California Area Codes Overview

California, the most populous state in the United States, is served by a diverse range of area codes, reflecting its vast geographical expanse and densely populated urban centers. Major metropolitan areas like Los Angeles (213, 310, 323, 424, 626), San Francisco (415, 628), and San Diego (619, 858) are characterized by multiple area codes due to their size and population. The Silicon Valley region, a global tech hub, has area codes such as 408 and 669. Northern California, including Sacramento (916), and Central California (559, 661) contribute to the mosaic of area codes across the state. California's area codes not only provide a means of telecommunications but also serve as markers of the state's diverse communities, industries, and cultural landscapes.
