About California phone numbers
California phone numbers are 10-digit North American Numbering Plan numbers under country code +1. The first three digits are the area code, listed above. Newer overlay codes cover the same geography as an existing code once its 10,000-line prefixes have been assigned - which is why the largest metro areas in California may have several codes covering the same neighborhoods.
If you're getting calls from an unfamiliar CA number, use the reverse-phone lookup at the top of this page. Scam callers frequently spoof local CA codes to appear trustworthy - the lookup shows carrier, location, and any recent scam reports on that specific number.
