The numbering plan area (NPA) includes Sebastian, Fellsmere, Vero Beach, Fort Pierce, Port St. Lucie, Jensen Beach, Stuart, Hobe Sound, Indiantown, and other areas in east central Florida.
The area code was created in 2002 in a split from area code 561, when the telephone number pool exhausted due in part to the increase of cell phone users.
The Treasure Coast was served by four different area codes in about a 15-year span.
Today, despite the Treasure Coast's rapid growth, 772 is nowhere near exhaustion; NANP projections estimate that the region will not need another area code until at least 2069.
In pop-culture, this area code is referenced in YNW Melly’s 772 Love.
