The community sits in Oswego County along State Route 104, covering 0.349 square miles. With a median age of 45.2, it's home to a mature population in a small rural setting. Most residents here rely on rural carrier delivery, though the post office also handles general delivery service. The facility processes mail for one named building and manages a single street route.
What makes New Haven distinctive isn't its own population but the wider service area it covers. When a post office maintains three boxes for every local household, it's providing essential mail access to people who live well beyond the ZIP code boundaries. These are typically residents of unincorporated areas, farms, and properties on private roads where USPS doesn't offer alternative delivery options.
The ZIP code itself contains minimal infrastructure: one street record for State Route 104 and a single named building called Postmaster. The 14 business establishments and sparse development reflect a rural service area rather than a traditional town center. For dozens of families in the surrounding countryside, this small post office isn't just convenient. It's the only way they receive mail.
The ZIP code contains only State Route 104 in its street delivery records, indicating a highway corridor community with minimal street infrastructure. This single-street pattern is typical of rural postal facilities that serve scattered populations along major transportation routes rather than traditional town grids.
ZIP Code 13121 has 52 residents and 21 households (average 2.48 persons per household). The median age is 45.2 years, older than the state (39.0) and older than the nation (38.8). The gender split is 40.4% male and 59.6% female, which is much lower than the national male share (49.1%), making this a female-majority area. Largest groups are White (71.2%, much higher than the state average of 55.2% and well above the national average of 61.6%) and Hispanic or Latino (3.8%); Hispanic or Latino residents make up 3.8%, which is much lower than the state average (19.5%).
