Historical Timeline of Area Code 321

Area code 321 was created on November 1, 1999, as a split from area code 407 for Brevard County, Florida, while simultaneously overlaying 407 in Orange, Osceola, and Seminole counties. The code was proposed by private citizen Robert 'Ozzie' Osband to represent the NASA countdown sequence ('3-2-1 liftoff') for Kennedy Space Center launches. Governor Jeb Bush placed the first official 321 call on November 1, 1999, from Tallahassee to Kennedy Space Center. Source: Spacey Ideas
