About Area Code 323
Area code 323 is a North American Numbering Plan (NANP) area code that has been in service since 1998. It is administered by NANPA on behalf of the FCC and serves the California region anchored on Los Angeles.
323 now shares its territory with an overlay code (213). 10-digit dialling is required for local calls within this region because the same 7-digit number can be assigned under either code.
Mobile numbers in 323 are portable: a person who moved away from Los Angeles may still carry a 323 mobile number on their device. If you receive an unexpected call from a 323 number, run it through the reverse lookup tool above for the most accurate, free identification.
If you live or do business in California, you may also interact with neighbouring or overlay codes (213). See the related codes section below to explore the rest of California.
