Area code 786 is an overlay for 305, covering Miami-Dade County and parts of the Florida Keys. Introduced in 1998, it supports the heavy demand in one of the country’s most vibrant and multicultural urban areas. Miami is known globally for its Latin American influence, international banking, nightlife, and tourism. Ten-digit dialing is mandatory. While 305 is iconic and historic, 786 has become equally common, especially among newer mobile numbers. Together, the two codes define Miami’s energetic, global, and fast-moving environment.
