Area codes 305 and 786

From Wikipedia, the free encyclopedia

Area code 305 was the single original area code in the state of Florida, and still currently serves all of Miami-Dade County and the part of Monroe County that is in the Florida Keys. The area code is also overlaid by area code 786, but only in Miami-Dade County and not in the Keys portion of Monroe County; the mainland portion of Monroe County is served by area code 239. Due to this overlay, mandatory 10-digit calling is required for the Miami-Dade County portion of the area code, but not for the Florida Keys.^[1]

Area code 305 was originally the default area code for the entire state of Florida.^[2] The western part of the peninsula from the Tampa Bay area south, which was served by non-Bell System telephone companies, was separated into area code 813 in 1953.^[3] As a result of the increase in the state's population, Northern Florida, from the Panhandle to Jacksonville, was assigned area code 904 in 1965, effective Sunday, July 11, 1965 as a flash-cut, with no formal permissive dialing period.^[4] This lasted until 1988 when the east coast of Florida from Palm Beach County north through Brevard County, as well as the Orlando metropolitan area was assigned area code 407.^[5] In 1995 Broward County was split from 305 and assigned area code 954.^[1] In 1998 area code 786 was assigned to relieve the large demand for phone lines in the Miami area.NANP Area Code History: 1998 "Three-Oh-Five" has been the title of many Miami hip-hop songs, and the area code is a pop-culture staple in Miami.
