What is Area Code 323?
The 323 area code is a telephone code registered in the North American Numbering Plan (NANP) and launched in June 1998. The North American Numbering Plan Administrator introduced 323 as an overlay to the previous area code, 213, serving central Los Angeles County.
Where is 323 Area Code Located?
The area code 323 is located in Los Angeles, California. It serves 29 cities. Some major areas are Long Beach, Glendale, Cudahy, Beverly Hills, and Maywood Westmont. It also roughly covers the downtown area of Los Angeles. Bell and Huntington Park are popular cities in southeast Los Angeles County. The only county served by 323 is Los Angeles County.
History of Area Code 323
323 phone code was implemented on June 13, 1998, and it was one of 21 area codes introduced that year. It was the 240th local code in service. As for the state of California, it was the 21st area code. Today, California has 38 telephone codes. These additions of new area codes over time reflect the continuously growing demand for phone numbers.
The phone numbers in the 213 prefix were running out. 323 was launched to relieve the pressure on the existing 213 area code. After the introduction of 323, 213 was left to serve only downtown Los Angeles. In 2017, 213 and 323 were combined as an overlay to serve the same areas of Los Angeles.
The North American Numbering Plan Administration (NANPA) has predicted that the 323 phone numbers may run out soon. As a relief plan, the California Public Utilities Commission proposed a 738 area code as a possible overlay for dialing code 323. This possible new overlay will launch its service on November 1, 2024.
