Queensbury, New York relies primarily on the 12804 postal code, which covers the majority of the town within Warren County. While 12804 is the core identifier for residents and local businesses, neighboring codes like 12801 (Glens Falls), 12820 (Cleverdale), 12839 (Hudson Falls), and 12844 (Kattskill Bay) overlap parts of the municipal boundaries or serve specific lakeside and rural pockets.
Navigating postal boundaries in this region matters because mail delivery, utility zoning, and emergency services depend heavily on exact designations. Whether you're moving to the area, setting up local logistics, or verifying real estate boundaries, understanding how these codes split up the town saves you from costly mailing errors or logistical mix-ups.

Overlapping and Neighboring Codes
Because municipal borders don't always align neatly with postal service routes, several surrounding zip codes dip into the town limits or serve postal boxes tied directly to Queensbury addresses.
- 12801 (Glens Falls): Covers southern fringes bordering the city of Glens Falls, where properties often share commercial and residential proximity.
- 12820 (Cleverdale): Serves specific waterfront and seasonal properties along the eastern shore of Lake George within the town's broader sphere.
- 12839 (Hudson Falls): Reaches into southeastern sections near the Washington County border.
- 12844 (Kattskill Bay): Handles mail for properties located further north along the lake.
If you're buying real estate or verifying a shipping address, don't rely solely on municipal maps. Always check the physical parcel against the official USPS Zip Code Lookup tool to confirm whether a location requires the standard Queensbury designation or an adjacent postal city.
Common Mistakes with Queensbury Addresses
Mixing up regional postal zones is easy, especially for newcomers accustomed to grid-based city layouts. Here are a few pitfalls to avoid:
- Assuming a single code covers everything: While 12804 handles the bulk of the town, lakefront and rural properties frequently require specific PO boxes or neighboring town codes.
- Confusing Glens Falls and Queensbury mailing names: Because the two municipalities sit right next to each other, postal carriers often accept interchangeable city names for border-adjacent streets, but automated sorting systems prefer exact matches.
- Ignoring seasonal delivery quirks: Properties situated near Lake George may experience distinct seasonal mail delivery adjustments, particularly for summer-only residences using specialized box codes.
