Community Overview

Cliff spreads across 183 square miles of rural southwestern New Mexico in Grant County. The Gila River flows through this territory, giving the area its agricultural character. With just 481 residents and a median age of 55.2 years, this is an older, quieter community where most people own their homes.

Why PO Boxes Are Required

This is a PO Box Only Zone. There's no street delivery across the entire 183-square-mile territory. The Cliff post office maintains 248 PO Boxes serving 208 households, plus surrounding areas. That's a 1.19 adoption rate, meaning the post office serves not just Cliff itself but ranches and homes scattered across the rural landscape. One rural carrier route and one highway contract route handle the few addresses that qualify for rural delivery.

Rural Road Network

Highway 180 is the main corridor, with 16 delivery points including mobile home spaces and trailer sites. Other roads follow the terrain: Box Canyon Road, Bald Knoll Road, Black Mountain Road. These are country roads serving ranches and rural properties. Spanish names like Sacaton Road and Cienega Drive hint at the area's heritage (19.5% of residents are Hispanic).

Local Character

Median household income sits at $34,167, below the national average. About 37% of homes are mobile homes (97 of 265 total units). Median home value is $198,400. Most residents (85%) own their homes rather than rent. This is working-class rural New Mexico, where people value space and independence over proximity to services.
