Every trucking company operating under a USDOT number must keep its registration current. One of the most important parts of that process is filing the MCS-150 form. This form ensures the Federal Motor Carrier Safety Administration (FMCSA) has accurate information about your operation.
What Is the MCS-150?
The MCS-150, or Motor Carrier Identification Report, provides essential company details to the FMCSA. It includes your business name, address, USDOT number, number of vehicles and drivers, and the types of cargo you transport.
This data allows FMCSA to evaluate safety, track performance, and maintain accurate records.
Filing the MCS-150 is required for all carriers, even if no information changes. It’s not a one-time form — it’s a recurring part of staying compliant.
Why the MCS-150 Matters
Accurate filing affects more than compliance. It can also impact your insurance rates and safety score. Carriers who file late or skip updates may see their USDOT number deactivated, which means they can’t legally operate until it’s reinstated.
Additionally, incorrect data can create confusion during roadside inspections or when applying for insurance coverage.
For example, if your company reports fewer vehicles than it operates, that discrepancy could raise red flags with regulators and insurers alike.
How Often Should You File?
You must update your MCS-150 every two years, based on the last digit of your USDOT number. FMCSA will deactivate your number if you miss your update window. You can check your next filing date on the FMCSA Registration Website.
Many carriers also choose to file early when they add trucks, change addresses, or modify cargo types. Keeping your file current avoids issues during audits or renewals.
How to File Your MCS-150
There are two main ways to file:
Online through FMCSA’s website – the fastest, easiest option.
By mail – downloading, completing, and submitting a paper form.
Before submitting, review all details for accuracy. Even small errors—like a mistyped VIN or address—can delay approval.

How It Impacts Insurance
Insurance carriers use FMCSA data when determining risk. A properly filed and accurate MCS-150 can lead to better pricing and smoother renewals.
As a result, keeping this form up to date helps your business stay both compliant and financially protected.
If your MCS-150 isn’t current, your safety score may not reflect your actual performance, which can increase premiums unnecessarily.
