About the 831 area code
Since 1998, area code 831 has covered Monterey, Salinas, and Santa Cruz in California. Everyone in the territory keeps Pacific Time (GMT -8).
The code was born in a split that year, when its ground was cut away from area code 408. It has operated by itself from the start, with a single code handling the territory and no overlay in place.
Dialing note: 831 was carved out of the 408 territory and went into service in 1998.
Numbering details on this page (service dates and overlay status) are checked against the NANPA numbering registry. Registry data as of 07/16/2026.
