Frequently Asked Questions
What is the NATO phonetic alphabet?
The NATO phonetic alphabet is a standardized set of 26 code words — Alfa, Bravo, Charlie, and so on — used to spell out letters unambiguously over radio and telephone. Formally designated the ICAO/ITU Radiotelephony Spelling Alphabet, it was adopted in 1956 and remains the global standard for aviation, military, maritime, emergency services, and telecommunications.
Why is it called "Alfa" and not "Alpha"?
The spelling Alfa was chosen because "ph" is not universally pronounced as /f/ in all languages. By using "f" directly, ICAO ensured correct pronunciation across all language backgrounds.
Why does "Juliett" have two T's?
French speakers commonly drop a final silent consonant. A single "t" in Juliet could be swallowed, making it sound like Julie. The double "t" forces clear pronunciation of the ending, preventing confusion over noisy channels.
Is the phonetic alphabet the same as the IPA?
No. The NATO phonetic alphabet is a spelling alphabet (code words for letters). The International Phonetic Alphabet (IPA) is a system of symbols representing speech sounds. They serve entirely different purposes. See the full IPA chart →
Do police use the same phonetic alphabet?
Not always. Many US law enforcement agencies use the APCO phonetic alphabet (Adam, Boy, Charles…), though NATO/ICAO is gaining adoption. Compare them here →
