HARRISBURG – The PA Public Utility Commission announced the assignment of 835 as a new area code which will eventually serve the same geographic area in southeastern PA currently served by the 610 and 484 area codes. The 610/484 calling area serves residents and businesses in Berks, Chester Delaware, Lehigh, and Northampton Counties, along with a portion of Montgomery County. The remaining supply of available phone numbers in the 610/484 area is estimated to be exhausted in early 2023 – requiring the establishment of a new area code to support future demands in the region. No new 835 numbers will be assigned in the area until the remaining 610/484 numbers are completely exhausted. Because 10-digit dialing is already well established in this region, the eventual addition of the new 835 area code will not require any changes to the way area residents and businesses dial telephone calls – aside from using the new area code.
