323 Area Code: Los Angeles, CA | Location & Time Zone

The 323 area code is one of the most recognizable telephone area codes in Southern California, serving the heart of Los Angeles and its surrounding communities. Established in 1998, the 323 area code covers central Los Angeles, including iconic neighborhoods like Hollywood, East Los Angeles, and Downtown LA. As part of the North American Numbering Plan (NANP), this area code plays a vital role in connecting millions of residents and businesses across one of the nation’s most populous metropolitan areas.

What is the 323 Area Code?

The 323 area code is a geographic telephone area code serving central Los Angeles, California. It was introduced on June 13, 1998, as a split from the original 213 area code, which had served the entire Los Angeles basin since 1947. The split was necessary due to the rapid population growth and the increasing demand for telephone numbers in the Los Angeles metropolitan area. Today, the 323 area code serves approximately 1.8 million residents across central and eastern portions of the City of Los Angeles, making it one of the most densely populated area code regions in the United States.

The 323 area code is exclusively used for landline and mobile phone numbers within its designated geographic boundaries. It operates alongside the 213 area code, which was retained for downtown Los Angeles and the central business district. Both area codes now function as overlays in some portions of their coverage areas, requiring ten-digit dialing for all calls.

History of 323 Area Code

When Was 323 Created?

The 323 area code was officially activated on June 13, 1998, following a split from the historic 213 area code. The 213 area code had been in service since 1947 as one of California’s original area codes, covering the entire Los Angeles metropolitan area. By the 1990s, explosive population growth, the proliferation of cell phones, pagers, and fax machines had exhausted the available phone numbers within the 213 area code.

The California Public Utilities Commission and telecommunications industry planners determined that a geographic split was necessary. The solution was to retain 213 for the downtown Los Angeles core and central business district, while assigning 323 to surrounding neighborhoods and communities. This split provided millions of new telephone numbers to meet demand while preserving the prestigious 213 code for the historic downtown area.

Area Code Changes and Overlays

When the 323 area code was introduced in 1998, existing 213 customers in the areas that became 323 territory were required to change their phone numbers. This affected millions of residents and thousands of businesses, making it one of the largest area code transitions in U.S. history. To ease the transition, a permissive dialing period allowed both old 213 and new 323 numbers to work temporarily before the full cutover.

The 323 and 213 area codes now share some geographic territory in central Los Angeles, functioning as a de facto overlay in certain zones. This requires ten-digit dialing (area code + seven-digit number) for all calls within the region, even for local calls. Despite the complexity, this system has successfully maintained an adequate supply of telephone numbers for one of America’s largest and fastest-growing urban centers.

How to Call 323 Area Code

Dialing Within the Area Code

If you are calling from one 323 number to another 323 number within the same geographic area, you must use ten-digit dialing. The format is: 323-XXX-XXXX. The “1” prefix is not required for local calls within the same area code or to the overlapping 213 area code. However, some phone systems and carriers may require the “1” prefix, so if your call doesn’t connect, try dialing 1-323-XXX-XXXX.

Dialing From Other Area Codes

When calling a 323 area code number from anywhere else in the United States, Canada, or other North American Numbering Plan countries, you must dial: 1-323-XXX-XXXX. The “1” is the country code for the United States and Canada within the NANP system. Long-distance charges may apply depending on your phone plan, though many modern mobile and landline plans include unlimited nationwide calling.

International Dialing

To call a 323 area code number from outside the United States, dial your country’s international access code (often “00” or “+”), followed by the U.S. country code “1”, then the area code and phone number: +1-323-XXX-XXXX. For example, from the United Kingdom, you would dial 00-1-323-XXX-XXXX. From a mobile phone, you can typically use the “+” symbol instead of your country’s access code. International calling rates will apply based on your telephone service provider.
