Area code 321 serves two distinct roles in Florida. As an overlay, it serves the Orlando metro alongside 407 and 689, while it also uniquely serves the **Space Coast** region—including Cape Canaveral, Melbourne, and Titusville—as a standalone code. Established in 1999, the number ‘321’ was deliberately chosen to reflect a rocket launch countdown, in homage to the area's deep ties to NASA and the Kennedy Space Center. The Space Coast is vital to the U.S. space program and continues to grow with private aerospace companies like SpaceX and Blue Origin. In Orlando, 321 supports the booming tourism and tech sectors. This dual-purpose code symbolizes Florida’s leadership in both tourism and space innovation, making it one of the most distinctive area codes in the U.S.
