Mail delivery reflects the base's institutional nature. Instead of street addresses, the ZIP maintains building-based delivery through named facilities. NAVAL STATION MAYPORT handles the most delivery points, followed by individual buildings like NAVSTA MAYPORT and NAS MAYPORT. The post office uses what USPS calls "firm" addresses, where mail goes to specific buildings rather than traditional street numbers. Only three streets appear in delivery records: NAVAL STATION MAYPORT (which handles 8 different delivery points), BANCOLLS, and MASSEY AVE.
The demographics confirm this is a military population. Median age sits at 23.2 years, typical for active-duty enlisted personnel. Of the 219 residents, 184 live in non-institutionalized group quarters: barracks, shipboard berthing, and base housing specifically for service members. Only 1 occupied housing unit exists in traditional census terms, because military barracks don't count as "households" in civilian demographic data.
Naval Station Mayport operates as one of the Navy's major East Coast installations, home to multiple guided-missile destroyers and cruisers. The base occupies just 0.25 square miles on the north bank of the St. Johns River, near where the river meets the Atlantic. The ZIP's geographic footprint matches the base boundary precisely. Civilian delivery exists in surrounding neighborhoods, but those addresses fall under different Jacksonville ZIP codes. Here, every piece of mail goes through military channels to base facilities.
The base maintains 95 businesses on site, ranging from the commissary and Navy Exchange to ship repair facilities and administrative offices. These businesses employ 511 people according to census records, though many work on the ships homeported here rather than in fixed shore facilities. Median household income registers at $32,486, reflecting junior enlisted pay scales. The 5 residents working from home likely represent civilians living in on-base quarters or officers handling administrative duties remotely.
Street delivery is minimal because Naval Station Mayport uses building-based addressing. NAVAL STATION MAYPORT dominates with 8 delivery points, while BANCOLLS and MASSEY AVE represent limited street addresses on the installation.
