The trucking industry in Texas is one of the largest in the United States, serving as a major hub for interstate and intrastate commerce. Whether you’re moving oil and gas, agricultural products, manufactured goods, or general freight, operating legally is critical. One of the first requirements for trucking companies and owner-operators is obtaining a USDOT Number.

If you’re new to trucking or planning to start a transportation business in Texas, understanding what a USDOT Number is, who needs it, and how to apply is essential. Without it, you risk fines, shutdowns, and lost opportunities.

What Is a USDOT Number?

A USDOT Number is a unique identifier issued by the Federal Motor Carrier Safety Administration (FMCSA). It is used to track a company’s safety record, compliance, and inspections.

Think of it as a “tracking ID” for trucking businesses. Every time your trucks are inspected, involved in an accident, or audited, the results are recorded under your USDOT Number. This helps the FMCSA monitor safety standards and ensure carriers are following regulations.

Unlike an MC Number, which grants operating authority for interstate for-hire carriers, a USDOT Number is more about safety compliance.

Who Needs a USDOT Number in Texas?

Not every vehicle or business requires a USDOT Number. In Texas, you must obtain a USDOT Number if you operate:

1. A commercial vehicle that transports passengers or property in interstate commerce and meets any of the following conditions:

• The vehicle has a gross vehicle weight rating (GVWR) or gross combination weight rating (GCWR) of 10,001 lbs. or more.
• The vehicle is used to transport hazardous materials requiring placards.
• The vehicle is designed or used to transport more than 8 passengers (including the driver) for compensation.
• The vehicle is designed or used to transport more than 15 passengers (including the driver), not for compensation.

• Has a GVWR or GCWR of 26,001 lbs. or more,
• Transports hazardous materials requiring placards, or
• Carries 15 or more passengers.

So, whether you’re an independent owner-operator or managing a fleet, chances are high that you’ll need a USDOT Number if you plan to operate in Texas.

Why a USDOT Number Is Important for Texas Truckers

Having a USDOT Number is not just about compliance—it also helps your business in several ways:

• Legal Requirement: Without it, you cannot legally operate commercial vehicles subject to FMCSA rules.
• Avoid Fines: Texas law enforcement actively checks for USDOT Numbers. Operating without one can result in costly penalties.
• Safety Monitoring: Helps build your company’s safety reputation, which is critical for getting contracts.
• Insurance Approval: Many insurance companies require a valid USDOT Number before issuing coverage.
• Broker and Shipper Trust: Many brokers and shippers won’t hire carriers without an active USDOT Number.

How to Apply for a USDOT Number in Texas

Applying for a USDOT Number can be done online through the FMCSA’s Unified Registration System (URS). Here’s a step-by-step guide:

1. Gather Required Information

You’ll need details about your business, such as:

• Legal business name and address
• Employer Identification Number (EIN) or Social Security Number (SSN)
• Company structure (sole proprietor, partnership, corporation, LLC)
• Type of operation (for-hire, private, exempt, passenger, etc.)
• Vehicle details (weight, type, number of vehicles)
• Types of cargo transported

2. File the Application Online

Visit the FMCSA URS portal and complete the USDOT Number application.

3. Pay the Applicable Fees

The USDOT Number itself does not require a fee. However, if you are also applying for operating authority (MC Number), a $300 fee per authority will apply.

4. Receive Your USDOT Number

Once your application is submitted, the FMCSA will issue your USDOT Number. You’ll need to display it on both sides of your commercial vehicles.

Texas-Specific Requirements

In addition to the federal USDOT Number, Texas has its own requirements for carriers:

1. Texas Intrastate Operating Authority – Carriers operating only within Texas may need to register with the Texas Department of Motor Vehicles (TxDMV).
2. Unified Carrier Registration (UCR) – All carriers with a USDOT Number must register annually and pay fees based on fleet size.
3. International Registration Plan (IRP) and International Fuel Tax Agreement (IFTA) – If you operate across state lines, these programs are mandatory.

Common Mistakes Truckers Make with USDOT Numbers

1. Not Updating Information – Carriers must update their USDOT information every two years (biennial update), even if nothing changes.
2. Applying Under the Wrong Business Type – Mistakes in classification can delay the application.
3. Operating Without Insurance – Insurance filings are often overlooked but are critical for compliance.
4. Confusing USDOT with MC Number – Many new truckers assume they only need one or the other, but in many cases, you need both.
