Manhattan’s dedicated ZIP codes

Some Manhattan buildings have their own five-digit ZIP code when mail volume or delivery needs cannot be handled adequately by a ZIP+4 code. But the figure “43” is outdated: in 2019, a USPS spokesperson said 41 Manhattan buildings had their own ZIP codes. That count does not cover every unique ZIP code used by agencies, universities, or post-office boxes; a ZIP code describes mail delivery and does not necessarily mark a building’s geographic boundary.
