California Area codes are numerical codes that are used to identify a specific geographical region within a country or a state. California is the most populous state in the United States, and it is divided into multiple area codes to facilitate the communication process for its residents. In this article, we will explore the different area codes in California and provide you with the information you need to make informed decisions.
What are area codes?
Area codes are three-digit numbers that are used to identify a specific geographical region within a country or a state. The purpose of these codes is to simplify the communication process by providing a unique identifier for each location. In California, area codes are assigned based on population density and geographic location.
How are California area codes assigned?
The California Public Utilities Commission (CPUC) is responsible for assigning area codes in the state. When a new area code is needed, the CPUC will conduct a study to determine the best way to divide the existing area code. The factors that are considered during this process include population density, existing area codes, and geographic location.
