Updated Jan 02, 2010Area Code 301
  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 301 area code specific link here.

LocationMaryland
Dates and historical informationArea code 301 went live into service on January 01, 1947 (The paperwork process started on January 01, 1947).  It has had the 240, 410 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 240, 227 area codes to provide more telephone numbers in the area.  This means this original "parent" 301 area code has seen quite a bit of growth and as a result has been subdivided into 3 area codes over the years. Planning is underway and notices have been distributed regarding the area code subdivision. 
Technical Status 2Area code 301 is currently live and in service.
