Area code 321 is an area code in the North American Numbering Plan (NANP) for Brevard and Seminole counties, and the Space Coast region in the U.S. state of Florida. The area code was activated in 2000, as an overlay for the Orlando area.

321 was used in Orlando area with an overlay area code 407 and exception for a small portion of Volusia County that includes Deltona which was in 407 at the time (it is now in 386). 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.
Area code 321 is also used for SatCom Satellite Phone units. [1] Harris/Caprock Corporation has maritime satellite calls going through its corporate call center in Melbourne.
Prior to October 2021, the area code had telephone numbers assigned for the central office code 988, which created conflicts given the designation of 988 as a three-digit code for the National Suicide Prevention Lifeline. In 2020, the Federal Communications Commission ordered 82 area codes to transition to ten-digit dialing, including 321, in the area not overlaid by 407. Per the timeline set by the North American Numbering Plan Administrator (NANPA), permissive dialing began on April 24, 2021, and 10-digit dialing was required on October 24, 2021. [2]
American Space Museum volunteer Robert Osband petitioned the creation of area code 321. [3] The code refers to the countdown sequence which has launched many spacecraft from Cape Canaveral. [4] [5] [6]
