The California Public Utilities Commission has approved area code 738 as an all services overlay of area codes 213 and 323. Area code 738 will only become available to subscribers when all assignable central office codes in area code 213 and 323 are assigned. The earliest date area code 738 will be put into service is November 1, 2024. Ten digit dialing (area code + seven digit number) will be necessary in the 213/323/738 overlay because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
