The NATO phonetic alphabet is the most widely used set of clear-code words for communicating the letters of the latin alphabet. Although spelling alphabets are commonly called "phonetic alphabets", they are not phonetic in the sense of phonetic transcription systems such as the International Phonetic Alphabet.

To create the code, a series of international agencies assigned 26 clear-code words (also known as "phonetic words") acrophonically to the letters of the Latin alphabet, with the goal that the letters and numbers would be easily distinguishable from one another over radio and telephone. The words were chosen to be accessible to speakers of English, French and Spanish. Some of the code words were changed over time, as they were found to be ineffective in real-life conditions. In 1956, NATO modified the then-current set used by the International Civil Aviation Organization (ICAO): the NATO version was accepted by ICAO that year, and by the International Telecommunication Union (ITU) a few years later, thus becoming the international standard.

In print, these code words are commonly capitalized or written in all caps for visual salience. Alfa and Juliett are spelled that way to avoid mispronunciation by people unfamiliar with English orthography; NATO changed |X-ray to Xray for the same reason.[1] The code words for digits are their English names, though with their pronunciations modified in the cases of three, four, five, nine and thousand.

The code words have been stable since 1956. A 1955 NATO memo stated that:

It is known[citation needed] that [the spelling alphabet] has been prepared only after the most exhaustive tests on a scientific basis by several nations. One of the firmest conclusions reached was that it was not practical to make an isolated change to clear confusion between one pair of letters. To change one word involves reconsideration of the whole alphabet to ensure that the change proposed to clear one confusion does not itself introduce others.[2]
