About PhoneticAlphabet.org

An independent reference for the NATO/ICAO phonetic alphabet, the International Phonetic Alphabet, and Morse code — written for pilots, dispatchers, linguists, students, and anyone who has to spell something clearly out loud.

What this site is

PhoneticAlphabet.org is a free reference for the spelling alphabets used in radio, aviation, military, and emergency communications, alongside the linguistic notation used by phoneticians. The site is independent and is not affiliated with ICAO, NATO, the FAA, the ITU, the International Phonetic Association, or any government body.

The intent is narrow: provide a clear, accurate place to look up code words, pronunciations, and the standards behind them — without forcing readers through registration walls, paywalls, or interstitials.

Who it's for

The reference is written with a few audiences in mind:

  • Aviation: private and commercial pilots, ATC trainees, dispatchers, and ground crew who need standard phraseology.
  • Military and emergency services: service members across NATO forces, police and sheriff radio operators, fire and EMS dispatchers, and Coast Guard / maritime users.
  • Amateur radio: ham operators, contesters, and people studying for licensing.
  • Linguistics and education: students, language teachers, speech-language clinicians, and anyone learning IPA transcription.
  • Everyday communication: people spelling names, license plates, confirmation codes, or technical strings over the phone.

What's covered

NATO / ICAO phonetic alphabet

International Phonetic Alphabet (IPA)

  • The full IPA chart, plus dedicated breakdowns of vowels and consonants.
  • Place and manner of articulation, diacritics, and suprasegmentals.

Morse code

History and rationale

Editorial approach

Pages are written and reviewed against the underlying source material:

  • ICAO Document 9432 (Manual of Radiotelephony) for the ICAO/NATO alphabet and number pronunciations.
  • NATO STANAG 7085 for the standardized military alphabet.
  • FAA Order JO 7110.65 for US ATC phraseology and pilot readback conventions.
  • ITU Radio Regulations and the ITU-R M.1677 recommendation for International Morse Code.
  • The official chart and handbook of the International Phonetic Association for IPA symbols.
  • Published military and aviation communication manuals from the WWII period for the historical pages.

Where standards have changed over time — for example, regional variants of the alphabet before 1956 — pages explain what the older form was and where it persists today, rather than treating it as the current rule.

How content is produced

Content is written by the site's editor and cross-checked against the primary sources listed above. Pages are reviewed periodically; the date at the top of each substantive page reflects the most recent review. Corrections from readers are welcome and applied promptly when verifiable against an official source.

The site itself is a static set of HTML, CSS, and a small amount of JavaScript. There is no content management system, no comments section, no user-generated content, and no AI-generated images. The text-to-phonetic converter runs entirely in the browser — text typed into it is processed locally and is not sent to a server.

How the site is funded

PhoneticAlphabet.org is free to read and is supported by display advertising provided by Google AdSense. Ads help cover hosting and maintenance and let the reference stay open without paywalls or registration. Editorial content is independent of advertisers — pages are not sponsored, and ad placement does not influence what the site says about a topic.
