California, the most populous state in the United States, has a complex system of area codes reflecting its vast geography and diverse population. As of 2023, California utilizes over 20 area codes, the first of which, 213, was established in 1947, serving the Los Angeles region. These codes have been introduced in response to the state's growing population and increased demand for telephone services, leading to the implementation of new area codes such as 310, 415, and 818 over the ensuing decades.
California's area codes cover a wide array of urban and rural regions, including major metropolitan hubs like San Francisco, San Diego, and Sacramento. The area codes also reflect significant cultural and economic zones, with specific codes often associated with particular industries, such as Silicon Valley's high-tech sector, which spans several area codes, including 408 and 650.
Moreover, California's area codes have played a vital role in the development of telecommunications infrastructure. The state's expansive coverage is crucial for facilitating communication across various sectors, including entertainment, technology, and agriculture, further accentuated by the rise of mobile technology which necessitates more numbers.
Notably, California also employs overlays—where multiple area codes serve the same geographic region—to accommodate the proliferation of devices requiring separate phone numbers, showcasing the state’s adaptability to ongoing technological advancements and demographic shifts. Understanding California’s area codes provides insight into the state’s unique communication landscape influenced by its size, diversity, and economic dynamism.

California has 32 area codes (747, 818, 510, 626, 949, 657, 714, 925, 442, 760, 916, 805, 209, 661, 951, 323, 562, 650, 707, 310, 424, 408, 669, 530, 909, 619, 559, 831, 213, 415, 628, 858). These area codes are split between cities or states, so if you want to call to California, you need to know exactly where you would like to call.
The first 3 digits to call California may vary depending on where you want to call to, being one or the other depending on the region or city. Take a look at our listing above to find out which area code you need.
Calling California from another state in the United States is considered a long-distance call. Here’s how to make the call: First, dial the area code for California. Each state, and sometimes specific cities within a state, has unique area codes. Then, enter the 7-digit phone number of the person or business you’re trying to reach. If you’re calling from a landline, check with your provider, as long-distance charges may apply. However, most mobile carriers in the U.S. offer nationwide calling without additional fees. Alternatively, you can use VoIP or internet-based calling apps, like Skype, Zoom, or WhatsApp, to bypass traditional long-distance charges. The number you want to reach should look like this: 1-(AreaCode)-111-2222.
When making calls within the United States, dialing +1 depends on several factors. On most modern mobile phones, carriers automatically recognize the country code when calling within the U.S., so dialing +1 is usually not required; you can simply enter the area code followed by the phone number, such as 213-555-1234. If you’re using a landline, dialing 1 (the U.S. country code) before the area code and phone number is often necessary for long-distance calls; for example, calling from one state to another may require dialing 1-213-555-1234. When calling the U.S. from another country, dialing +1 is necessary, so a call from abroad would be formatted as +1-213-555-1234. VoIP and internet-based calling platforms, like Skype and WhatsApp, generally handle country codes automatically, making it unnecessary to dial +1 manually for U.S. numbers.
