323 Area Code: Central Los Angeles Location and Time Zone

Introduction

The 323 area code belongs to central Los Angeles: it was drawn in 1998 as a ring of city neighborhoods and nearby Los Angeles County cities wrapped around downtown's 213. Since 2017 the two codes have shared one map, and a third code, 738, joined them in November 2024, so a 323 number today is one of three possible codes for the same place.

Whether an unknown 323 phone number rang your phone or you need one for a business, this guide covers the code's reach, its merged boundary with 213, dialing and call safety, drawing on California Public Utilities Commission (CPUC) decisions and notices.

Where Is the 323 Area Code?

Area code 323 is in Los Angeles County, California. In its July 2016 decision on the code, the CPUC described the 323 area as surrounding the region covered by 213, made up largely of the City of Los Angeles plus neighboring cities and unincorporated parts of the county. The commission compared the layout to a donut, with 213 as the hole in the middle.

So the honest answer to "323 area code is where" is the central part of Los Angeles outside the downtown core, not the entire metro area. The San Fernando Valley (818) and Long Beach (562), for example, have codes of their own. For downtown itself and the older history of the city's numbering, read the 213 area code guide.

By 2016, downtown's 213 had shrunk to three rate centers, the local serving areas that numbers are tied to, while 323 had 12, and the City of Los Angeles reached into 11 of them.

Cities and Counties in the 323 Area Code

Every part of the 323 area lies in Los Angeles County. Because 213 and 323 have covered identical ground since 2017, the CPUC now describes their cities together rather than code by code:

The list covers the combined region, so it can't say whether a given Inglewood line was 213 or 323 before 2017. Some cities also touch other codes: CPUC reports place parts of Commerce, Montebello and South Gate in 562, and Glendale and Pasadena rate centers in 818.

A code map for the whole state, including the neighbors mentioned above, is on the California area codes page.

323 Area Code Time Zone (Pacific Time)

Every number in the 323 region keeps Pacific Time. Federal regulations put the part of the continental US west of the Mountain boundary line, California included, in the Pacific zone, and under federal law its standard time runs eight hours behind Coordinated Universal Time.

Los Angeles follows the federal daylight saving schedule: clocks move to Pacific Daylight Time (UTC-7) at 2 a.m. on the second Sunday in March and back to Pacific Standard Time (UTC-8) at 2 a.m. on the first Sunday in November. New York shifts on the same dates, so central Los Angeles stays three hours behind the East Coast all year.

323, 213 and 738: Three Area Codes, One Region

The 1998 split lasted less than two decades. In February 2015, the North American Numbering Plan Administrator (NANPA) estimated that 323 would run out of assignable numbers in the first quarter of 2018. Instead of adding a brand-new code, the CPUC chose a boundary elimination overlay in Decision 16-07-014, adopted July 14, 2016: the line between 213 and 323 would be erased so either code could be assigned anywhere in the combined area.

• January 2017: permissive dialing began, so callers could start using 1 + area code + number.
• July 8, 2017: that pattern became mandatory for all calls from 213 and 323 numbers; calls dialed the old way reached a recording.
• August 1, 2017: new lines in the former 323 region could receive 213 numbers, and new lines in old 213 territory could receive 323.
• September 19, 2022: only 123 prefixes, about 7.7%, remained in 213/323.
• March 16, 2023: the CPUC approved 738 as an additional overlay.
• November 1, 2024: customers requesting new service could start receiving 738 numbers.

No one had to change numbers, and the CPUC says call prices and local calling areas stayed the same. A 213, 323 or 738 number now means central Los Angeles, not a particular side of the old boundary. The CPUC keeps its notices on the 213/323/738 area codes page.

Is 323 a Country Code? What That Search Really Means

No. 323 is an area code in the North American Numbering Plan, where the United States uses country code 1. The international form of a 323 number is +1 323 followed by seven digits, for example +1 323 555 0147.

Searches such as "323 area code Texas" or "323 area code Florida" usually come from seeing the digits without context. Area code 323 serves only Los Angeles County, California, although a mobile or internet phone number can be used from anywhere.

323 Area Code vs ZIP Codes

A 323 area code doesn't correspond to a ZIP code, so a search for the "zip code for area code 323" has no single answer. Area codes come from the telephone numbering plan; ZIP codes are U.S. Postal Service delivery codes. The 323 region spans many ZIP codes across Los Angeles and its neighboring cities, and neither map follows the other's lines.

How to Tell If a Call From 323 Is Legitimate (Spam Calls)

Most calls from 323 numbers come from people and businesses in Los Angeles. The weak spot is caller ID: the FTC warns that scammers fake numbers, including "neighbor spoofing" that copies your own area code so a call looks local. That makes area code 323 spam a question of what the caller wants, not the digits. Slow down if the caller:

• is a stranger who says the matter can't wait;
• claims to be a government office, bank or utility and threatens penalties or a shutoff;
• wants you to pay right away or read out card or bank details;
• asks for a one-time passcode that was just sent to your phone;
• is a recording that tells you to press a key.

Hang up and call the organization back on a number from its website or your statement, never the one that called you. During a robocall, don't press any numbers; the FTC says that can lead to more robocalls. Repeat callers can be blocked in your phone's settings, with a call-blocking app or through your carrier's blocking and labeling service.

How to Dial a 323 Phone Number

Since July 8, 2017, callers in the 213/323 region must dial 1, the area code and the seven-digit number for every call, even to a neighbor with the same code. Numbers in 738 follow the same rule.

According to the CPUC, 911, 988 and the 211 through 811 service numbers still take three digits. Businesses should reprogram equipment that dials on its own; the CPUC's 2017 reminder named alarm systems, fax machines, gates, speed dialers and call forwarding settings.

How to Get a 323 Phone Number for Your Business

A central Los Angeles number helps when your customers are in the city or nearby places such as Huntington Park or West Hollywood. New lines in this region can be assigned 213, 323 or 738, so decide early whether you want 323 specifically or simply a local number for the area.

1. 1Check availability. Start from the US area codes list and check which 323 numbers are available; a 213 or 738 number covers the same region if choices are thin.
2. 2Route the calls. Ring your team's phones and computers through the apps, or add anauto attendant in front so callers pick sales, support or billing.
3. 3Add texting. Turn on business texting so customers can message the number printed on your site.
4. 4Port instead of replacing. Already have a 323 line with another carrier? Port the number so existing customers keep reaching you.

A Ringflow free trial lets you test the whole setup before you publish the number.

Conclusion

The 323 area code is central Los Angeles outside downtown's core: the ring of city neighborhoods and adjoining Los Angeles County cities that split from 213 in June 1998. 213 has covered the same map since 2017 and 738 since November 2024, so the code identifies the region but not the neighborhood.

Dial 1 plus ten digits for every call there, judge unfamiliar callers by what they ask for rather than the number on the screen, and report scams to the FTC. If you want a local presence for customers in the area, check 323 availability and start a free trial with Ringflow.
