Area Code "321" Details & History:
Area code 321 is the area code serving Brevard County, Florida. It has been in use since November 1, 1999, and was assigned to the area after a successful petition drive due to the Space Coast's impact on the county (if pronounced properly – 3, 2, 1 – the code resembles the countdown which launches the many spacecraft from Cape Canaveral). Part of 321 also overlays area code 407 in the Orlando area. This is currently the only area code in North America that is both the overlay of one established area code, but also the primary area code of another. Florida area code 321 has been in service since 1999. It has 230 landlines and 87 wireless prefixes (exchanges) serviced by 44 carriers. It covers 4 counties, 387 ZIP codes, and 39 cities, including Melbourne, Palm Bay, Cocoa, Titusville, Merritt Island, Rockledge, Cocoa Beach, Satellite Beach, and Cape Canaveral.
