Area codes serving Sacramento
Sacramento sits in California, part of the West region and the Pacific Time zone. Its numbers are spread across an overlay of 2 codes that all cover the same ground: 279, 916.
The original code is 916. As the area ran low on numbers, regulators added overlay codes on top instead of splitting the city, so longtime residents kept their numbers while new lines received a newer code.
How to pick an area code for a new number
When you activate a new line in Sacramento, the carrier assigns whichever code has numbers available — you usually can't choose. If a specific code matters to you (for example the prestige of 916), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.
Dialing in Sacramento
Because Sacramento is an overlay area, 10-digit dialing is mandatory: always dial the area code plus the seven-digit number, even for a neighbor. See 10-digit dialing and overlay area codes for the background. For every code in California, visit the California area codes page.
