Area code 415


(c) Copyright 2010 ReversePhoneCheckc.com. All Rights Reserved

Area code 415 was created in 1947 and is used as the telephone area code for several areas of Bay Area -- California. At that time, it was covering:

  •     Southern areas of area code 916
  •     Northern areas of the area code 213.

However in 1950, certain changes were made to the geographic boundaries of area 916 and it was reduced to the north-eastern corner of the state. On the other hand, area code 415 was expanded from northern areas to the contiguous areas of Oregon border.

Area code 415 split again into two new area codes on 1st March 1959. Code 707 was allocated to areas of the North Bay (excluding Marin County) and code 408 was allocated to the areas of South Bay.

Demands for telephone lines were increasing day by day and in order to facilitate the customers resourcefully area code 415 got split again on 2nd September, 1991. This time code 510 was assigned to the areas of Oakland and the East Bay.

A new area code 650 was created on 2nd August, 1997 as a result in splitting of area code 415. The new code was created to serve the areas of San Francisco. Marin County and certain areas of Brisbane and Daly City is using area code 415 and the remaining areas towards south are assigned with code 650.

Other area codes which are being used in different areas of Bay Area are:

  •     Area Code 510 (created in 1991)
  •     Area Code 408 (created in 1959)
  •     Area Code 707 (created in 1959)
  •     Area Code 925 (created in 1998)

Why Do Areas Split?


When the volume of telephone numbers in an existing area gets exhausted, the phone company splits the existing areas and assigns new code to some of its exchanges.

It's not splitting of area - however it's all about the exchanges of particular area which are being divided geographically. Areas are divided into two parts: one retain existing code while the other is assigned with newer one. Creating new codes in existing area make it possible to provide telephone services more efficiently and resourcefully.
