For those who may not be familiar with Glen Cove:
Glen Cove is one of two cities (Long Beach is the other city) in Nassau County and is located in the north central part of Nassau County.
Glen Cove incorporated as a city in 1918 and became independent of the Town of Oyster Bay. Prior to that date, Glen Cove was a hamlet (unincorporated area) in the Town of Oyster Bay, initially in Queens County until January 1, 1899, and since then in Nassau County. Before it was called Glen Cove, the hamlet was called Musketa Cove.
Beginning on the north and moving in a clockwise direction, the City of Glen Cove is bordered on the north by Long Island Sound; on the east by the Village of Lattingtown and the Village of Matinecock in the Town of Oyster Bay; on the south by the Hamlet of Glen Head and the Village of Sea Cliff in the Town of Oyster Bay; and, on the west by Long Island Sound.
The City of Glen Cove has a different border than does the "Glen Cove, NY 11542" postal zone (i.e., a place can have a "Glen Cove, NY 11542" mailing address and not be in the City of Glen Cove): places that have a "Glen Cove, NY 11542" mailing address that are not in the City of Glen Cove are in the Village of Lattingtown (incorporated in 1931) and the Village of Matinecock (incorporated in 1928) in the Town of Oyster Bay.
