Question:
Why is the prefix 555 used for phone numbers on TV programs and in movies?
Answers:
In North America, telephone numbers with the prefix 555 are widely used for fictitious phone numbers in television shows, films, computer games, and other media.
Not all numbers that begin with 555 are fictional—for example, 555-1212 is one of the standard numbers for directory assistance throughout the United States and Canada. In fact, only 555-0100 through 555-0199 are now specifically reserved for fictional use, with the other numbers having been released for actual assignment.
The phone companies asked the television and movie directors to stop using real phone numbers because people kept calling them and irritating the people with those numbers and clogging up switchboards with nuissance calls.
