Philadelphia suburban telephone exchanges after July 5, 1946



This section is organized in the same way as is each geographical section of this site: by exchange. There are three tables, which can be described as alphabetical, numeric, and alphabetical/numeric:

Unlike many other cities, in Philadelphia and the rest of the 215 area, even after the start of All-Number Calling many exchanges were assigned to the same area that had others beginning with the same two digits, so that they could be thought of (and apparently were thought of) as within the same exchange name as existing exchanges with the same first two digits. These "unofficial" names are given here, with a note to indicate that they were not official. (In fact, some of these names may have been official; this is not totally certain.)
