The 305 area code is an area code for the olden state of Florida. It serves as the telephone numbering plan code for the most populous county in the state, Miami-Dade. This area code works as part of the North American Numbering Plan (NANP) which is a system of numbering and allocation of phone numbers to the public switched telephone network in the United States, as well as its dependencies. It had a split at some point with part that was used to form the 786 and 754 area codes in 1998, with more landline and wireless numbers being created by the 754 area code in 2000.
Within the North American Numbering Plan, the 305 area code is known as a central office code, which is the code that is used for a numbering plan area (NPA). All phone numbers have a three-digit area code that can identify a certain geographic area, or in some cases a specific carrier. In Florida, the 305 area code is used to identify Miami-Dade County, as well as its surrounding areas. All phone numbers in this area code are prefixed with the digits “305” when dialed in the United States or Canada. All existing 305 numbers, as well as newly created 555-prefix-four-digit numbers, are assigned in this area code.
