The 321 area code is one of the area codes for Florida. It was created in 1999 and is currently used to serve Casselberry, Cocoa Beach, and Cape Canaveral. Altamonte Springs, Casselberry, Cocoa Beach, and Cape Canaveral all use the 321 area code as well. The 321 area code also serves parts of Brevard County, Seminole County, Orange County and Osceola County.

Before the creation of the 321 area code, it was home to what is now known as 407/321/689 overlay complex. The reason for this change was due to an increase in demand for phone numbers in those areas that were originally served by 407/321/689 overlay complex.
