USDOT Number Application: Your Step-by-Step Guide to
Trucking Authority
Whether you’re launching a new fleet or expanding interstate operations, applying for a USDOT Number Application
is your critical first step. As a professional in trucking authority compliance, we’ll walk you through how to apply for DOT number, complete your MC Number Application, and maintain registration compliance
smoothly.
By focusing on the USDOT Number Application, we offer clear, actionable guidance tailored to your needs—whether for interstate commerce, commercial hauling, or hazardous materials transport.
Why the USDOT Number Application Matters
Before diving into the process, let’s address why a USDOT Number Application is essential:
- Compliance: The FMCSA issues a USDOT number to monitor safety performance, inspections, and compliance across fleets. It’s mandatory for most interstate operations.
- Credibility: Brokers and shippers often require a valid number before engaging with a carrier.
- Foundation for Other Permits: Your DOT number is required for the MC Number Application, UCR, IFTA, IRP, and BOC‑3 filings.
MC Number Application – Why and How It Works
What Is the MC Number?
Your MC Number Application grants authority for for-hire interstate operations. While the USDOT Number Application focuses on safety compliance, the MC number authorizes commercial transport of goods across state lines.
Can You Apply at the Same Time?
Yes! You can submit your USDOT Number Application and MC Number Application simultaneously. Doing so streamlines authority issuance and minimizes downtime.
Truck Number Application – State vs. Federal
Some states refer to their own registration process as a “Truck Number Application.” If you operate intrastate, check your state DOT—particularly if you haul hazardous materials or exceed 10,000 lbs GVW. States may still require a USDOT or equivalent registration.
DOT Number Registration – Step by Step
Step 1 – Determine If You Need a USDOT Number
You need a DOT Number Registration if:
- You operate vehicles in interstate commerce.
- Your vehicles weigh over 10,000 lbs. GVW.
- You transport hazardous materials subject to safety regulations.
Step 2 – Gather Required Information
Before applying, compile:
- Business name, address, and contact details.
- Number of vehicles and drivers.
- Vehicle weight, cargo types, and classification.
- Operation type: for-hire, private, interstate or intrastate.
Step 3 – Complete the MCS‑150 Form
Fill out the MCS‑150 Form online via the FMCSA portal. Accuracy is key—errors or misclassifications can delay approval.
Step 4 – File Biennial Update
Every two years you must update your company’s MCS‑150 information—failure to do so can lead to deactivation.
Step 5 – Compliance Registrations After Application
Once your DOT Number Registration is approved:
- File UCR (Unified Carrier Registration).
- Apply for apportioned plates under IRP.
- Register for IFTA fuel tax reporting.
- Submit BOC‑3 to designate process agents.
Common Mistakes with DOT & MC Number Application
Watch for these pitfalls when applying:
- Incomplete or inaccurate information on your USDOT or MC applications.
- Misclassified operation types.
- Skipping the biennial update, risking deactivation.
- Overlooking state regulations for intrastate operations.
