The pertinent geography:
Once called Foster's Meadow, and home to the Belmont Race Track, Elmont is a hamlet (an unincorporated area) in the northwest part of the Town of Hempstead, in the west part of Nassau County, along the Nassau/NYC (Queens County) line. There are 36 hamlets (unincorporated areas) and 22 villages (municipal corporations) all or partly within the Town of Hempstead. There are 2 cities and 3 towns in Nassau County. (I'm including after my name a NYS Geographic Glossary with the NYS definitions of county, city, town, village, hamlet and postal zone.)
Beginning on the north and moving in a clockwise direction, the Hamlet of Elmont in the Town of Hempstead is bordered on the north by the Hamlet of Bellerose Terrace, the Village of Floral Park, the Village of South Floral Park and the Village of Stewart Manor; on the east by the Hamlet of Franklin Square; on the south by the Hamlet of North Valley Stream; and, on the west by New York City (the Nassau/Queens County line).

And, as occurs in all but one of Nassau County's 136 communities (2 cities, 64 villages and 70 hamlets), the Hamlet of Elmont has a different border than does the "Elmont, NY 11003" ZIP Code postal zone (i.e., a place can have an "Elmont, NY 11003" mailing address and not be in the Hamlet of Elmont and a place can be in the Hamlet of Elmont and have other than an "Elmont, NY 11003" mailing address).
......Hamlet of Elmont.........2,357
......Elmont, NY 11003........2,791
Thus, a bit more than about 1 in 7 places that have an "Elmont, NY 11003" mailing address are not in the Hamlet of Elmont. Those places that have a "Elmont, NY 11003" mailing address that are not in the Hamlet of Elmont are in the Hamlet of Franklin Square; and, at the same time, there are places in the Hamlet of Elmont that have a "Floral Park, NY 11001" and "Valley Stream, NY 11580" mailing address.
For those who have their copy of the 2010 or earlier edition of the LI Population Survey or have already downloaded the report from the Long Island Power Authority web site (eMail me directly if you need instructions on how to access and download the report), you'll find the Hamlet of Elmont in the Town of Hempstead, Nassau County on pages 5 & 8 (map) and 9 (population estimate).
I hope this information is useful or, at least, interesting.

. Cities, Towns, Villages, Hamlets and Postal Zones in New York State
New York State is divided into counties.
A county is a municipal corporation, a subdivision of the state, created to perform state functions; a "regional" government. All counties are divided into cities, towns and Indian reservations.
A city is a unique governmental entity with its own special charter. Cities are not sub-divided, except into neighborhoods, which are informal geographic areas.
A town is a municipal corporation and encompasses all territory within the state except that within cities or Indian reservations. Towns can be sub-divided into villages and hamlets.
A village is a general purpose municipal corporation formed voluntarily by the residents of an area in one or more towns to provide themselves with municipal services. The pattern of village organization is similar to those of a city. A village is divided into neighborhoods, which are informal geographic areas.
A hamlet is an unincorporated area in one or more towns that is governed at-large by the town(s) it is in. A hamlet is divided into neighborhoods, which are informal geographic areas.
Postal Zone "City" and "Town"
A postal zone "City" and "Town" is an administrative district established by the U.S. Postal Service to deliver the mail. Postal zone "City" and "Town" may not (but are encouraged to) conform to municipal or community borders. Thus, postal zone location does not always determine city, village or hamlet location.
Please be aware: In many areas of New York State, the problem of non-conforming postal zones leads to a situation where the majority of places have a different community name in their mailing address than the community where that place is actually located.
