323 Area Code: Hollywood, Boyle Heights, and Southeast LA Guide

Introduction

The 323 area code answers across the heart of Los Angeles. It covers Hollywood's working studios and the Walk of Fame, the Chicano cultural landmarks of Boyle Heights and East LA, the jazz clubs of Leimert Park, and the industrial cities of southeast LA County along the river.

This guide maps where the 323 area code reaches and the entertainment, cultural, and manufacturing economy that defines it. It covers the region's Pacific Time calling window and its 1998 origin as an overlay to the original 213 area code. And it shows how to put a Los Angeles number in front of customers in minutes.

Where the 323 Area Code Reaches

The 323 area code covers central Los Angeles neighborhoods and a cluster of independent cities in southeast Los Angeles County. It shares its entire territory with the 213 and 738 area codes rather than covering separate ground.

• Hollywood — the entertainment industry's historic production and tourism center
• Silver Lake, Echo Park, and Los Feliz — hillside neighborhoods known for music, arts, and independent culture
• Boyle Heights and East Los Angeles — the historic center of LA's Mexican-American and Chicano community
• Leimert Park — the historic hub of LA's Black arts and jazz scene
• West Hollywood and Hancock Park — an entertainment-adjacent city and a historic residential district
• Bell, Huntington Park, South Gate, Maywood, and Cudahy — dense, industrial southeast LA County cities along the Los Angeles River

The footprint pairs Hollywood's entertainment production with historic cultural neighborhoods and a working-class industrial corridor. So a 323 area code line can signal a Hollywood production company, a Boyle Heights community organization, or a Southeast LA manufacturer. One prefix carries some of the most varied identities in Los Angeles.

Hollywood: Studios, the Walk of Fame, and Entertainment Production

Hollywood itself sits inside the 323 area code, and it remains a working production center as much as a tourist destination.

Paramount Pictures and Working Studios

Paramount Pictures has operated its studio lot on Melrose Avenue in Hollywood since 1926. It's one of the last major studios still physically located in the neighborhood that gave the industry its name. Sunset Gower Studios and a dense network of post-production, casting, and production-service companies keep Hollywood a working production hub, not just a historic backdrop.

Hollywood Walk of Fame and Tourism

The Hollywood Walk of Fame has embedded stars honoring entertainment figures along Hollywood Boulevard since 1960. The boulevard, the TCL Chinese Theatre, and the Capitol Records Tower draw millions of tourists a year. That gives the 323 area code a hospitality and retail economy layered on top of its production base.

Boyle Heights, Leimert Park, and Southeast LA's Cultural and Industrial Corridor

Beyond Hollywood, the 323 area code carries some of Los Angeles's most historically significant cultural neighborhoods alongside a dense industrial corridor to the southeast.

Boyle Heights and East Los Angeles

Boyle Heights and East Los Angeles have anchored LA's Mexican-American community for generations. The area is home to Mariachi Plaza, a dense concentration of Latino-owned businesses, and a long civil-rights and labor-organizing history that still shapes the neighborhood's civic identity.

Self Help Graphics & Art, founded in Boyle Heights in 1970, has anchored the neighborhood's Chicano arts movement for more than five decades. It runs one of the country's most influential printmaking studios and hosts one of LA's largest Day of the Dead celebrations every year.

Leimert Park

Leimert Park has served as the cultural center of Black Los Angeles since the mid-20th century. It's home to jazz clubs, art galleries, and independent bookstores that have made the neighborhood a hub for Black art and music in the city.

The World Stage is a jazz performance and education space founded in Leimert Park in 1989 by drummer Billy Higgins and poet Kamau Daáood. It still runs workshops and live shows that keep the neighborhood's jazz tradition active rather than purely historical.

Dodger Stadium and Elysian Park

Dodger Stadium sits in Elysian Park near Echo Park, and the Los Angeles Dodgers have played there since 1962. The stadium draws millions of fans a year to one of the most storied franchises in baseball. That gives the 323 footprint a major sports-tourism anchor.

