ZIP Code 86035 in Leuppx, AZ

Community Overview

Leupp is a Navajo Nation community in Coconino County, Arizona, serving 1,694 residents across 608 square miles of reservation land. Of these residents, 1,642 (97%) are Native American, making this one of the most homogeneous Navajo communities with PO Box classification in the postal system.

How Mail Delivery Works

Despite its PO Box classification, mail delivery here works differently than most Classified as a PO Box ZIPs. The community has rural carrier delivery covering 68 different routes, mostly Navajo numbered roads like Navajo 2, Navajo 6730, and Navajo 6821. There are no PO boxes maintained at the facility. Instead, residents receive mail via one rural route serving the scattered homes across this vast territory.

The Road Network

The road network tells the story of this community's geography. Street names include Navajo routes (37 different numbered routes), Bird Springs routes (serving the northern area), and Tolani Lake routes (serving the western region). These aren't traditional streets but rather numbered routes crossing desert terrain, connecting homes separated by miles of open land.

Population and Household Characteristics

Household structure differs from mainstream American patterns. With 1,694 people living in 509 households, the ratio is 3.3 people per household, higher than the national average of 2.5. This reflects extended family living arrangements common in Navajo culture, where multiple generations often share homes.

Economic Context

Employment patterns show strong ties to tribal governance and transportation sectors. Of the employed population, 191 people work in public administration (mostly tribal government), and 399 work in transportation, warehousing, and utilities. The area sits along Arizona Highway 99, a key corridor for the region. Remarkably, 53.4% of workers work from home, though this likely includes ranching, traditional crafts, and home-based economic activities rather than remote office work.

Educational attainment is low compared to urban areas. Only 10% of adults age 25 and over hold a bachelor's degree or higher. Median household income is $51,765, and median home values are $59,700, reflecting the rural character and limited housing market.

Geographic Isolation

The name "Leupp" comes from Francis E. Leupp, Commissioner of Indian Affairs from 1905 to 1909. The USPS added this as the primary city name, and it was recognized as a valid mailing address as recently as March 2025. The community's isolation is real. There are no nearby neighborhoods listed in postal records, and the ZIP covers an area larger than many Eastern states' counties.
