Old Telephone Exchange Names
Los Angeles County

Photo courtesy of 526663 and Pixabay.com.

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. Below is a list of exchange names and numbers for Los Angeles County gleaned from the Telephone EXchange Name Project, compiled by Robert Crowe, and from recollections offered by visitors to the Los Angeles Almanac. The list is not exhaustive nor do we guarantee absolute accuracy. Information collected from personal recollections contributed may be imperfect. We will update and add any new exchange information as we come across them (or you tell us about them).

* UL or ULrich - A correspondant reported to us that "ULrich" was for dialing up the time of day. Any five numbers could be dailed after "UL" to hear a recording that offered the time, "At the tone, the time will be three twenty-five and thirty seconds." The time was updated every ten seconds.
