323 Area Code: Los Angeles, California

The 323 code wraps around downtown Los Angeles, covering the older inner neighborhoods that surround the original 213 footprint — Hollywood, East Hollywood, Koreatown's eastern blocks, parts of South Los Angeles, and a long arc of communities running through Echo Park, Silver Lake, and Boyle Heights. The code was carved out of 213 when the inner-city region's number demand made an additional code necessary, and it has since taken on the working role of identifying numbers tied to the city's older residential and commercial neighborhoods.

Cities including Anaheim, Bakersfield, Chico, and Concord recur in the directory's records linked to 323 numbers, alongside many other California place names. None of those sit inside the 323 footprint; their appearance is driven by the unusually high level of inter-city mobility California exhibits in public records and by routine porting, prior registration, and address overlaps. We hold detailed records on 704 distinct prefixes within 323, a substantial set that nevertheless represents our working subset rather than the full population of prefixes assigned to the code.

The Los Angeles housing market continues to reshape the city's demographic profile, and 323's neighborhoods carry valuations far above national norms — typical home values run several times the US median. Household income lands above the country-wide figure but well below what coastal Westside zip codes would show on their own. The city's population places it among the largest in the country, and median age skews a touch younger than the national reading.
