How Miami came to have 3 area codes

The original Miami area code is 305, in service since 1947. As the area ran low on available numbers, overlay codes were added over the same region for new phone lines: 786 (1998) and 645 (2023). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Miami now uses all 3 codes and every local call is dialed with ten digits.
