How Hesperia came to have 2 area codes
The original Hesperia area code is 760, in service since 1997. As the area ran low on available numbers, an overlay code was added over the same region for new phone lines: 442 (2009). Existing numbers kept their original code — an overlay never forces anyone to change their number — which is why Hesperia now uses all 2 codes and every local call is dialed with ten digits.
