HARRISBURG, Pa. — A new area code is bringing 10-digit dialing to residents of 16 southcentral Pennsylvania counties.
The new 223 area code is being added Saturday to the area covered by the 717 area code. That’s because the amount of numbers available under the 717 area code is almost exhausted.
The 717 area, which includes the state capital of Harrisburg, is one of the last in the state to make the switch.
Residents in the Philadelphia area, which used to be served only by the 215 area code, have been dialing 10 digits since the 610 area code was added in that area 18 years ago.
The Pennsylvania Public Utility Commission says folks should update medical alert systems, burglar alarms and other devices that use the old seven-digit local phone numbers.
