The MCS-150 form, commonly referred to as the Biennial update, is a federal mandate per regulation Title 49 Code of Federal Regulations, Section §390.19T (also known as CFR Title 49 Section 390.201T). It is a requirement for all owners of a U.S. DOT Number, regardless of fleet size and scale of operations.
A U.S. DOT Number never expires, but the Department of Transportation requires filing an update in three specific cases:
The last digit of the DOT Number corresponds to the month of the deadline The digits before the last of the DOT Number corresponds to the year of the deadline
Keeping your MCS-150 is critical as falling out of date could lead to your
USDOT# deactivated along with thousands of dollars in penalties.
This is one of the most frequently asked questions. The answer is yes, one must file a Biennial Update on a specific month and year combination regardless of when the DOT numbered was opened.
Biennial Update filings must be completed every 24 months. If you miss your initial filing deadline, your next scheduled update will have been more than 24 months from the date you had established your DOT number. As such, if you have recently opened your business you may have to file the initial Biennial Update sooner than two years. For more information please reference regulation FMCSR 390.201T.
You’re current USDOT # includes the information you need to determine when your MCS-150 renewal is due.
If the second to last number is ODD, your MCS form is due during odd years. (IE: 2019, 2021, 2023)
With the second to last number being an even number, your MCS form is due during even y ears. (IE: 2020, 2022, etc)
This number represents the month that your biennial DOT number update needs to be filed.
