Area Code 484 History:

Area code 835 has been approved as an all-services overlay of area codes 484 and 610 with an implementation date of 9/02/2022. Area code 835 will serve the same geographic area as area codes 484 and 610. Ten digit dialing (area code + seven digit number) will be necessary in the 434/610/835 overlay because different homes in the same geographic area can have the same seven digit phone number but each would have a different area code.
