Code 408, 707 and 925 are the codes used beside code 415 and code 510 in different areas of Bay Area ? California.

Why do existing areas need area code divisions?

The idea is to 'divide and rule' - it is easy to manage smaller areas. Additionally it becomes easier to provide additional telephone lines required by customers. Same telephone numbers can be repeated in two different areas but with different area codes. This is how the task of assigning new numbers to customers becomes quick and efficient within particular area.

Existing areas need new area code when it becomes almost impossible to accommodate exhausted demands for telephone lines. Areas get exhausted when there is lack of available phone numbers. To overcome the problem areas are split into further smaller areas. Each newly created area is assigned with new and unique code. In this way areas can be provided with more and more available phone numbers.  

Standard time for these areas is Pacific Time zone and database of all registered phone numbers is compiled into California Phone Directory. Other area codes which are being used in different areas of Bay Area are:

• Code 415 (created in 1947)
• Code 408 (created in 1959)

• Code 925 (created in 1998)
