Some jurisdictions require a fee to obtain such a vanity call sign in others, such as the UK, a fee is not required and the vanity call sign may be selected when the license is applied for. In some countries, an operator may also select their own 'vanity' call sign that conforms to local laws. Each country must only assign call signs to its nationals or operators under its jurisdiction that begin with the characters allocated for use in that country or its territories. These prefixes are agreed upon internationally, and are a form of country code. Prefixes are assigned internationally, and a separating numeral plus suffix are added by a national body to produce this unique identifier. Call signs meant for amateur radio follow the ITU's Article 19, specifically 19.68 and 19.69. Since 1927 these have been used to uniquely identify operators and locate amateur stations within a geographical region or country of the world. The International Telecommunication Union (ITU) allocates call sign prefixes for radio and television stations of all types. The call signs are used to legally identify the station or operator, with some countries requiring the station call sign to always be used and others allowing the operator call sign instead. Amateur radio call signs are allocated to amateur radio operators around the world.
