The ZIP's delivery infrastructure reflects its role as a rural service hub. Two rural carrier routes and one city carrier route extend from this post office, serving both State Road 62 and E Main St. This mixed delivery pattern isn't unusual for small Indiana river communities, where settlement patterns follow historic transportation corridors rather than grid layouts. The post office itself is classified as a community post office (facility code P) without city carrier delivery within the core ZIP boundaries.
Friendship's tiny residential population of 12 people produces a household ratio of 1.71 persons per occupied unit, which is below Indiana's statewide average. The median age of 47.7 years skews older than typical working-age communities. Of the 8 total housing units recorded in the 2020 Census, 7 are occupied year-round and 1 sits vacant. There are no seasonal vacation properties here. The 5 business establishments employ 71 people, suggesting most employment happens outside the immediate ZIP boundaries with workers commuting in.
The high PO Box adoption rate tells the real story. When a post office maintains six times more boxes than local households, it's functioning as a regional mail hub for customers scattered across rural areas. These surrounding residents don't have street delivery at their homes, so they travel to Friendship's post office to collect mail. This pattern is common along the Ohio River valley, where small river towns historically served as commercial centers for agricultural hinterlands. The 15 business customers and 42 total PO Boxes represent a service footprint extending well beyond the 0.005 square miles of land area officially assigned to ZIP 47021.
The street network is minimal, with State Road 62 serving as the primary regional corridor and E Main St representing the historic town center. This limited street infrastructure is typical of small river communities that developed as single-street settlements along transportation routes.
ZIP Code 47021 has 12 residents and 7 households (average 1.71 persons per household).

The gender split is 66.7% male and 33.3% female, which is much higher than the national male share (49.1%), making this a male-majority area.
