Area code 835 is planned as an overlay for the existing 610 and 484 area codes in the Allentown, PA area and surrounding regions. Overlay Area Code: The 835 area code is designated as an overlay for the existing 610 and 484 area codes in Eastern Pennsylvania, which includes cities like Allentown, Bethlehem, and Reading. An overlay means that it will serve the same geographic area as the existing area codes. Purpose of Introduction: The introduction of area code 835 is intended to address the shortage of available phone numbers in the region due to increasing demand. As phone numbers become exhausted in the 610 and 484 areas, new phone numbers will be assigned the 835 area code. Impact on Dialing: With the introduction of the 835 overlay, 10-digit dialing (area code + phone number) becomes mandatory for all calls within this region. This means that even for local calls within the same area code, the full 10-digit number must be dialed. In conclusion, the 835 area code is a future addition to the Allentown, PA area, reflecting the growing need for more telephone numbers due to the expansion of residential and business services. Its implementation will ensure a continuous supply of phone numbers while maintaining the existing numbers in the region.
