NATO Phonetic Alphabet Translator

The NATO phonetic alphabet — formally the International Radiotelephony Spelling Alphabet, standardized by ICAO in 1956 — assigns a code word to each letter to prevent confusion between similar-sounding letters (B/D, M/N, S/F) when spelling over radio or phone.

The 26 code words: Alpha, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliet, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu. Numbers use standard English words (Zero through Nine).

Used by military, aviation (air traffic control), maritime, emergency services, police, and anyone spelling out serial numbers, order codes, or names over bad phone connections. Paste any text and instantly get the NATO spelling for every character.

The code words were not chosen casually — candidates were tested on speakers of English, French and Spanish, under real radio noise, and a word only made the list if it survived being shouted through static in several accents. Two official spellings still surprise people: the standard writes 'Alfa' and 'Juliett', not 'Alpha' and 'Juliet' — 'Alfa' so that non-English speakers don't misread 'ph', and the double-t so French speakers don't treat a final silent t.

Aviation bends the numbers too. Over the radio, pilots and controllers say 'niner' for 9 (so it can't be confused with the German 'nein' or lost next to 'five'), and many say 'tree' for 3 and 'fife' for 5 — official ICAO pronunciations designed for clarity through distortion, not elegance.

Before 1956, Allied forces spelled with the 'Able Baker' alphabet (Able, Baker, Charlie, Dog…), and the RAF of the First World War used older signalese — 'Ack' for A survives in the phrase 'ack-ack' for anti-aircraft fire. The modern list replaced them all precisely because it was the first alphabet engineered to work internationally — which is also why it turns up far from any cockpit: call centres, pharmacies and booking desks spell confirmation codes with it every day.
