How to stop spam calls in California

California has 34 area codes. Spam callers spoof them so the call looks local. Blocking numbers one at a time never ends, because they rotate daily.

Your number gets on their lists from people-search sites that publish it next to your name and address. Get it off those sites and you drop off the lists built from them.

Area codes: 209 Stockton · 213 Los Angeles · 279 Sacramento · 310 Los Angeles · 323 Los Angeles · 408 San Jose · 415 San Francisco · 424 Los Angeles · 442 Oceanside · 510 Oakland · 530 Redding · 559 Fresno · 562 Long Beach · 619 San Diego · 626 Pasadena · 628 San Francisco · 650 San Mateo · 657 Anaheim · 661 Bakersfield · 669 San Jose · 707 Santa Rosa · 714 Anaheim · 747 Los Angeles · 760 Oceanside · 805 Oxnard · 818 Los Angeles · 820 Oxnard · 831 Salinas · 858 San Diego · 909 San Bernardino · 916 Sacramento · 925 Concord · 949 Irvine · 951 Riverside
