The Federal Motor Carrier Safety Administration (FMCSA) requires all regulated companies (every motor carrier or intermodal equipment provider) to update their registration details at least once every two years. This process is commonly known as the Biennial Update, MCS-150 Update, or USDOT Update. But biennial updates aren’t a one-time requirement. Any major changes in your business also require you to submit an updated form MCS-150
Motor carriers must update their MCS-150 every two years, but the exact deadline isn’t the same for everyone. That’s because your filing date depends on your USDOT number.
Here’s how it works:
The second-to-last digit of your USDOT number tells you the year you need to file your MCS-150 update:
Example:
USDOT Number XXXXX15 → File in an odd year (like 2025, 2027, etc.)
USDOT Number XXXXX25 → File in an even year (like 2024, 2026, etc.)
To figure out the month your MCS-150 update is due, simply check the last digit of your USDOT number. Each digit from 1 to 0 represents a specific month, and your update must be filed by the last day of that month.
Example:
If your USDOT number ends in XXXXX35:
So, your update is due by the last day of May 2025.
If your USDOT number ends in: | Must file by the last day of: |
---|---|
1 | January |
2 | February |
3 | March |
4 | April |
5 | May |
6 | June |
7 | July |
8 | August |
9 | September |
0 | October |
In addition to the biennial update, the FMCSA requires you to update your registration within 30 days of any major changes — like your company’s address, phone number, or number of vehicles.
If you’ve already filed an update within 12 months before your scheduled biennial update, the FMCSA considers that sufficient and won’t send you a biennial update reminder until your next scheduled filing.
Failing to file your MCS-150 update on time is more than a minor mistake—it can have serious consequences for your business. The FMCSA requires every motor carrier to update their information every two years, even if nothing has changed, your company stopped operating interstate, or you’re no longer in business but haven’t officially informed them.
If you miss the deadline, here’s what can happen:
To avoid fines and interruptions, ensure your information is accurate and your updates are filed on time.

You must update your MCS-150 form at least once every two years, even if your company’s information hasn’t changed. This update is known as a biennial update and is required by the Federal Motor Carrier Safety Administration (FMCSA). The due date for your update is based on the last two digits of your USDOT number:
Filing your MCS-150 form on time is essential to maintaining compliance with FMCSA regulations. Many carriers fall out of compliance simply by missing the required biennial update. Timely updates are critical not only for regulatory compliance but also for ensuring accurate safety records, financial stability, and the integrity of the transportation industry.
Failing to file the MCS-150 by the deadline can lead to serious consequences, including deactivation of your USDOT number and civil penalties of up to $1,000 per day. Without an active DOT number, carriers lose their operating authority and are legally prohibited from conducting business.
Filing or updating your MCS-150 means giving the FMCSA a clear picture of your business—how you operate, what you haul, and how safe you are. This info keeps your records current and your USDOT number active.
Here’s what you’ll need to complete your MCS-150:
One of the most overlooked parts of the MCS-150 update is your Vehicle Miles Traveled (VMT), but skipping it can lead to further challenges. If you leave the VMT section blank or outdated, the FMCSA will flag your record as “VMT outdated.” That might sound harmless, but it can result in:
