About the NATO Alphabet Translator

This tool converts text to the NATO phonetic alphabet (also known as the ICAO radiotelephony alphabet) and back. Each letter is mapped to a code word designed to be clearly understood over radio or phone: A → Alpha, B → Bravo, C → Charlie, and so on. Digits 0–9 also have standard code words (Zero, One, Two, …). The alphabet was standardized by the International Civil Aviation Organization (ICAO) and is used worldwide by aviation, military, maritime, and emergency services.

Decode mode recognizes the code words (case-insensitive) and converts them back to the original characters. Words between spaces in the input become spaces in the decoded output, so word structure survives a round trip.

How it works

  • To NATO — Uppercases the input, walks each character, and emits the matching code word. Spaces between words become a single space; non-mapped characters pass through unchanged.
  • From NATO — Splits the input on whitespace, looks up each token (case-insensitive) in the reverse table, and rejoins. Unrecognized tokens are kept as-is so you can spot gaps in the input.
  • Supported character set: A–Z and 0–9. Punctuation and other symbols pass through unchanged in both directions.

How to use the translator

  1. Paste or type text (or NATO code words separated by spaces) in the input box.
  2. Click To NATO to encode text, or From NATO to decode code words.
  3. The result appears in the output box.
  4. Click Copy to copy the result, or Clear to start over.

Frequently asked questions

Does this tool upload my text? No. All conversion happens locally in your browser. Your text never leaves your device.

What is the NATO phonetic alphabet used for? It is used to spell out letters unambiguously over radio, telephone, or other voice channels where similar-sounding letters (like B and P, or M and N) might be confused.

Does it support languages other than English? The standard NATO alphabet covers A–Z and 0–9. Accented characters are not mapped and pass through unchanged.

How are word breaks represented? Spaces between words in the input are preserved as spaces in the output for both encoding and decoding directions.
