ZIP code 33101 sits in downtown Miami and operates as a high-volume postal hub rather than a residential neighborhood. Only seven people live here, with a single occupied household, yet the post office maintains 591 PO Boxes. That's an adoption rate of 591.0, meaning this facility serves 591 times more box holders than local residents. This dramatic imbalance reveals the ZIP's true function: providing mail services to businesses, commuters, and people throughout the Miami metropolitan area who need a downtown mailing address.
The ZIP covers just 0.009 square miles in Miami-Dade County, positioned where downtown Miami meets the Overtown neighborhood. Nearly all postal records connect to NW 2nd Avenue, which accounts for 450 of the 451 street delivery records. The street serves commercial buildings with suite and unit designations, including Flagler Station and the Buena Vista Carrier Annex. This isn't a traditional residential street but a spine of downtown business infrastructure.
With 302 business establishments and 790 employees recorded in the area, 33101 functions as a commercial service ZIP rather than a community address. The Hispanic population is significant here, and the facility's location in Miami's urban core makes it accessible to Spanish-speaking residents and businesses throughout the region. Many box holders likely work or own businesses nearby but live in surrounding ZIP codes with standard home delivery.
The post office here doesn't serve a neighborhood in the traditional sense. It serves a city. People drive here from across Miami-Dade County to collect mail, register businesses, or maintain a prestigious downtown address. The single household and seven residents represent caretakers, building managers, or perhaps people living in quarters above commercial spaces. The real population of 33101 shows up during business hours and disappears by evening.
The street pattern here is minimal and purely functional. NW 2nd Avenue dominates with 450 delivery records serving high-rise commercial buildings, while NW 5th Street adds just one record. This isn't a residential grid but a downtown business address. The numbered streets follow Miami's standard grid system, with northwest directionals placing this ZIP in the urban core's commercial zone. Street names don't reveal neighborhood character because there isn't a neighborhood—just a postal hub serving thousands of box holders who work, conduct business, or need a downtown Miami address.
ZIP Code 33101 has 7 residents and 1 households (average 7.00 persons per household). The median age is 50.5 years, significantly older than the state (43.0) and significantly older than the nation (38.8). The gender split is 14.3% male and 85.7% female, which is much lower than the national male share (49.1%), making this a female-majority area. Largest groups are Hispanic or Latino (57.1%) and Black or African American (28.6%, much higher than the state average of 15.1% and well above the national average of 12.4%); Hispanic or Latino residents make up 57.1%, which is much higher than the national average (18.7%), and Black or African American share is much higher than both the state (15.1%) and national averages (12.4%).
