A Town on the International Boundary

Naco sits directly on the U.S.-Mexico border in southeastern Arizona, just 8 miles south of Bisbee. The town shares its name with Naco, Sonora, its Mexican sister city. With 734 residents and 229 occupied homes, this is a small border community where daily life often crosses the international line.

Why Everyone Uses a PO Box

The post office maintains 553 PO Boxes for a community of just 229 households. That's 2.4 boxes per household, making Naco a true PO Box Only Zone with no alternative mail delivery available. Residents from across the surrounding area depend on this post office since there isn't any street delivery. The rural and city routes that exist serve a handful of addresses, but most people pick up their mail at the post office.

A Binational Community

Only 14% of Naco's residents were born in the United States. This isn't surprising for a border town where families have roots on both sides. Street names tell the story: Dominguez, Valenzuela, Martinez, Rodriguez, Valencia, and Acuna. These are family names, not subdivisions designed by a developer.

Border Economy

Naco's economy has a distinct pattern. About 264 workers are in transportation, warehousing, and utilities, likely connected to cross-border commerce and the port of entry. Another 60 work in public administration, with 35 specifically federal employees. Border Patrol and Customs are major employers here. Mobile homes account for 44% of housing stock, with median home values at $74,000.

Demographics

The median household income of $51,161 sits close to the national median, though per capita income of $18,143 reflects larger households (3.2 people per household on average). Median age is 33.8, younger than most Arizona communities, suggesting working families rather than retirees.

Street Name Patterns

Spanish Surnames Historic Family Names
