A map showing Huntington and the surrounding communities may be of some help to you in getting am understanding of the area:
But, first, it is important to know that there are 3 "Huntingtons" (from smallest to largest, in order of acreage):
1. There is the Hamlet of Huntington (whose "downtown" commercial district is colloquially referred to as Huntington Village);
2. There is the "Huntington, NY 11743" ZIP Code postal zone, and it includes the Hamlet of Huntington and parts of 2 villages (municipal corporations) and 6 hamlets (unincorporated areas) within its service area; and,
3. There is the Town of Huntington, and it includes 4 villages and 15 hamlets as well as the "Huntington, NY 11743" ZIP Code postal zone and all or parts of 11 other ZIP Code postal zones, within its borders.
And now, second, for those who may not be familiar with Huntington:
Huntington is a hamlet (an unincorporated area) in the north part of the Town of Huntington, in the northwest part of Suffolk County.
Beginning on the north and moving in a clockwise direction, the Hamlet of Huntington in the Town of Huntington is bordered on the north by Huntington Harbor, the Hamlet of Halesite, the Village of Huntington Bay, Huntington Bay and the Hamlet of Centerport; on the east by the Hamlet of Centerport and the Hamlet of Greenlawn; on the south by the Hamlet of Huntington Station; and, on the west by the Hamlet of Cold Spring Harbor and the Village of Lloyd Harbor.
The Hamlet of Huntington has a different border than does the "Huntington, NY 11743" ZIP Code postal zone (i.e., a place can have a "Huntington, NY 11743" mailing address and not be in the Hamlet of Huntington and a place can have other than a "Huntington, NY 11743" mailing address and be in the Hamlet of Huntington): places that have a "Huntington, NY 11743" mailing address that are not in the Hamlet of Huntington are in the Hamlet of West Hills, the Hamlet of Halesite, the Village of Huntington Bay, the Village of Lloyd Harbor, the Hamlet of Centerport, the Hamlet of Greenlawn and the Hamlet of Elwood; and, at the same time, there are places in the Hamlet of Huntington with a "Huntington Station, NY 11746" and a "Greenlawn, NY 11740" mailing address.
