History & Geography of Area Code 305

Area code 305 was among the original 86 area codes implemented in October 1947 under the North American Numbering Plan Administrator Wikipedia Initially covering the entire state of Florida, it split off area code 813 in 1953 and later spawned 904 (1965), 407 (1988), and 954 (1995), before being completely overlaid by 786 in 2008 Wikipedia Wikipedia To address ongoing number exhaustion, area code 645 was activated on August 4 2023 in the same numbering plan area Wikipedia Axios

Today, 305—renowned worldwide thanks to Miami’s cultural exports—serves all of Miami-Dade County, from Downtown to Coral Gables, and extends to the Florida Keys Aircall Its distinct status conveys instant local authenticity and remains one of the most coveted prefixes in telecommunications.

Due to its overlay structure with 786 and 645, mandatory ten-digit dialing is required for all calls within the region, ensuring seamless number assignment without disrupting existing subscribers Florida PSC
