How Brea came to have 2 area codes
The original Brea area code is 714, in service since 1951. As the area ran low on available numbers, an overlay code was added over the same region for new phone lines: 657 (2008). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Brea now uses all 2 codes and every local call is dialed with ten digits.
