For those who may not be familiar with Manorville:
Manorville is a hamlet (an unincorporated area) in the northeast section of the Town of Brookhaven, in the middle of Suffolk County, along the Brookhaven/Riverhead town line.
Beginning on the north and moving in a clockwise direction, the Hamlet of Manorville in the Town of Brookhaven is bordered on the north by the Hamlet of Calverton in the Town of Riverhead (the Brookhaven/Riverhead town line); on the east by the Hamlet of Calverton and the Hamlet of Eastport; on the south by the Hamlet of East Moriches, the Hamlet of Center Moriches, the Hamlet of Moriches and the Hamlet of Mastic; and, on the west by the Hamlet of Mastic, the Hamlet of Shirley and the Hamlet of Yaphank (Brookhaven National Laboratory).
The Hamlet of Manorville has a different border than does the "Manorville, NY 11949" postal zone (i.e., a place can have a "Manorville, NY 11949" mailing address and not be in the Hamlet of Manorville and a place can have other than a "Manorville, NY 11949" mailing address and be in the Hamlet of Manorville): places that have a "Manorville, NY 11949" mailing address that are not in the Hamlet of Manorville are in the Hamlet of Calverton, Town of Riverhead; and, at the same time, there are places in the Hamlet of Manorville with a "Mastic, NY 11950" and an "East Moriches, NY 11940" mailing address.
