You need to be aware that Roslyn is one of those many villages and hamlets on Long Island where the majority of the places with the community name as part of their mailing address (3,496 acres) are not in the community (381 acres):
Places that have a "Roslyn, NY 11576" mailing address that are not in the Village of Roslyn are in the Village of Roslyn Harbor, the Village of East Hills, the Hamlet of Roslyn Heights, the Village of Roslyn Estates, the Hamlet of Searingtown, the Village of North Hills, the Village of Flower Hill and the Village of Old Westbury; and, at the same time, there are places in the Village of Roslyn with a "Roslyn Heights, NY 11577" mailing address.
Also, complicating the matter even more, the "Roslyn, NY 11576" ZIP Code postal zone is a bifurcated postal zone, with two noncontiguous areas separated by the "Roslyn Heights, NY 11577", the "Albertson, NY 11507" and the "Manhasset, NY 11030" ZIP Code postal zones.
You can find out in which community (city, village or CDP) your work is actually located, which is oftentimes different from the community named in that place's mailing address, by using the Census Bureau's
online address search function. (CDP, or
Census
Designated
Place, is the Census Bureau equivalent for a hamlet in Nassau and Suffolk Counties.)
