Glenwood Landing is a small waterfront community on Long Island's North Shore in Nassau County. Despite being located in one of New York's most developed suburban counties, this 0.46 square mile hamlet has no street delivery. All 995 residents receive mail exclusively through PO Boxes.
The Glenwood Landing post office maintains 467 PO Boxes serving 356 local households, an adoption rate of 131%. This means the post office serves not just local residents but also people from surrounding communities. With median home values of $916,700 and household incomes of $123,452, Glenwood Landing is one of the more affluent communities with PO Box-only service.
Mail delivery uses a mixed pattern. The post office operates one city carrier route and one rural route covering 30 streets. Glenwood Road, the main thoroughfare with 25 delivery records, includes multi-floor buildings. Shore Road, with 9 records including penthouse and unit designators, confirms the waterfront character. Street names like Landing Court and the hamlet's name itself reference its historic role as a waterfront landing point.
This isn't a remote or undeveloped area. Glenwood Landing sits among affluent North Shore communities including Sea Cliff, Roslyn Harbor, and Glen Head, all within a mile. The population is highly educated (59% hold bachelor's degrees or higher) and established, with 84% of housing units owner-occupied. The median age of 43.4 years indicates working families rather than retirees. Only 6 of 383 housing units are seasonal, so this is a year-round residential community.
The PO Box classification dates to before October 2004, when tracking began, making it a legacy designation. USPS added an abbreviated alias, "Glenwood Lndg," in May 2005 to accommodate the lengthy primary name. For mailing purposes, both "Glenwood Landing" and "Glenwood Lndg" are acceptable.
Street names combine waterfront references (Shore Rd, Landing Ct) with nature themes (Grove, Walnut, Maple) and a partial numbered grid (1st, 2nd, 3rd Streets), typical of historic Long Island hamlets.
ZIP Code 11547 has 995 residents and 356 households (average 2.79 persons per household). The median age is 43.4 years, older than the state (39.0) and older than the nation (38.8). The gender split is 48.7% male and 51.3% female, which is about the same as the state male share (48.4%), making this a female-majority area. Largest groups are White (82.9%, much higher than the state average of 55.2% and well above the national average of 61.6%) and Asian (8.2%, slightly higher than the national average of 6.0%); Hispanic or Latino residents make up 6.9%, which is much lower than the state average (19.5%).
