Area code 936 serves southeastern Texas, including cities such as Conroe, Lufkin, Nacogdoches, and Huntsville. Established in 2000 from a split of area code 409, it covers a diverse region that blends forested landscapes with growing suburban areas north of Houston. The area is home to Sam Houston State University, major prison facilities, and several state parks. With a balance of education, agriculture, and light industry, 936 continues to serve as a crucial communication link for East Texas. It is widely used in both rural communities and rapidly developing exurbs.
