The NATO phonetic alphabet assigns a distinct word to each letter so that spelling stays clear over a radio, a phone line, or any connection where individual letters can be misheard. "B" and "D" sound alike on a bad line — "Bravo" and "Delta" don't.

NATO alphabet converter: spell any word
Type a name, a postcode, or a booking reference to see it spelled out in NATO words, ready to read over the phone or radio. Numbers use the standard radio words, including "Niner" for 9.
Why it exists
The system was standardized by the International Civil Aviation Organization and adopted by NATO in the 1950s, after earlier versions used in aviation and the military proved confusing across accents and languages. Each word was chosen to be easy to pronounce and hard to confuse with another word on the list, even over a noisy channel.
Who actually uses it
Pilots and air traffic control, military and emergency radio operators, ships at sea, and call centers reading back confirmation codes, order numbers, or license plates all rely on it — the same kind of mixed letter-and-number codes covered in our letter and number generator guide. Outside of those fields, it's also a handy way to spell your name or email address clearly over the phone.
How to practice
The fastest way to build recall is repetition against a random prompt rather than reading the list top to bottom in order — reading it in order teaches the sequence, not the letter-to-word mapping itself. Our random letter generator has a dedicated Phonetic mode: switch to it, press Generate, and it returns a random letter plus its call sign, with an option to hear it spoken aloud.
Common mix-ups worth double-checking
A few pairs trip people up: Mike (M) versus November (N), Sierra (S) versus X-ray (X), and Juliett (spelled with two Ts, not one) versus Charlie. Quebec (Q) is also often misremembered as "Quebeck." Worth noting: Zulu (Z) and X-ray (X) are also among the rarest starting letters in English — see our letter frequency guide for the full breakdown.
