Area code 772 serves the Treasure Coast of the state of Florida. It covers Sebastian, Fellsmere, Vero Beach, Fort Pierce, Port St. Lucie, Jensen Beach, Stuart, Hobe Sound, Indiantown, and other areas in east central Florida. It was created in 2002 as a split from area code 561 when there was a need for more phone numbers (due in part to the increase of cell phone users).
The region of this code has been under four different area codes in about a 15-year span. It spent 41 years as part of area code 305, until it became part of area code 407 in 1988, then it became part of 561 in 1996, and finally split off into 772 in 2002. Despite the Treasure Coast's rapid growth, 772 is nowhere near exhaustion; under current projections, the region will not need another area code until 2046 at the earliest.
