The post office sits in southwestern Arkansas near the Louisiana border, where dispersed rural settlement patterns make traditional street delivery impractical. The 183 PO Boxes serve both local residents and 22 businesses that maintain a presence in this unincorporated community. This isn't a failed delivery system but rather one adapted to the realities of low-density rural geography.
The single highway route reflects rural corridor geography rather than a street grid.
ZIP Code 71840 is designated for PO Box delivery only; business establishment and employment data are not available.
