Topawa sits at the heart of the Tohono O'odham Nation, where 240 residents spread across 68.6 square miles of southern Arizona desert. Nearly 100% of the population is Native American. The post office on Main Street serves as the only mail delivery point for 85 households, maintaining 71 PO Boxes for a community where street delivery doesn't exist.
The PO Box adoption rate of 0.84 tells you something important: this isn't about convenience. It's about necessity. When you're this remote, when roads don't have the kind of names and numbers that mail carriers need, when homes sit far apart across vast distances, the post office becomes the place where the community connects with the outside world. Every resident depends on their box.
At 38 years old, the median age sits close to the national average. But the household size tells a different story. With 2.8 people per household, you're seeing extended families living together. That pattern is typical of tribal communities where multiple generations share homes and child-rearing duties are communal.
The median household income of $35,625 ranks well below national figures, but the median home value data isn't available for this area. The community maintains its own economic patterns, its own rhythms. Only one business operates here with a formal ZIP+4 record. This is residential land, community land, where 48 residents participate in the civilian labor force.
Topawa's position puts it roughly 60 miles southwest of Tucson, deep in territory where the desert stretches uninterrupted. The nearest city services require a substantial drive. The post office isn't just handling mail. It's providing the infrastructure that keeps residents connected to government services, tribal administration, healthcare appointments, and family scattered across other reservations or cities.
With only Main Street appearing in delivery records, the street infrastructure here is minimal. The single named building reference is simply 'Postmaster,' confirming that the post office is the central point for all mail service. This isn't a place built around street grids. It's tribal land where traditional settlement patterns don't translate to conventional addressing systems.
ZIP Code 85639 has 240 residents and 85 households (average 2.82 persons per household). The median age is 38.0 years, about the same as the state (38.9) and about the same as the nation (38.8). The gender split is 46.3% male and 53.8% female, which is lower than the state male share (49.5%), making this a female-majority area. Largest groups are American Indian & Alaska Native (99.6%, much higher than the state average of 4.5% and well above the national average of 1.1%) and Hispanic or Latino (3.3%); Hispanic or Latino residents make up 3.3%, which is much lower than the state average (30.7%), and American Indian & Alaska Native share is much higher than both the state (4.5%) and national averages (1.1%).
