Spelling alphabets

The NATO phonetic alphabet, officially the International Radiotelephony Spelling Alphabet, is an internationally recognized set of names for the letters of the Latin alphabet and the Hindu-Arabic digits. It is most commonly used in radio communication, where the usual names of the letters are likely to be misheard. It was defined in 1955–1956 by the International Civil Aviation Organization (ICAO).
