Robinson and Moon-area residents could be dialing up a new area code.
The Pennsylvania Public Commission is adding 878 as a new area code for southwestern Pennsylvania because the 724 and 412 phone numbers are almost all taken.
The 724 area code is nearing exhaustion and the need to activiate the 878 area code is imminent, according to the commission. Because of this, telephone numbers will be assigned using the 878 area code in the 724 area.
All current customers keep their same area codes and telephone numbers. Numbers from the new area code may be assigned to new telephone customers or those adding additional lines.
The 412 area code is primarily located in Pittsburgh and 724 covers the suburbs of Pittsburgh. The 878 area code is an overlay that covers both the 412 and 724 regions, according to the PUC website.
