The term you will encounter
GDN stands for General Distinguishing Number, a term used in Texas dealer licensing. TxDMV issues dealer licenses for defined activities. Understanding the name is helpful, but it does not tell you which licensing direction suits your intended business.
What a GDN allows
A GDN is the basic Texas dealer license that allows you to buy, sell or exchange the type of used vehicle for which it is issued. TxDMV divides GDN licenses into categories — independent motor vehicle, motorcycle, travel trailer, trailer/semi-trailer, wholesale and others — each with its own privileges, such as dealer temporary tags and metal dealer license plates for that vehicle type. Some categories require a surety bond and some are exempt. Wanting more than one type means more than one application.
Your business is the important context
The vehicles you intend to handle and the way you plan to operate can shape the licensing conversation. Treating every dealer license as interchangeable can create confusion before you have even started. One of the first things we determine with a client is not simply whether they need a dealer license, but which license structure actually fits the way they intend to operate.
