Are You Going Out of Business or No Longer Using Your USDOT number?

Shutting Down Operations
You should file “Out of Business” within 30 days of going out of business or if you are still in business but no longer using your USDOT number. The only way to deactivate your number is by filing an MCS-150 form. You cannot just call the FMCSA and tell them you are no longer using it.

Update Every Two Years

A carrier must provide this update every two years - even if the 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 the FMCSA

When Are Biennial Updates Due?

If the next-to-last digit of your USDOT number is odd, you file in odd-numbered years. If it is even, you file in even-numbered years. The last digit tells you the month it is due; 1: January, 2: February, 0: October.


Any changes/updates that occur outside your required biennial update month and year, such as adding or removing drivers or vehicles, are considered an “Update.” You should file an Update within 30 days of the change happening.

VMT Outdated

This can easily be overlooked when filing your biennial update.
If you fail to update your “Vehicle Miles Traveled,” you will be flagged as “VMT outdated” in the FMCSA’s database. Accurately reflecting your mileage is extremely important because it is used to calculate Crash Indicator Behavior Analysis and Unsafe Driving and Safety Improvement Categories or “BASICs” percentiles. Incorrect information can negatively affect your Safety Measurement System (SMS) scores, which could negatively impact your insurance premiums.


If you previously filed “Out of Business” or were deactivated by the FMCSA and want to start using your number again you will need to file an MCS-150 form to “Reactivate” your USDOT number.

Edit Update

Any time information changes regarding your business operation, such as the business address, phone number, business name, or other details, you should promptly update your USDOT with FMCSA by filing an Edit.

Filing Your Biennial Update
Can Be Simple!

Am I Exempt From Filing A Biennial Update?

For private, exempt for-hire, and for-hire motor carriers of passengers or cargo, there are currently NO exemptions from filing a biennial update (this includes Ag-exempt farmers). If you have a USDOT number, you must keep it up-to-date OR file an “Out of Business” if you are no longer using it. Even if you find out you don’t NEED a USDOT number, if it’s active in the FMCSA database, you must update or deactivate it.
Brokers and freight forwarders are NOT required to file the biennial update every two years. If you have any changes, such as a name or address change, you must file a 5889 form.

Need to know

Biennial updates are not due based on the “anniversary” date of when you received your USDOT number but are due every two years as determined by the last two digits of your number. That means it is possible to get your USDOT number and have to file your BU a few months later.

Even if nothing has changed with your business since your last filing, you must still file your BU when it is due.

The FMCSA requires that they be notified within 30 days of ANY change of operation between filing dates (e.g., address, phone number, driver or vehicle changes, or operation changes).

Failure to notify the FMCSA of any changes may subject you to fines and deactivation of your USDOT number.
