Call signs in North America

==Canada==
{{main|Call signs in Canada}}
Canadian broadcast stations are assigned a three-, four-, or five-letter base call sign (not including the "-FM", "-TV" or "-DT" suffix) beginning with '''CB''', '''CF''', '''CH''', '''CI''', '''CJ''', '''CK''', '''VF''', or '''VO'''. The "CB" series calls are assigned to [[Chile]] by the ITU, but Canada makes [[de facto]] use of this series anyway for stations belonging to, but not exclusively broadcasting programs from, the [[Canadian Broadcasting Corporation]] (CBC).<ref>{{Cite web |url=http://www.dxinfocentre.com/wx-fm.htm# |title=DXinfocentre.com |access-date=2006-05-26 |archive-url=https://web.archive.org/web/20070210194402/http://www.dxinfocentre.com/wx-fm.htm# |archive-date=2007-02-10 |url-status=dead }}</ref>

Several other prefixes, including '''CG''', '''CY'''-'''CZ''', '''VA'''-'''VE''', '''VG''', and the '''XJ'''-'''XO''' range, are available, but are not used in broadcasting. Conventional radio and television stations almost exclusively use "C" call signs; with the exception of a few commercial radio stations in [[St. John's, Newfoundland and Labrador]] which existed prior to the admission of Newfoundland as a province in 1949, the "V" calls are restricted to specialized uses such as [[amateur radio]].
