities under its jurisdiction to update their information every two years. You are required to provide this update every two years even if your company has not changed its information, has ceased interstate operations since the last update, or is no longer in business and you did not notify FMCSA.

Failure to complete a Biennial Update will result in deactivation of your USDOT number and may result in civil penalties of up to $1,000 per day, not to exceed $10,000.

Updating your information is free. We have included instructions below to help you complete your biennial update.

• Deadlines for Filing an Update
• Update via the FMCSA Ask Website
• Update via US Mail (may delay the process)

What is the Deadline to Update?

Filing schedule: Each motor carrier or intermodal equipment provider must file the appropriate form at the following times:

• Before it begins operations; and
• Every 24 months according to the following schedule:

If the next-to-last digit of its USDOT Number is odd, the motor carrier or intermodal equipment provider shall file its update in every odd-numbered calendar year. If the next-to-last digit of the USDOT Number is even, the motor carrier or intermodal equipment provider shall file its update in every even-numbered calendar year.
