The ZIP serves a sparse population spread across the area between Robards and the Vanderburgh County line. Five local businesses maintain addresses here, and one named building appears in postal records. The post office's carrier delivery indicator shows limited home delivery service, which is common for crossroads communities where scattered settlement patterns make centralized box service more practical.
The single street route follows State Route 136 West, suggesting this is a highway-oriented service point rather than a traditional town grid. The limited street infrastructure reflects a rural crossroads pattern where the post office serves as a gathering point for scattered residences along the county road network.
