26 codewords · pronunciation · word origin · text converter

The NATO phonetic alphabet — officially the International Radiotelephony Spelling Alphabet — assigns 26 codewords, Alfa through Zulu, to the letters A–Z so spelling survives noisy radio links. Adopted by ICAO in 1956, it is the standard spelling alphabet for NATO, aviation, maritime and emergency services worldwide.

Usage Rules

Three rules: Accuracy — exact codeword, no shortcuts. Brevity — under 30 seconds. Clarity — enunciate each syllable.

Decimal = "DECIMAL" · Period = "STOP" · Never say "REPEAT" — say "SAY AGAIN"

History

ICAO tested each word against noise, interference, and 31 language groups. Alfa (not Alpha) — prevents Spanish/Portuguese mispronunciation. Juliett (double-T) — forces French speakers to pronounce the final consonant. Niner (not Nine) — avoids confusion with German "nein" (no).

Frequently Asked Questions

Why is it spelled Alfa and not Alpha?

ICAO uses the spellings Alfa and Juliett deliberately: 'ph' is not pronounced 'f' in many languages, and a single-t Juliet could be misread by French speakers. The altered spellings force the correct pronunciation.

Is the military alphabet the same as the NATO phonetic alphabet?

Yes. 'Military alphabet' is the informal name for the NATO phonetic alphabet (officially the International Radiotelephony Spelling Alphabet), standardized in 1956 and used by NATO forces, ICAO aviation and emergency services.

What is the NATO phonetic alphabet in order from A to Z?

Alfa, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliett, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu.

How are numbers pronounced in the NATO alphabet?

Digits are spoken individually with modified pronunciations for clarity: 3 is 'tree', 4 is 'fower', 5 is 'fife' and 9 is 'niner' — so 1945 is spoken 'wun niner fower fife'.

Who uses the NATO phonetic alphabet?

NATO militaries, civil aviation (ICAO), maritime services, amateur radio operators, police and emergency dispatch in many countries, and call centers spelling names, emails and booking references over the phone.

What alphabet was used before the NATO alphabet?

The Able Baker alphabet (Able, Baker, Charlie, Dog...) used by US and UK forces through WWII. It was too English-centric, so ICAO developed the current alphabet, finalized in 1956 after testing across 31 language groups.

How do I spell an email address over the phone?

Spell each letter with its codeword: 'john@' is Juliett, Oscar, Hotel, November, at-sign. Say 'dot' for periods, 'dash' for hyphens, 'underscore' for _, and 'capital' before uppercase letters.
