Registering for a DOT number (Department of Transportation number) is necessary for certain commercial vehicles and businesses engaged in interstate commerce in the United States. Here’s a step-by-step guide on how to register for a DOT number:

1. Determine if You Need a DOT Number: DOT numbers are required for commercial vehicles that meet specific criteria. Generally, you need a DOT number if:

   • Your vehicle has a gross vehicle weight rating (GVWR) or gross combination weight rating (GCWR) of 10,001 pounds or more.
   • Your vehicle is used to transport more than 8 passengers (including the driver) for compensation.
   • Your vehicle is used to transport more than 15 passengers (including the driver) not for compensation.
   • Your vehicle is used to transport hazardous materials in quantities that require placarding.

   • Employer Identification Number (EIN) or Social Security Number (SSN) of the business owner.
   • Vehicle information including make, model, year, VIN (Vehicle Identification Number), GVWR, and ownership details.
