NATO Phonetic Alphabet Translator

The NATO Phonetic Alphabet Translator converts ordinary text into the NATO spelling alphabet, replacing each letter with a distinct code word: A becomes Alfa, B becomes Bravo, C becomes Charlie, and so on through Z for Zulu. It also works in reverse, turning a string of code words back into the letters they represent. The alphabet it uses is the International Radiotelephony Spelling Alphabet defined by the International Civil Aviation Organization (ICAO) and adopted by NATO, the ITU, and aviation and maritime services worldwide.

The reason this alphabet exists is that many letters sound almost identical over a noisy phone line or radio channel. B, C, D, E, G, P, T, V, and Z all rhyme, and "M" and "N" are easy to confuse. Spelling a word out as "Mike India Kilo Echo" removes that ambiguity because no two code words sound alike. People reach for it constantly in everyday situations too: reading a confirmation code to a call-centre agent, dictating an email address, confirming a license plate, or spelling a surname that keeps getting misheard.

This translator runs entirely in your browser. Nothing you type is uploaded, logged, or stored on a server, so it is safe for confirmation numbers, account references, or any private text you need to spell out. It supports both the standard number words (Zero through Nine) and the aviation variant that uses Tree, Fower, Fife, and Niner to keep spoken digits unambiguous, and it handles common punctuation. It works offline once the page has loaded and is completely free with no account required.
