NATO Phonetic Alphabet Converter
Convert text into the NATO (ICAO) phonetic alphabet — each letter becomes its code word (A=Alpha, B=Bravo…) and each digit its number word. Spaces are marked [space] and other characters are bracketed.

The NATO Phonetic Alphabet Converter turns any text into its spoken spelling using the internationally recognised NATO (ICAO) phonetic alphabet. Type a word, a name, a serial number or a whole sentence, and each letter is replaced with its code word — A becomes Alpha, B becomes Bravo, and so on — so it can be read aloud clearly over a radio or a phone line without confusing similar-sounding letters like "M" and "N" or "B" and "P".
How to use it
- Enter your text in the Text to Convert box.
- The NATO Phonetic Alphabet output updates automatically as you type.
- Copy the result or download it as a text file.
Letters are case-insensitive (a and A both become Alpha). Digits 0–9
are spelled out too. A space in your text is shown as [space], and any other
character (punctuation, symbols) is wrapped in square brackets, e.g. - becomes
[-]. This keeps the spoken version unambiguous when read back.
The full NATO phonetic alphabet
| Letter | Code word | Letter | Code word | Letter | Code word |
|---|---|---|---|---|---|
| A | Alpha | J | Juliet | S | Sierra |
| B | Bravo | K | Kilo | T | Tango |

Digits
| 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|---|---|---|---|
| Zero | One | Two | Three | Four | Five | Six | Seven | Eight | Niner |
Note that "9" is spoken as Niner — a deliberate change from "nine" so it is not mistaken for the German "nein" or lost in radio static.
Why use the NATO phonetic alphabet?
Spelling things out letter-by-letter is error-prone: over a noisy channel, "F" and "S" or "T" and "D" sound almost identical. The NATO alphabet assigns each letter a distinct, multi-syllable word chosen so that no two are easily confused. It is used by aviation, the military, emergency services, and call centres worldwide when relaying names, confirmation codes, licence plates or passwords by voice.
Is my text private?
Yes. The conversion runs entirely in your browser — nothing you type is sent to a server, so it is safe to spell out names, reference numbers or other sensitive details.
