The Treasure Coast was served by four different area codes in about a 15-year span. For 41 years the area was part of area code 305, until it became part of area code 407 in 1988. After belonging to NPA 561 since 1996, it finally split off with area code 772 in 2002. 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.
