Packages are piling up in some postal offices in Manhattan and the Bronx because postal carriers can’t get into thousands of apartment buildings, News 4 New York has learned exclusively.

There are 2,000 buildings in the Bronx and 600 more in Manhattan where the United States Postal Service can’t deliver packages because of a limited key-sharing situation: the letter carriers have the key to the building, but when the package carrier arrives, they don’t have the key, the USPS says.
