Humboldt sits in central Arizona's Yavapai County, about 10 miles east of Prescott. This small community of 1,288 residents has roots in the region's mining boom. Street names like Hecla Street, Azurite Street, Iron King Road, and Calumet Street preserve the area's copper and gold mining heritage that flourished from the 1880s through the mid-20th century.
The Humboldt post office is a PO Box Only Zone. There's no alternative mail delivery across the territory. With 776 PO Boxes serving 500 local households, the post office's reach extends beyond the immediate town. That 1.55x adoption rate means people from surrounding areas without street delivery use this facility as their mail access point.
Most mail arrives via rural carrier routes (238 of 241 street delivery records), fitting the spread-out character of central Arizona. A small number of city carrier routes (2 records) serve the historic town center. General delivery is also available for those without permanent addresses.
The population skews older, with a median age of 48.5 years. About 70% of households own their homes, with a median value of $268,300. Median household income sits at $49,615. Nearly 80% of residents identify as white, with 15% Hispanic or Latino. In September 2020, USPS added "Dewey Humboldt" and "Dewey Humblt" as valid mailing names, recognizing the 2004 incorporation of the combined town of Dewey-Humboldt.
The area has limited commercial activity. Census data shows 21 business establishments employing 90 people across the ZIP. Transportation and warehousing is the largest employment sector, with 298 workers (likely commuting along State Route 69 and Highway 69, both of which pass through town). About 22.5% of workers work from home. Bachelor's degree attainment is 29.4%, slightly below state averages.
The ZIP covers 16.7 square miles of high desert terrain. Street names mix mining history (Mining Claim Trail), natural features (Mingus Mountain Lane, referring to nearby Mingus Mountain), and residential development (Green Valley Way, Lazy River Drive). The community sits between larger Prescott Valley to the north and Prescott to the west, with several Prescott Valley neighborhoods within 4-6 miles.
