Area code 321
Area code 321 is the area code serving Brevard County, Florida, Space Coast Region and Seminole County, Florida. The area code has been in use since November 1, 1999; it was assigned to Florida after a successful petition led by local resident Robert Osband to commemorate the Space Coast's impact on Brevard County. The code refers to the countdown sequence which has launched many spacecraft from Cape Canaveral.
When it was activated in 2000, area code 321 was used as an overlay for most of area code 407 in the Orlando area, except for the small portion of Volusia County that includes Deltona which was in 407 at the time. However, no 321 numbers were issued in the 407 area from 2003 until 2015, when 321 numbers were issued for cell phones in Osceola, Orange, and Seminole counties due to high demand. With the 407/689 overlay, 321 remains frozen in the Orlando area with new 321 numbers again being assigned only in Brevard County. 10-digit local calling remains mandatory.
Area code 321 is also the NPA used for SatCom Satellite Phone units. Harris/Caprock Corporation has maritime satellite calls going through its corporate call center in Melbourne.
