Rillito is a small unincorporated community in Pima County, Arizona, covering just 0.26 square miles along the edge of the greater Tucson metro area. With 94 residents and 42 households, this isn't a large community. But the post office serves a much wider area. The Rillito post office maintains 102 PO Boxes for a local population of just 42 households, creating an adoption rate of 2.43. That means the post office handles mail for more than twice as many recipients as there are local homes.
This is a PO Box Only Zone. There's no alternative mail delivery across the service area. While the ZIP includes one rural carrier route and one highway contract route covering 27 street addresses, the overwhelming majority of mail recipients rely on PO Boxes. Rural delivery routes in this region often serve scattered properties without traditional street addressing, making PO Box service the practical solution.
The community's 6 business establishments employ 316 workers, far exceeding the residential population of 94. This pattern is typical for small unincorporated areas that function as service points for surrounding regions. Workers commute in, businesses maintain PO Boxes for commercial mail, and nearby residents without home delivery use Rillito as their postal address.
Rillito sits in the northern Tucson metro area, near neighborhoods like Rillito Vista, Milligan's Acres, and Happy Acres. The area has a median age of 43.5 years and a diverse population. Of the 94 residents, 41 are White, 25 are Black or African American, and 11 identify as Hispanic or Latino. Housing is split between 25 owner-occupied and 17 renter-occupied units. The compact 0.26 square mile territory includes streets like N Casa Grande Highway, N David Avenue, and W Campbell Street, many with UNIT designations indicating multi-unit properties.
The high ratio of PO Boxes to households makes Rillito a regional mail access point. People from the surrounding unincorporated areas rely on this post office because it's their designated delivery location. This service pattern reflects the reality of outer metro areas where rural character meets suburban sprawl, and traditional home delivery infrastructure doesn't extend to every property.
Mail should be addressed to PO Box numbers with RILLITO, AZ 85654 as the last line. While some street addresses exist on rural and highway routes, PO Box delivery is the standard service for this community.
Most streets have UNIT designations indicating multi-unit properties, with N Casa Grande Highway serving as the main corridor.