Southeast LA County's Manufacturing Cities

Southeast of downtown, Bell, Huntington Park, South Gate, Maywood, and Cudahy form a dense corridor of small, heavily Latino immigrant cities built on manufacturing and warehousing along the Los Angeles River. That gives the 323 footprint a working-class industrial identity distinct from Hollywood's production economy.

For a business working the wider Los Angeles market, the 323 area code sits directly against the San Fernando Valley's 818 area code across the Hollywood Hills.

Time Zone and Calling Hours for the 323 Area Code

The entire 323 area code observes Pacific Time — UTC-8 (PST) in winter and UTC-7 (PDT) during Daylight Saving. Central Los Angeles shares the clock with the rest of California and the West Coast.

East Coast teams calling area code 323 are three hours ahead. Early-afternoon Eastern outreach lands mid-morning in Los Angeles, so plan around the three-hour gap to catch the full Central LA business day.

323 History

The 213 area code covered all of Los Angeles from 1947 until a series of geographic splits narrowed it down to downtown and central Los Angeles by the 1990s. Those splits included the 1991 split that created 310.

Rather than split 213 again, regulators added the 323 area code as an overlay on June 13, 1998. It covers the exact same central LA territory rather than dividing it into new ground. That decision avoided forcing existing 213 customers to change their numbers.

That overlay approach reflected a broader shift in how regulators handled number exhaustion in dense urban markets through the 1990s. Rather than repeatedly redrawing geographic boundaries and forcing residents to change numbers, overlays let a shared territory simply carry more than one area code at once.

In 2017, the California Public Utilities Commission eliminated the boundary between 213 and 323 entirely. That merged them into a single combined overlay complex where new numbers could be assigned from either code anywhere in the territory. A third overlay, 738, joined the same complex on November 1, 2024.

How to Get a 323 Area Code Number

1. 1Cloud phone platform — search available 323 numbers in real time and activate a line the same day, with no hardware and no technician visit.
2. 2Port your existing number — already run a 323 line on another carrier? Move it over without downtime and keep the number active through the transition.
3. 3Wireless SIM or landline carrier — valid for a single physical handset, but slower to provision and harder to scale seat by seat.

With letsdial, a UCaaS (Unified Communications as a Service) platform built for exactly this, a 323 number provisions in under three minutes on a free trial, no credit card required, so a Los Angeles presence can be answering calls the same afternoon.

Call Trust in Central LA

The 323 area code market runs on entertainment-production relationships, community-organization referrals in Boyle Heights and Leimert Park, and manufacturing-supplier networks in southeast LA County — settings where an unknown out-of-state number gets screened before it's answered. A recognizable local prefix earns the first hearing, and in a market fielding constant cold outreach, that first impression often decides whether the conversation happens.

STIR/SHAKEN for Production, Community, and Manufacturing Contacts

Apply STIR/SHAKEN attestation so every outbound 323 call arrives verified with your registered business name on screen. As a UCaaS provider, letsdial registers text campaigns for 10DLC compliance from day one and warms new numbers before scaling volume. That means a verified line reads as central-LA-local rather than out-of-area.

A trusted 323 line is the difference between a Hollywood production contact or a Southeast LA manufacturing buyer picking up the call and routing it straight to voicemail.

Conclusion

The 323 area code covers some of the most culturally significant square miles in Los Angeles — Hollywood's working studios and Walk of Fame, Boyle Heights and East LA's Chicano heritage, Leimert Park's Black arts scene, and the industrial cities of southeast LA County. From Paramount's Melrose Avenue lot to Dodger Stadium, it identifies a business as genuinely central LA.

Standing up a line takes minutes on a cloud UCaaS platform, with STIR/SHAKEN attestation so calls arrive verified rather than flagged. Put a 323 number in front of production contacts, community partners, and manufacturing buyers, and let a familiar prefix open the door first, with letsdial handling the setup end to end.
