The 213/323 area code region was formed in 2017 when the 323 area code underwent an overlay that eliminated the boundary between the 213 area code region and the neighboring 323 area code region. The resulting combined 213/323 region is thus served by both the 213 and the 323 area codes.
On August 22, 2022, the North American Numbering Plan Administrator (NANPA) filed Application (A.) 22-08-009 on behalf of the telecommunications industry, requesting that the CPUC approve an overlay area code in the 213/323 area code region to provide additional numbering resources in the region.
On March 16, 2023, the CPUC approved a new area code of 738 as an overlay on top of the 213/323 area code. Read the press release here.

Background
The 213 area code was created in 1947 and was one of the original three area codes in California. The 213 area code was split five times between 1951 and 1991, creating the 714 area code in 1951, the 805 area code in 1957, the 818 area code in 1984, the 310 area code in 1991 and the 323 area code in 1998. In 2017, the CPUC approved an elimination of the boundary between the 213 and 323 area codes, creating the 213/323 overlay area codes. The 213/323 area codes generally serve the downtown portion of the City of Los Angeles and the surrounding cities and communities, including Alhambra, Bell, Bell Gardens, Beverly Hills, Commerce, Cudahy, Glendale, Hawthorne, Huntington Park, Inglewood, Lynwood, Maywood, Montebello, Monterey Park, Pasadena, Rosemead, South Gate, South Pasadena, Vernon and West Hollywood, as well as unincorporated portions of Los Angeles County.

I'm an expert in telecommunications and area code management, with a deep understanding of the North American Numbering Plan (NANP) and its administration. My knowledge extends to the intricate details of area code overlays, boundary eliminations, and the regulatory processes involved. Let me shed light on the concepts mentioned in the article you provided.
The 213/323 area code region underwent a significant transformation in 2017 when the 323 area code experienced an overlay, effectively removing the boundary between the 213 and 323 area codes. This move resulted in a combined 213/323 region served by both area codes.
On August 22, 2022, the North American Numbering Plan Administrator (NANPA) initiated Application (A.) 22-08-009 on behalf of the telecommunications industry. The purpose was to request approval from the California Public Utilities Commission (CPUC) for an overlay area code within the 213/323 region to address the need for additional numbering resources.
Subsequently, on March 16, 2023, the CPUC approved the introduction of a new area code, 738, as an overlay on top of the existing 213/323 area code. This decision aimed to provide the necessary numbering resources to meet the demands of the region.
The background information provides a historical context, indicating that the 213 area code was established in 1947 and was among the original three area codes in California. Over the years, the 213 area code underwent multiple splits, leading to the creation of new area codes, including 323 in 1998.
In 2017, the CPUC approved the elimination of the boundary between the 213 and 323 area codes, resulting in the formation of the 213/323 overlay area codes. These area codes primarily serve the downtown portion of the City of Los Angeles and surrounding cities and communities.
