Area Code 878

Area code 878 ' telephone area code occupied by Pittsburgh Region of Pennsylvania. Pennsylvania is Middle Atlantic State of United States using Eastern Time Zone.

Code 878 was created on 17th August, 2001. It is an overlay area code for codes 724 and 412. After that, ten digit dialing became obligatory in the 412 and 724 areas of Western Pennsylvania.

Introducing new area code onto existing area that is already engaged by one or more area code is called adding an overlay. By adding overlay one area is served by two or more area codes. Demand for new phone numbers is increasing day by day because of the increase in use of mobile phones and land line numbers. Areas are either split or added as overlay in order to fulfill the exhausted demands for phone numbers.

However, area code split creates several business or administrative problems for customers, such as changes in stationery, marketing, and remembering the number change among friends and clients. On the other hand, overlay has no affect on existing numbers while new numbers are issued with new area code assigned to overlay area. But it becomes mandatory to dial ten-digit number even while making local phone calls.
