The postal infrastructure here reflects the community's mixed delivery character. While the ZIP has one city carrier route serving Carr Principal (the main road), most residents rely on PO Boxes for their mail. This pattern is common in Puerto Rico's interior communities, where winding mountain roads and dispersed settlement patterns make PO Boxes a practical choice even when street delivery technically exists. The median household income of $18,295 and median home value of $102,900 show this is a working-class rural community where postal accessibility matters for daily life.
Only Carr Principal appears in postal records, reflecting the area's rural character with delivery concentrated along the main road while most residents use PO Boxes.
