Lukachukai sits in the Chuska Mountains of northeastern Arizona, serving Navajo communities across 203 square miles of Apache County. This isn't a town in the conventional sense. It's a chapter of the Navajo Nation where 1,889 of the 1,912 residents (99%) are Native American. The post office connects families and hogans scattered across a vast mountain territory where traditional land use patterns don't align with standard street addressing.
The Lukachukai post office operates as a Community Post Office (facility code C) and maintains 542 PO Boxes for the 601 households in this area. That 90% adoption rate shows near-universal reliance on PO Boxes. While this isn't technically designated a PO Box Only Zone, the reality is that most mail reaches families through boxes. A single Highway Contract route (H route) serves some locations along Highway 191, but the sparse addressing infrastructure (just one street name appears in postal records) means PO Boxes handle the bulk of mail delivery across 203 square miles of mountain terrain.
Families here average 3.2 people per household, a pattern that shows the multi-generational living arrangements common in Navajo communities. Median age is 34.8 years. With a median household income of $33,015, this is a working community where 296 people work in public administration (likely for the Navajo Nation government), 276 in education and healthcare, and 185 in transportation. Work from home accounts for 41% of the workforce, though this figure likely includes traditional economic activities on the reservation.
The aliases tell the story of the communities served: Upper Wheatfields, Upper Greasewood Trading Post, and Greasewood Springs. These names appear in postal records but aren't valid for mailing. Mail sent to Chinle (also an accepted alias) or Lukachukai will reach the same post office. The ZIP code dates back to before October 2004, when USPS tracking began, showing this has been an established mail access point for decades.
For families across this mountain chapter, the Lukachukai post office isn't a convenience. It's the primary connection to mail, packages, prescriptions, and government documents. People drive from across the territory to this central point because there's no practical alternative for most locations. The post office handles General Delivery (G route) for those without boxes, but the 542 boxes at a facility serving 601 households shows that nearly every family maintains one.
Only one street appears in postal records. Highway Contract delivery serves scattered locations, but PO Boxes handle most mail.
ZIP Code 86507 has 1,912 residents and 601 households (average 3.18 persons per household). The median age is 34.8 years, younger than the state (38.9) and younger than the nation (38.8). The gender split is 47.3% male and 52.7% female, which is slightly lower than the state male share (49.5%), making this a female-majority area. Largest groups are American Indian & Alaska Native (98.8%, much higher than the state average of 4.5% and well above the national average of 1.1%) and Hispanic or Latino (0.9%); Hispanic or Latino residents make up 0.9%, 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%).
