Motor carriers who do business within the state of Texas are required to apply for a registration number from the Texas Department of Motor Vehicles (DMV). Although the registration is filed with the Texas Department of Transportation, the Texas DMV is administering the filings as of November 2009. Other vehicles may be added to an existing registration by filing the Additional Motor Carrier Equipment Report, Form 1900. Texas DMV provides motor carriers the option to file online using the Motor Carrier Credentialing System (MCCS).

Access the Additional Motor Carrier Equipment Report, Form 1900, on the Texas DMV website. Print the form by clicking on the printer icon in the upper-left of the form screen.

Fill in your Texas motor carrier registration number in the upper-right of the form.

Complete the name, phone number, street address and mailing address of your business as it appears on your motor carrier registration.

Fill in the make, unit number, model year, VIN and type of motor carrier operation where indicated for each additional vehicle you wish to register.

Indicate the method of payment and enter the credit card account number and expiration date, if applicable. Calculate the fees due by multiplying the registration fee by the number of vehicles being added for either a one- or two-year registration period.

Sign the form and print your name and title, business owner, for example.

Mail the completed form to the Texas Department of Motor Vehicles, Motor Carrier Division, P. O. Box 12984, Austin, Texas, 78711-2984, or fax the form including payment information to 512-465-3521. You may include a check or money order payable to the Texas Department of Motor Vehicles with a mailed application.


If you want to use the MCCS online system for registration, call 888-368-4689 to obtain a login ID and PIN number.


It is the motor carrier's responsibility to assure that its insurance company files proof of insurance for all registered vehicles with the Texas DMV.
