Zip code 78640 covers Kyle, one of the fastest-growing cities in the United States, located in Hays County approximately 20 miles south of downtown Austin along Interstate 35.

The city spans both sides of I-35 and extends west toward the Blanco River and east toward SH-21 and Plum Creek. The landscape is transitional, with flat Blackland Prairie in the eastern portions and gradually rolling terrain to the west approaching the Edwards Plateau. Kyle incorporated in 1928 and historically served as a railroad and farming community before the Austin metro expansion transformed it into a bedroom community.
