Updated Jan 02, 2010Area Code 815
  1. "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).
  2. Additional technical status can be retrived from the North American Numbering Plan Administration on the 815 area code specific link here.
Area Code815 (area code map)
LocationIllinois
Dates and historical informationArea code 815 went live into service on January 01, 1947 (The paperwork process started on January 01, 1947).  It has had the 779 area code(s) overlaid on it.
Growth StatusThis original "parent" area code went live on January 01, 1947 and due to growth it has been "overlaid" by the 779 area code to provide more telephone numbers in the area.  This means this original "parent" 815 area code has seen quite a bit of growth and as a result has been subdivided into 2 area codes over the years. 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."  
Technical Status 2Area code 815 is currently live and in service.
