How Palm Bay came to have 2 area codes
The original Palm Bay area code is 321, in service since 1999. As the area ran low on available numbers, an overlay code was added over the same region for new phone lines: 689 (2019). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Palm Bay now uses all 2 codes and every local call is dialed with ten digits.
