发帖数: 4860 | 5 Telephone numbers with the prefix 555 are widely used for fictitious
telephone numbers in North American television shows, films, video games,
and other media, although real numbers do exist in this range.
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; the other numbers have been
reserved for actual assignment, with the notable exception of the 800 area
code where only 800-555-0199 is reserved. The entire 555 exchange is
reserved in all overlay North American toll-free area codes (844, 855, 866,
877, 888)[1] and in Canada's rarely used non-geographic area code 600.
Area code 555 in the North American Numbering Plan is reserved for Directory
Assistance applications.
