NATO Phonetic Alphabet Converter
Type any word and instantly get its NATO phonetic spelling — letters become Alpha, Bravo, Charlie and digits are spelled out — so it is unmistakable over the phone or radio.
How to use NATO Phonetic Alphabet Converter
The NATO Phonetic Alphabet Converter transforms any text into the internationally standardised spelling alphabet used by aviation, military, maritime, and emergency services — where each letter becomes a distinct code word (Alpha, Bravo, Charlie) and each digit is spelled out (Zero through Nine). This eliminates confusion between similar-sounding letters over noisy radio, phone, or VoIP channels. All conversion runs in your browser; nothing is transmitted.
- Type or paste the text you want to spell out into the input area.
- Each letter is instantly mapped to its NATO/ICAO code word (A → Alpha, B → Bravo, etc.).
- Digits are spelled out as words (0 → Zero, 1 → One, etc.) for unambiguous reading.
- Spaces between words appear as separators so you can see word boundaries clearly.
- Copy the phonetic output with the Copy button for use in call scripts, emails, or training materials.

The full NATO phonetic alphabet
The NATO phonetic alphabet — formally the International Radiotelephony Spelling Alphabet — was adopted by NATO in 1956 and is also endorsed by ICAO, the ITU, and the IMO. Each code word was chosen after extensive testing across speakers of different languages to minimise misidentification. The words are deliberately multi-syllabic and phonetically distinct: "Foxtrot" cannot be confused with "Golf," and "November" stands apart from "Oscar." The same alphabet is used globally by air-traffic controllers, police dispatchers, call-centre agents, and IT support teams spelling out serial numbers, email addresses, and confirmation codes.
| Letter | Code word | Letter | Code word |
|---|---|---|---|
| A | Alpha | N | November |
| B | Bravo | O | Oscar |
| C | Charlie | P | Papa |
| D | Delta | Q | Quebec |
| E | Echo | R | Romeo |
| F | Foxtrot | S | Sierra |
| G | Golf | T | Tango |
| H | Hotel | U | Uniform |
| I | India | V | Victor |
| J | Juliet | W | Whiskey |
| K | Kilo | X | X-ray |
| L | Lima | Y | Yankee |
| M | Mike | Z | Zulu |
When and why to use phonetic spelling
Phonetic spelling is essential whenever letters must be communicated unambiguously over an audio-only channel. Over the phone, B and D sound nearly identical, as do M and N, S and F, or P and T. In noisy environments — airports, construction sites, military operations — even clearly spoken letters can be swallowed by background noise. Using code words ("Bravo" for B, "Delta" for D) eliminates this class of error entirely. Beyond voice communication, phonetic spelling is standard in data-entry verification, customer-support call scripts, and any scenario where a single misheard character could cause a costly mistake — booking codes, licence plates, prescription numbers, and security credentials.
