The International Telecommunication Union (ITU) allocates call sign prefixes for radio and television stations of all types. They also form the basis for, but do not exactly match, aircraft registration identifiers. These prefixes are agreed upon internationally, and are a form of country code. A call sign can be any number of letters and numerals but each country must only use call signs that begin with the characters allocated for use in that country.
Call signs are frequently still used by North American broadcast stations, in addition to amateur radio and other international radio stations that continue to identify by call signs around the world. Each country has a different set of patterns for its own call signs. Call signs are allocated to ham radio stations in Barbados, Canada, Mexico and across the United States.
Station identification is the practice of radio or television stations or networks identifying themselves on-air, typically by means of a call sign or brand name. This may be to satisfy requirements of licensing authorities, a form of branding or a combination of both. As such, it is closely related to production logos, used in television and cinema alike.

Call signs in New Zealand are no longer generally used to identify broadcast stations. However, New Zealand's radio stations were once known by their call signs and would usually broadcast their call signs as a number followed by X, Y, or Z, and another letter. Call signs are regulated internationally by the ITU and nationally by the Ministry of Business, Innovation and Employment (MBIE), formerly the Ministry of Economic Development. The ministry is also responsible for providing policy advice to Government on the allocation of New Zealand's radio spectrum to support, efficient, reliable and responsive wireless telecommunications and broadcasting infrastructure.
Call signs in Australia are allocated by the Australian Communications and Media Authority and are unique for each broadcast station. The use of callsigns on-air in both radio and television in Australia is optional, so many stations used other on-air identifications. Australian broadcast stations officially have the prefix VL- and originally all callsigns used that format, but since Australia has no nearby neighbours, this prefix is no longer used except in an international context.

Broadcast call signs are call signs assigned as unique identifiers to radio stations and television stations. While broadcast radio stations will often brand themselves with plain-text names, identities such as "cool FM", "rock 105" or "the ABC network" are not globally unique. Another station in another city or country may have a similar brand, and the name of a broadcast station for legal purposes is normally its internationally recognised ITU call sign. Some common conventions are followed around the world.
