Philadelphia metropolitan region information


This table lists all the three-digit numeric prefixes used in the 215 area as it was constituted prior to the splitting off of the 610 area in the 1990s, with a cross-reference to the appropriate area table within the region.

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.)

NOTE 1: This exchange may have had the specified name only unofficially; it is rather likely that it was instituted after the general switch to All-Number Calling, and officially just given the all-number designation, but the exchanges given this note could be unofficially designated by the names shown in this table.

NOTE 2: Although the dates of starting and ending these exchanges are unknown:

NOTE 3: The WIssahickon 7 exchange was discontinued some time after 1954 but before approximately 1958. The WIlson 7 exchange was started approximately 1960, but definitely after the end of the WIssahickon 7 exchange.
