240 AREA CODE

The 240 area code applies to phone numbers from the state of Maryland. To learn more about the 240 area code, go to http://en.wikipedia.org/wiki/Area_code_240

Area codes were introduced in the United States by the Bell Systems, in 1947. The first direct dial long distance phone call occurred in 1951.

Area codes are also known as Numbering Plan Areas (NPAs) and formerly known as STD codes in the UK. These are necessary (for the most part) only when dialed from outside the code area, from mobile phones, and (especially within North America) from within overlay plans.

Area codes usually indicate geographical areas within one country that are covered by perhaps hundreds of telephone exchanges, although the correlation to geographical area is becoming obsolete.

The area code is usually preceded in the dial string by either the national access code ("0" for many countries, "1" in USA and Canada) or the international access code and country code.
