Finding the right postal code in Kings County can feel complicated because neighborhood lines rarely match up neatly with postal boundaries. Brooklyn uses dozens of active postal codes starting with the prefix 112, spanning from the historic brownstones of Brooklyn Heights out to the quiet residential blocks of Canarsie. Whether you're filling out shipping forms, buying property, or trying to understand local municipal boundaries, knowing how these zones work saves time and prevents delivery errors.
Every address in the borough sits within a specific delivery zone managed by the United States Postal Service. Understanding these numerical boundaries helps you navigate local real estate markets, target local marketing efforts, or simply figure out which subway station serves a particular street. Let's break down how the system is organized, which codes cover major neighborhoods, and how to verify any address quickly.
How Brooklyn Postal Codes Are Structured
Postal zones in New York City follow a specific geographical logic. While Manhattan codes begin with 100, 101, or 102, and Queens codes start with 113, 114, or 116, every single standard address in Brooklyn starts with 112.
The remaining two digits generally correlate with the historical postal zones established back in 1943 before the modern five-digit system rolled out nationally in 1963. For instance, old Zone 17 became 11217, covering parts of Park Slope and Boerum Hill, while Zone 4 became 11204, covering Bensonhurst.
The numerical sequence generally moves outward from the waterfront civic center. The lowest standard residential code is 11201, covering Downtown Brooklyn, DUMBO, and Brooklyn Heights. From there, the numbers fan out across central, southern, and eastern Kings County, scaling up to codes like 11236 in Canarsie and 11239 in Starrett City.
You'll also notice a few specialized codes that don't represent traditional residential neighborhoods. For example, 11251 is assigned strictly to the Brooklyn Navy Yard, and 11252 belongs to the Fort Hamilton military base. Other high-end numbers like 11241 or 11243 are designated for specific institutional or high-volume business P.O. boxes rather than street delivery routes.
Major Neighborhoods and Their Postal Codes
Because multiple codes often overlap a single neighborhood—or conversely, one code stretches across multiple communities—it helps to look at the primary residential hubs individually.
Downtown and the Waterfront
- 11201: Covers Brooklyn Heights, Downtown Brooklyn, DUMBO, Vinegar Hill, and parts of Boerum Hill. This zone features high-rise residential towers mixed with historic landmark districts right by the East River bridges.
- 11205: Encompasses Clinton Hill, Fort Greene, and the western edge of Bedford-Stuyvesant, bordering the Navy Yard.
- 11231: Serves Carroll Gardens, Red Hook, and the Columbia Street Waterfront, known for low-rise brick townhouses and active maritime commercial spaces.
North and East Brooklyn
- 11211 and 11249: These two zones cover Williamsburg. While 11211 captures the inland and southern sections, the waterfront strip along Kent and Wythe avenues was designated as 11249 to handle the massive influx of high-density residential development.
- 11206 and 11237: Span across East Williamsburg and parts of Bushwick, areas characterized by converted industrial warehouses, loft apartments, and dense multi-family housing.
- 11222: Covers Greenpoint, Brooklyn's northernmost neighborhood nestled against Newtown Creek.
Central Brooklyn and Park Slopes
- 11215 and 11217: These codes anchor Park Slope, Gowanus, and Windsor Terrace. Code 11217 stretches north toward Prospect Heights, while 11215 handles the southern slopes leading down toward Green-Wood Cemetery.
- 11213, 11216, 11225, 11233, and 11238: These numbers divide the expansive communities of Bedford-Stuyvesant, Crown Heights, and Prospect Lefferts Gardens. Real estate prices and architectural styles vary drastically from block to block within these zones.
- 11226: Covers Flatbush and Prospect Park South, famous for its grand standalone Victorian homes and large apartment complexes.
South and Southwest Brooklyn
- 11209: Dedicated to Bay Ridge, sitting tightly against the Narrows and the Verrazzano-Narrows Bridge.
- 11204, 11214, and 11228: Serve Bensonhurst, Bath Beach, and Dyker Heights, regions widely known for suburban-style detached homes, multi-family brick houses, and famous neighborhood holiday light displays.
- 11219 and 11230: Handle Borough Park and Midwood, dense residential communities with vibrant commercial corridors.
- 11224 and 11235: Cover the southern coastal communities of Coney Island, Brighton Beach, and Manhattan Beach, opening directly onto the Atlantic Ocean.
Common Mistakes to Avoid When Using Local Postal Codes
People frequently run into delivery delays or administrative mix-ups because of a few common assumptions about New York geography.
- Don't confuse city name with borough: For municipal mail, writing "Brooklyn, NY" is completely correct and preferred over writing "New York, NY" for addresses in Kings County. Using Manhattan's city designation for a Brooklyn address can route mail through sorting facilities incorrectly.
- Watch out for shared border streets: Properties right on the edge of two postal zones often get mislabeled. Always verify the specific block range rather than guessing based on the general neighborhood name.
- Account for new developments: Waterfront sectors and massive multi-use conversions often get assigned brand-new codes or split off from older ones as population density shifts. If you're managing logistics for a new construction project, check the official database provided by the USPS Business Customer Gateway rather than relying on outdated map books.
Frequently Asked Questions
What is the lowest and highest postal code in Brooklyn?
The lowest standard residential code is 11201 (Brooklyn Heights/Downtown), while the highest overall numerical code assigned to a facility in the county is 11256.
Does a single neighborhood ever have multiple postal codes?
Yes. Large neighborhoods like Bedford-Stuyvesant, Flatbush, and Williamsburg span across three or four different codes to manage mail volume efficiently.
How can I find the correct code for a specific street address?
You can look up any exact street location using the Look Up a ZIP Code tool on the official USPS website. Entering the house number and street name will instantly return the precise five-digit code and corresponding four-digit extension (ZIP+4).
Why do some buildings have their own unique codes?
Large commercial complexes, government facilities, and institutional campuses—such as the Brooklyn Navy Yard or specific federal properties—receive unique codes because they generate enough daily mail volume to warrant dedicated routing independent of surrounding residential streets.
