What is the NATO phonetic alphabet?

The NATO phonetic alphabet is a set of 26 code words - one for each letter of the English alphabet - that lets people spell things out clearly over voice channels. Instead of saying the ambiguous letters B and D, which sound almost identical on a crackly phone line, you say Bravo and Delta, which cannot be confused. Its formal name is the International Radiotelephony Spelling Alphabet, and it is the standard used by NATO, by the International Civil Aviation Organization (ICAO) for aviation, and by the ITU for telecommunications.

The full set runs 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, and Zulu. The words were chosen and tested so that speakers of many different languages could pronounce and recognise them, which is why a couple are respelled - Alfa with an f and Juliett with a double t. Digits have spoken forms too, including the well-known Niner for nine.

How to use this translator

Type or paste any text into the box on the left - a name, a postcode, a booking reference, or a serial number. The phonetic spelling appears instantly on the right. Each letter is replaced by its code word regardless of case, each digit becomes its spoken number, and spaces between words are shown as a (space) marker so you know where one word ends. Switch on Show as list to get one code word per line, which is handy when reading slowly to someone, or leave it off for a compact inline result. Tick Read out letters to have your browser speak the code words aloud using built-in speech synthesis. Press Copy to grab the result or Clear to start again.

When is it used?

Pilots and air traffic controllers use the phonetic alphabet constantly for call signs, runway identifiers, and clearances, where a single misheard letter could be dangerous. The military relies on it for radio traffic and map references. Closer to everyday life, call-centre agents, IT support, banks, and emergency dispatchers use it to confirm names, account numbers, and codes without error. It is also the quickest way to spell your own name over the phone - say "Sierra, Alfa, Mike" and there is no doubt you mean Sam. Anyone reading out a confirmation code, licence plate, or password reset reference can avoid the classic "was that an M or an N?" back-and-forth.

Frequently Asked Questions

Why is it spelled Alfa and Juliett instead of Alpha and Juliet?
The NATO and ICAO standard deliberately respells two words to avoid confusion for speakers of many languages. Alpha is written Alfa because the ph spelling is not pronounced as an f sound in some languages, so the f spelling keeps the pronunciation consistent worldwide. Juliet is written Juliett with a double t so that French speakers, who would otherwise drop a single final t, still pronounce the ending. These small respellings are part of the official code and are intentional, not typos.
Why is nine said as Niner?
In radio and aviation communication, the digit nine is pronounced Niner to keep it from being confused with the German word nein, which means no, and to stop it sounding like the word five over a noisy or distorted radio link. Adding the extra syllable makes nine clearly distinct from other numbers. Several digits get this treatment in aviation: three is often said as tree and four as fower for the same clarity reasons, though nine to Niner is the most widely known.
Is the NATO phonetic alphabet the same as the military alphabet?
Yes. The phrase military alphabet almost always refers to this same set of code words: Alfa, Bravo, Charlie, and so on. It is formally called the International Radiotelephony Spelling Alphabet, adopted by NATO, the ICAO for aviation, and the ITU. Earlier militaries used different spelling alphabets, such as the World War II Able, Baker, Charlie set, but those have been retired. Today the NATO, ICAO, and standard military spelling alphabets are one and the same.
How do I use the phonetic alphabet to spell my name over the phone?
Spell your name one letter at a time and replace each letter with its code word. For example, the name Sam becomes Sierra Alfa Mike. Type the name into the box above and the tool produces the spelling instantly so you can read it aloud. This is the clearest way to give a name, booking reference, postcode, or confirmation code to a call-center agent, because code words like Bravo and Delta cannot be mistaken for one another the way the letters B and D can.
What happens to numbers, spaces, and punctuation?
Digits are converted to their spoken forms, so 0 becomes Zero, 5 becomes Five, and 9 becomes Niner. Spaces between words are shown as a (space) marker so you can tell where one word ends and the next begins. Letters are matched without regard to case, so a and A both map to Alfa. Any other punctuation, such as a hyphen or full stop, is passed through unchanged so you do not lose it from your message.
Does this translator send my text anywhere?
No. The translation runs entirely in your browser using JavaScript, so the text you type is never uploaded, stored, or tracked. The optional read-aloud feature uses your browser's built-in speech synthesis and also works locally. Once the page has loaded you can use the tool offline, and refreshing or closing the page clears everything. Your words stay on your own device from start to finish.
