Area codes serving Los Angeles
Los Angeles sits in California, part of the West region and the Pacific Time zone. The Los Angeles area uses 7 area codes (213, 310, 323, 424, 738, 747, 818). They cover different parts of the metro — see the table below for which code serves where — and codes that share a territory are overlays of each other.
The original code is 213 (in service since 1947). 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 Los Angeles, 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 213), ask the carrier whether any blocks remain, or request a number transfer. All codes here dial identically and cost the same.
Dialing in Los Angeles
Wherever two codes overlay the same ground, 10-digit dialing is mandatory. Dialing the full 10-digit number always works, so it is the safest habit across the whole metro. See 10-digit dialing and overlay area codes for the background. For every code in California, visit the California area codes page.
