About California Area Codes

California (CA) uses 36 telephone area codes to serve its residents and businesses. With an estimated population of 59,652,083, California is one of the most heavily coded states in the North American Numbering Plan (NANP). The state is primarily in the Pacific Time Zone (PDT). The current local time in California is 9:50 PM.

The largest cities in California include Los Angeles (pop. 12,750,807), San Francisco (pop. 3,592,294), San Diego (pop. 3,220,118), Riverside (pop. 2,107,852) and Sacramento (pop. 1,898,019) . California has 58 counties spread across its territory. Each area code in CA covers a geographic region of the state, with some areas using overlay codes that share the same geographic territory as an existing area code.

When calling a California phone number from outside the area code, you must dial the full 10-digit number: the 3-digit area code followed by the 7-digit local number. Many parts of California now require 10-digit dialing even for local calls due to overlay area codes and the nationwide 988 Suicide & Crisis Lifeline implementation.
