555 numbers came about in the 1960s; the first usage seems to have been 1961, after most seasons of Perry Mason had been broadcast. They don't seem to have become ubiquitous until the early 1970s.

TV Tropes says that

Another fake number used back in the 1950s through the 1970s when most of Southern California was entirely one area code, 213, was to reserve the extension 1 plus the prefix in every prefix, so that the number 462-1462 or 733-1733 was never a working number. . . . A number of TV shows and made-for-tv movies took advantage of this fictional number feature.


I'll have to listen for that.
