Understanding Area Code 878: Location, History, and Usage

Area code 878 is a relatively new addition to the North American Numbering Plan (NANP), having been activated in 2013. As a result, many people may not be familiar with this area code, its location, history, and usage. In this article, we will explore all of these aspects of area code 878.

Location

Area code 878 is an overlay for the 412 and 724 area codes in western Pennsylvania, which includes the cities of Pittsburgh, Erie, and Greensburg. An overlay is a type of numbering plan that allows more than one area code to be assigned to the same geographic region. This is done to provide additional telephone number capacity without requiring customers to change their existing phone numbers.

History

The North American Numbering Plan (NANP) was established in 1947 to simplify the dialing of long-distance telephone calls within the United States and Canada. At that time, area codes were assigned based on geographic regions, with larger metropolitan areas receiving the lowest numbers. Over time, as the demand for telephone numbers increased, new area codes were added to existing regions, and some regions were split into multiple area codes.

In the case of area code 878, it was created to provide additional telephone number capacity for the western Pennsylvania region served by the 412 and 724 area codes. The overlay was chosen over a split because it allowed customers to keep their existing phone numbers and avoided the need for them to update their contact information.

Usage

Area code 878 is used for both landline and mobile phone numbers in the western Pennsylvania region. As an overlay, it does not change the way that calls are dialed, but it does require callers to dial the full 10-digit phone number (area code + local number) for all calls within the 878, 412, and 724 area codes. This is known as mandatory 10-digit dialing and is necessary to ensure that calls are routed correctly to their intended destinations.

Conclusion

In conclusion, area code 878 is an overlay for the 412 and 724 area codes in western Pennsylvania. It was created in 2013 to provide additional telephone number capacity without requiring customers to change their existing phone numbers. As an overlay, it is used for both landline and mobile phone numbers and requires mandatory 10-digit dialing for all calls within the 878, 412, and 724 area codes.
