The five boroughs by ZIP code count
Manhattan carries by far the most ZIP codes of any borough, not because it's the most populous (Brooklyn and Queens both have more residents) but because Manhattan's dense mix of office buildings, large employers, and high-rise residential blocks gets subdivided into more, smaller ZIP delivery areas.
NYC boroughs, their ZIP code counts, and the county each one is legally identical to
| Borough | County | ZIP codes | Range |
|---|---|---|---|
| Manhattan | New York County | 146 | 10001-10286 |
| Queens | Queens County | 79 | 11004-11697 |
| Brooklyn | Kings County | 47 | 11201-11256 |
| The Bronx | Bronx County | 25 | 10451-10475 |
| Staten Island | Richmond County | 14 | 10301-10314 |
Queens is the exception: its ZIP codes never say "Queens"
Ask for a Brooklyn ZIP code and USPS calls it "Brooklyn." Ask for a Staten Island ZIP and it's "Staten Island." Queens breaks that pattern entirely. Every one of its 79 ZIP codes is addressed by an older, more local place name instead: Astoria, Long Island City, Flushing, Jamaica, Forest Hills, Rockaway Park, and 35 others. "Queens" itself never appears as a USPS place name.
The most commonly cited explanation goes back to 1898: Queens was consolidated that year from a patchwork of existing towns and villages that already had their own post offices, and many of those names stuck instead of being replaced by the new borough name. That's not the full story, though. Staten Island's five original towns (Castleton, Middletown, Northfield, Southfield, and Westfield) were folded into the city in that very same 1898 merger, yet Staten Island addresses use the single borough name today, not those old town names. And not every Queens place name even predates 1898: Bellerose, for instance, was coined as a new development name in the early 1900s, well after consolidation. Brooklyn, by contrast, had already unified its post offices under "Brooklyn" before 1898, so that name stuck there without the same complication.
Manhattan, Brooklyn, the Bronx, and Staten Island line up exactly with their counties
New York City is unusual among major US cities in that each of its boroughs is legally identical to a county: Manhattan is New York County, Brooklyn is Kings County, the Bronx is Bronx County, and Staten Island is Richmond County. That means every ZIP code in one of these four boroughs sits entirely within a single, named county, with no cross-county splits the way Atlanta splits between Fulton and DeKalb or Chicago's near suburbs sometimes have.
