Cities in area code 321

By numbering footprint the leading localities are Cocoa, Melbourne, Orlando, Eau Gallie, Titusville, Cocoa Beach, Winter Park and Sanford, and 12 smaller communities down to single-prefix localities. Prefix counts track lines in service, so the ranking is a reasonable proxy for where the code's subscribers actually are.

Overlap note: 16 localities are shared with other area codes, so a neighbor's number may differ in its first three digits.
Clock-wise the coverage is Eastern.
A caller's real location can differ: numbers port between carriers and follow their owners when they move. Use the prefix tables to see where a specific number block was issued.
