Call sign can refer to different types of call signs: Airline call sign Aviator call sign Cosmonaut call sign Radio and television call signs Tactical call sign, also known as a tactical designator See also: International Callsign Allocations, Maritime Mobile Service Identity This is a disambiguation page — a navigational aid...

A few countries do not fully comply with these rules. Australia drops the VL prefix for broadcast stations, and Canada uses Chile's CB for its own Canadian Broadcasting Corporation stations. The Canadian Broadcasting Corporation (CBC), a Canadian crown corporation, is the countrys national radio and television broadcaster. ...

With regard to the second and/or third letters in the prefixes in the list below, if the country in question is allocated all callsigns with A to Z in that position, then that country can also use call signs with the digits 0 to 9 in that position. For example, the United States is assigned KA–KZ, and therefore can also use prefixes like KA1 or K5.

Many large countries in turn have internal rules on how and where specific subsets of their callsigns can be used (such as Mexico's XE for AM and XH for FM broadcasting), which are not covered here.
