Understanding the NATO Phonetic Alphabet
What is the NATO Phonetic Alphabet?
The NATO phonetic alphabet (officially the ICAO spelling alphabet) is a set of code words assigned to each letter of the Latin alphabet. Each word was chosen to be phonetically distinct from all others, minimising confusion when spelling out letters over radio, telephone, or noisy environments. The current standard — Alpha, Bravo, Charlie, Delta… — was adopted by the International Civil Aviation Organization (ICAO) in 1956 and is used by NATO, aviation, military, law enforcement, and emergency services worldwide. Our NATO phonetic alphabet converter encodes any text to these standard words and decodes them back instantly in your browser.

- Digits (0–9): Digits are converted to their spoken names — Zero, One, Two… Nine. This matches the standard used in aviation and military communication.
- Common Punctuation: Common symbols like Stop (.), Comma (,), Query (?), At (@), Hash (#), and Slash (/) are converted to their spoken names for complete text coverage.
- Show Original Char Mode:Enable the "Show original char" toggle to display the original character alongside each NATO word — for example,
Alpha(A). Useful for learning and verification.
