About NATO Phonetic Alphabet
The NATO Phonetic Alphabet Converter turns any text into the ICAO/NATO spelling alphabet — A becomes Alfa, B becomes Bravo, C becomes Charlie — so you can read out confirmation codes, license plates, serial numbers, or your name over a noisy phone line without being misheard. Digits are spoken as words, with 9 read as Niner, and spaces are preserved so a round-trip stays intact. Switch to decode mode to paste code words like Sierra Oscar Sierra and recover the original letters. It is handy for pilots, radio operators, support agents, and anyone reading strings aloud. Everything runs locally in your browser, so the names and codes you type stay on your device.
Features
- Spell any text as NATO code words — Alfa, Bravo, Charlie through Zulu
- Speaks digits as words and uses the ICAO Niner for the number nine
- Decode mode turns pasted code words back into plain letters and digits
- Case-insensitive input; output uses the canonical capitalized spellings
- Marks spaces so a text to NATO and back conversion round-trips exactly
- Keeps unrecognized characters as-is instead of silently dropping them
- Copy the result with one click for a script, ticket, or radio log
- Runs entirely in your browser with nothing uploaded
How to use the NATO Phonetic Alphabet

Example
Input
SOS
Output
Sierra Oscar Sierra
Each letter maps to its ICAO code word; S is Sierra, O is Oscar.
Common errors & troubleshooting
- Decoded text runs the words together with no spaces. — Include the (space) marker between groups of code words — the converter adds it automatically when you encode, and decode restores each one as a space.
- A code word comes back unchanged in the decoded output. — Check the spelling against the standard set; the tool passes an unrecognized word through verbatim rather than guessing, so a typo like 'Alpha' should be 'Alfa'.
- The number nine decodes oddly when someone wrote it as 'Nine'. — The ICAO standard spelling is 'Niner' to avoid confusion; use Niner for 9 so it round-trips through this tool.
Frequently asked questions
- How do I spell my name in the NATO phonetic alphabet?
- Type your name in the Text → NATO box and the converter spells each letter — so 'ANN' becomes 'Alfa November November'. Read the code words aloud or copy them for a call or form.
- Why does this tool spell nine as Niner?
- Niner is the ICAO/NATO reading for the digit 9. It is deliberately distinct from 'nein' and other words so it survives a noisy radio or phone line, and this converter uses it for both encoding and decoding.
- Can I decode NATO code words back into normal text?
- Yes. Switch to the NATO → Text tab and paste words like 'Sierra Oscar Sierra'. The converter is case-insensitive and rebuilds the original letters, digits, and spaces.
- What happens to punctuation and unknown characters?
- A few common marks map to spoken words (a period becomes Stop, a slash becomes Slash), and any other character is kept exactly as typed so nothing is lost when you convert text to NATO.
- Is this the same as the military or aviation alphabet?
- Yes — the NATO, ICAO aviation, and military spelling alphabets are the same 26 code words (Alfa through Zulu), which is exactly the set this converter uses.
- Do the names and codes I spell out stay private?
- Yes. The NATO Phonetic Alphabet Converter runs entirely in your browser, so the text you spell or decode never leaves your device and nothing is uploaded to ArrayKit.
