5-5-5
In North American television shows and movies, 5-5-5 is the prefix used for fictional telephone numbers. In older television shows from the 1950s or 1960s, "KLondike 5" was used, as at the time the telephone exchanges used letters. "KLamath 5" is sometimes also used.The 5-5-5 prefix is almost always fictitious; no number in any NANP area code will begin with three 5's.
