Updated Jan 02, 2010Area Code 925
"E" is Eastern Time Zone, "C" is Central Time Zone, "M" is Mountain Time Zone, and "P" is Pacific Time Zone. Occasionally, an area code will fall in more than one time zone. In this case, the abbreviation is a combination of the previous abbreviations. Some area codes are shown with time zones referencing Universal Coordinated Time (UTC). Additional technical status can be retrived from the North American Numbering Plan Administration on the 925 area code specific link here.
Area Code 925 ( area code map)
Dates and historical information Area code 925 went live into service on March 14, 1998.  It was formed as a subdivision of the 510 area code.
Growth Status Due to popularity, this area code is starting to run out of free telephone numbers for people to use which means that this area code is technically referred to as being "in jeoparady." Planning is underway and notices have been distributed regarding the area code subdivision.
Technical Status 2 Area code 925 is currently live and in service.
