Reported last February that:
Another case of Roosevelt Island being jurisdictionally part of Manhattan but not considered so by the rest of the world. Amazon Prime Now started it's one hour delivery service for Manhattan but not to Roosevelt Island's 10044 Manhattan zip code....Amazon Prime Now delivery service is now available for Roosevelt Island.
Last week we added delivery to Roosevelt Island (10044). No need to hop on the tram, we'll come to you! http://t.co/7rY9Oq6xZf— Amazon Prime Now (@amazonprimenow) June 23, 2015
