How many area codes are in los angeles?

Los Angeles telephone numbers: 213, 310, 424, 661, 818, and 323 local area codes. To make an incoming international call (or a domestic long-distance call) to a Los Angeles landline or mobile phone, you must dial the appropriate 3-digit area code, followed by a 7-digit local subscriber number. The Los Angeles metropolitan area is very large and includes Long Beach, Glendale, Santa Clarita, Pomona and Palmdale, among other places. To meet the demand for new telephone numbers, Los Angeles has added “overlapping” area codes, meaning that, as new phone numbers are needed, a new area code is added within the space of existing area codes.
