The Space Coast is a region in the U.S. state of Florida around Kennedy Space Center, where the U.S. Air Force and NASA frequently launch rockets and shuttles into space. Cities in the area include Titusville, Cocoa, Merritt Island (unincorporated), Cocoa Beach, Melbourne and Palm Bay; and most of the area lies within Brevard County.It is bounded on the south by the Treasure Coast. It is not only bounded on the west and north by the Central Florida region, it is often included in that region, as well. It is bounded on the east by the Atlantic Ocean.
Once the area became too large to be served by one area code, a local resident discovered that area code 321 was not assigned to any other territory (though it was being considered for the suburban Chicago area).If said "3, 2, 1" it resembles the countdown before liftoff; thus, the resident petitioned for the code to be assigned to the Space Coast region. His efforts were popular among local residents and resulted in success; the new code became effective on November 1, 1999.
