Area code 323 serves central Los Angeles and surrounding neighborhoods, including Hollywood, East LA, Koreatown, and Echo Park. It was introduced in 1998 as a split from the original 213 area code, which once covered all of Southern California. In 2017, area codes 213 and 323 were overlaid, and now both codes serve the same inner-city LA region. Known for its cultural landmarks, creative industries, and diverse communities, 323 is deeply embedded in the identity of Los Angeles. It’s frequently referenced in entertainment, music, and streetwear culture. With ten-digit dialing required, 323 has remained popular among residents and businesses seeking a local LA vibe. The area is a hub for media, arts, and nightlife, reflecting the vibrancy of the city’s urban core.
