Why Does California Have So Many Area Codes?

California's large population and the proliferation of cell phones and other communication devices have necessitated the introduction of new area codes over the years. As the demand for phone numbers increases, new area codes are added to ensure that everyone has access to a unique phone number.

How Area Code Overlays Work

In many regions, new area codes are introduced as overlays. This means that the new area code is added to the same geographic area as an existing area code. In these cases, ten-digit dialing (area code + phone number) becomes mandatory to ensure that calls are routed correctly. — New Jersey State Of Emergency: What You Need To Know
