Outer 215 Area telephone exchanges
Under this heading are currently included all exchanges that were assigned the
215 area code when area codes were instituted, but were outside the dialing
area of the city of Philadelphia. All the
exchanges in this section were, during the period in question, in the 215 area,
though subsequently a division into 215 and 610 took place. (Subsequently,
additional area codes were established, but by overlaying, so that none of the
exchanges listed in the "metropolitan Philadelphia" portions of this site went
into any area other than 215 and 610.)
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
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:
- In the alphabetical table, the exchanges are strictly ordered by the
alphabetical sequence of their exchange names. For example, COlony precedes
COngress, even though they may be dialed as COlony 8 (268) and COngress 4
- In the numeric table, the exchanges are strictly ordered by the
numeric sequence of the digits, so 264 (COngress 4) precedes 268 (COlony 8),
not to mention that 249 (CHerry 9) precedes 273 (BRidge 3).
- In the alphabetical/numeric table, the exchanges are strictly
ordered by the sequence of two letters and one digit associated with the
exchange, so that CO 4 precedes CO 8, but BR 3 precedes CH 9.
