Community Overview

Campo Seco is a tiny rural community in California's Gold Country, tucked into 4.0 square miles of Calaveras County's historic mining territory. With just 48 residents and 16 households, this isn't a border hub despite the automated classification. It's a remnant of California's 19th-century mining boom.

Postal Services

The post office operates as a Community Post Office and maintains 27 PO Boxes for 16 local households, a 1.69 adoption rate that shows the facility serves scattered rural properties beyond the immediate community. Valley Springs, listed as an alias since before 2004, is the larger neighboring town where many Campo Seco residents likely work and shop.

Mining Heritage in Street Names

Street names tell the mining story. Penn Mines Road and Penn Mines Street reference old mining operations. Chileno Way hints at the Chilean miners who worked California's gold fields in the 1850s. Campo Seco itself means "dry field" in Spanish, describing the arid terrain. These 9 streets connect via a single rural carrier route covering the area's 58 residential delivery points.

Demographics

All 16 households are occupied year-round. There are no seasonal vacancies, no group quarters, and no registered businesses in the ZIP. The median age of 43.0 years and mix of 5 owner-occupied and 11 renter-occupied homes suggest a working-age population in modest rural housing.
