California area code questions

Which area code should I choose in California?
Start with the first three digits after +1 on the number you want to check. The codes in this directory are associated with places including Stockton, Los Angeles, Folsom, Inglewood, Montebello, Hayward, Modesto, Fresno, Santa Rosa, San Jose, San Francisco, Escondido, Oakland, Chico, Long Beach, San Diego, Pasadena, San Rafael, Palo Alto, Anaheim, Bakersfield, Sunnyvale, Glendale, Palm Springs, Santa Barbara, Burbank, Oxnard, Monterey, Pomona, La Jolla, San Bernardino, Sacramento, Concord, Irvine, and Riverside. The listed places are examples, not a complete map of each code’s boundaries.
Which California area codes share coverage?
NANPA groups these codes in shared numbering complexes: 209 / 350; 213 / 323 / 738; 279 / 916; 310 / 424; 341 / 510; 357 / 559; 369 / 707; 408 / 669; 415 / 628; 442 / 760; 530 / 837; 619 / 858; 657 / 714; 747 / 818; 805 / 820; 840 / 909. Members can serve overlapping areas; being in the same complex does not necessarily mean identical geographic boundaries.
How do I dial a number in California?
Open the individual area code to check its local dialing rule. For a phone lookup, enter +1 followed by the three-digit area code and the seven-digit number. A state or area code alone is not enough to look up a particular number.
Does an area code from California show where the caller is?
No. An area code describes a number’s assigned region. People can keep numbers after moving, use them while traveling, or place internet-based calls. Caller ID can also be spoofed, so the code does not confirm the caller’s location or identity.
