Genoa, AR

Genoa is a census-designated place and unincorporated community in Miller County, about three kilometers east of Texarkana along Arkansas Highway 196. The highway is the clearest way to place it: Genoa belongs to the Texarkana area’s network of roads and services while retaining its own postal name. It first appeared as a CDP in the 2020 census, when 972 residents were counted.

The community’s present-day geography is organized around that corridor. The Genoa Post Office operates on State Highway 196 under the 71840 ZIP code, while most of the surrounding community uses ZIP code 71854. That split offers a useful clue to the place: one named community spread along a highway at the edge of a larger regional center, with postal service preserving Genoa as a distinct locality. The route keeps Genoa oriented toward Texarkana for regional institutions and services. For someone considering the area, Genoa is best understood through its highway connection, postal presence, and close relationship with Texarkana.
