Miami, FL utilizes an area code overlay in which area codes 305 and 786 serve the same geographic area. The area code overlay which is in use was established in 1998 at which time area code 786 was created as a partial overlay of 305 and then in 2008 was extended as a complete overlay of area code 305. Ten digit dialing (area code + seven digit number) is necessary because two different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
In addition to Miami, FL area codes 305 and 786 serve Miami-Dade County and the Florida Keys portion of Monroe County, including the larger cities and communities of Carol City, Coral Gables, Coral Terrace, Country Club, Cutler Ridge, Doral, Golden Glades, Hialeah, Homestead, Kendale Lakes, Kendall, Leisure City, Miami, Miami Beach, Miami Lakes, Miramar, Norland, North Miami Beach, Richmond and Westchester in addition to many smaller communities.
