Locations for Area Code - 321

Area code 321 serves two regions in Florida: it covers the Space Coast—including cities like Melbourne, Cocoa Beach, and Cape Canaveral—as well as being overlaid in parts of the Orlando metropolitan area. It was introduced in 1999 and uniquely selected for its numerical resemblance to a launch countdown, in homage to the area’s space industry heritage and NASA’s Kennedy Space Center. Ten-digit dialing is required in overlay areas. The 321 code has become a powerful branding tool, linking the region permanently to space exploration and high-tech innovation. It stands as a symbol of Florida’s role in scientific advancement and American aerospace history.
