In this article, we’ll take a closer look at the history, geography, culture, economy, and telecommunications infrastructure of the 657 area code. Whether you’re a resident, business owner, or visitor, we hope you find this information helpful and informative.

History of the 657 Area Code:

The 657 area code was introduced on September 23, 2008, as an overlay to the existing 714 area code. The decision to introduce a new area code was made by the California Public Utilities Commission in response to a growing demand for phone numbers in the region. The 714 area code had been in use since 1951 and was running out of available phone numbers due to the proliferation of cell phones, pagers, and other telecommunications devices.

The introduction of the 657 area code meant that new phone numbers in the region would be assigned the 657 code instead of the 714 code. However, existing phone numbers with the 714 code would not be affected and would continue to work as usual. The overlay method was chosen instead of a geographic split, which would have required some residents and businesses to change their phone numbers and incur additional costs.

Since its introduction, the 657 area code has not undergone any major changes or updates. However, as with any area code, there have been occasional reports of scams or fraud attempts using the 657 code. Residents and business owners in the area are advised to be vigilant and to report any suspicious activity to the authorities.
