California Phone Numbers and Area Codes

In California, the system of telephone numbering is managed under the North American Numbering Plan (NANP), which is also used in the United States, Canada, and some Caribbean countries. While the Federal Communications Commission (FCC) has exclusive jurisdiction over telephone numbering in the United States, it has delegated specific authority to state regulatory agencies. In California, this authority is granted to the California Public Utilities Commission (CPUC), which conducts area code relief and enforces number conservation in accordance with Public Utilities Code Section 7930-7943. Currently, California has 39 area codes, the most area codes of any state. A new area code is added to a geographic area when there are no more three-digit prefixes available in the existing area code. Since 2006, California has added fourteen area codes using the overlay method.

California is witnessing a surge in demand for telephone numbers and area codes due to factors such as competition for local phone service, the popularity of various communication devices and services, and the state's growing population and economy. However, the current number allocation system, which dates back to the 1940s, is inefficient in meeting this demand. Until 1997, one phone company provided local telephone service in a particular area, and new area codes were introduced as the population grew. But the Telecommunications Act of 1996 opened up competition, leading to multiple companies entering the market, each requiring its own set of numbers.

Previously, telecom companies were assigned blocks of 10,000 numbers, or prefixes, regardless of their actual need, leading to an artificial demand for more numbers and the creation of more area codes. This system, efficient when one company served all customers in an area, is no longer viable with over 200 telecom companies in California. The inefficient allocation system, coupled with the rising demand for numbers, has led to a rapid increase in area codes in the state. Without significant number conservation measures, the industry planned to add 22 more area codes in California by 2003, highlighting the need for more efficient solutions than just adding new area codes.
