> The NATO phonetic alphabet translator spells out text with the international radiotelephony spelling alphabet – Alfa, Bravo, Charlie … – and translates code words back into letters and numbers.

## Inputs

- Translate
- Text

## Results

- Translation
- Characters (without spaces)

## Formula

```
Each letter A–Z becomes its ICAO/NATO code word (Alfa, Bravo, Charlie …); digits become Zero … Nine; spaces are shown as (space)
```

## Explanation

The phonetic alphabet was standardised by ICAO and NATO in the 1950s so that letters can be understood clearly over noisy radio and telephone lines, even by speakers of different languages. It is used by pilots, the military, police and customer service – for example to spell out booking references. Note the official spellings "Alfa" and "Juliett". Everything is calculated in your browser, so nothing you type is sent to our server.

## FAQ

**Why is it spelled "Alfa" and "Juliett"?**
So that speakers of other languages pronounce them correctly – "ph" and a single "t" can be misread.

**Is "niner" correct for 9?**
Aviation radio often says "niner" to avoid confusion with the German "nein"; both are understood.

**What is the difference between NATO and ICAO alphabets?**
They are the same 26 code words, adopted by both organisations.

**What formula does the NATO Phonetic Alphabet Translator use?**
Each letter A–Z becomes its ICAO/NATO code word (Alfa, Bravo, Charlie …); digits become Zero … Nine; spaces are shown as (space).
