Mesilla sits just south of Las Cruces in New Mexico's Rio Grande valley. This historic village of 718 residents preserves its Spanish colonial character through street names like Calle de Parian, Calle de Guadalupe, and Calle Principal. Founded in 1848, Mesilla briefly served as the Confederate territorial capital of Arizona and New Mexico during the Civil War. Today it's known for its preserved adobe architecture and plaza.
The Mesilla post office maintains 767 PO Boxes for 332 local households. That's a 2.31x adoption rate, meaning the post office serves more than twice as many boxes as there are homes in the village. This high ratio shows Mesilla's role as a regional mail hub serving surrounding unincorporated areas, businesses on the plaza, and second homeowners. The village is designated a PO Box Only Zone, so there's no alternative carrier delivery across the 0.67 square mile territory.
Mesilla has an older, educated population. Median age is 52.7 years, with only 7 residents under 18 and 18% age 65 or older. Education levels are high for a small New Mexico village: 42.4% of adults hold bachelor's degrees or higher. Median household income is $66,300, and median home values reach $253,000, both well above typical rural New Mexico figures.
The village's Spanish heritage appears throughout the street grid. Calle de Parian (the main commercial street around the plaza) accounts for 116 ZIP+4 records, more than half of all street delivery points. Other streets honor Catholic saints (Calle de San Albino, Calle de Santa Ana) and Spanish colonial urban planning (Calle del Norte, Calle del Sur). Many addresses include unit numbers, showing adaptive reuse of historic buildings as apartments and commercial spaces.
Mesilla's delivery pattern mixes urban and rural routes. One city carrier route (C) and one rural route (R) serve the village streets, with a highway contract route (H) and general delivery also available. This mixed system is typical for historic village cores surrounded by agricultural land. The post office operates from a facility coded "P" for Post Office, with no city delivery indicator, reinforcing the PO Box dependency.
All mail must use PO Box addresses. This isn't a limitation but rather the standard for this historic community. The post office serves as a gathering point where residents and business owners collect mail, continuing a tradition that dates back more than 150 years.
All streets use Spanish colonial naming conventions honoring saints, directions, and historic features of the village plaza.
