Beginning on its northern border and proceeding clockwise, East Garden City was bordered on the north by Carle Place and the Village of Westbury in the Town of North Hempstead (the Hempstead/North Hempstead town line); on the east by East Meadow; on the south by Uniondale and the Village of Hempstead; and, on the west by the Villages of Hempstead and Garden City.
East Garden City was one of many areas on Long Island where none of the places in the community have the hamlet name as part of their mailing address: places in East Garden City have either a "Garden City, NY 11530", a "Westbury, NY 11590", a "Uniondale, NY 11553" or a "Hempstead, NY 11550" mailing address.
In 2015, there were disputes between Uniondale and East Garden City about the latter's existence.
According to the Long Island Press,[3] "They [civic leaders from Uniondale] argue that planners and developers concocted the name to distance prime real estate north of Hempstead Turnpike from the racially diverse neighborhood on the south side. Lawmakers back Uniondale’s cause, but wiping East Garden City off the map is easier said than done. At stake is what to call the heart of the area also known as the Nassau Hub—home to almost half the county’s economic activity and Nassau Veterans Memorial Coliseum."
Newsday later notes, "In May [2015], the controversy led to a meeting involving then-Town Supervisor Kate Murray, Rep. Kathleen Rice (D-Garden City) and federal census officials, who, while agreeing to drop the name, indicated it might take 18 months to become official."[4]
