The
former telephone company GTE (merged into Verizon) once
inadvertantly published a
telephone directory for Sierra Madre
listing no home
numbers.
In 1958, due to increased consumer demand for individual
telephone numbers, the telephone company began phasing out old
exchange names for all numeric telephone numbers or "All Number
Calling" (pretty much gone by 1963). These old exchange
names are
remembered in Glenn Miller’s song PEnnsylvania 6-5000, and
Elizabeth Taylor’s movie BUtterfield-8.

Angeles County gleaned from exchange names collected by the
