For those who may not be familiar with East Hills:
East Hills is a village (incorporated in 1931) partly in the central-east part of the Town of North Hempstead and partly in the northwest part of the Town of Oyster Bay, in the north-central part of Nassau County.
Beginning on the north and moving in a clockwise direction, the Village of East Hills in the Towns of North Hempstead and Oyster Bay is bordered on the north by the Village of Roslyn Harbor in the Town of North Hempstead and the Hamlet of Greenvale in the Towns of North Hempstead and Oyster Bay; on the east by the Village of Brookville and the Village of Old Westbury in the Town of Oyster Bay; on the south by the Hamlet of Roslyn Heights in the Town of North Hempstead; and, on the west by the Hamlet of Roslyn Heights and the Village of Roslyn in the Town of North Hempstead.
East Hills is one of those many villages and hamlets on Long Island where none of the places in the community have the village name in their mailing address: places in the Village of East Hills have a "Roslyn, NY 11576", "Roslyn Heights, NY 11577", "Greenvale, NY 11548" and "Old Westbury, NY 11568" mailing address.
