NATO Phonetic Alphabet
The NATO (ICAO) phonetic alphabet from Alfa to Zulu, plus the standard pronunciations for the digits 0 to 9, used to spell out letters clearly over radio and phone.
The NATO phonetic alphabet (the ICAO radiotelephony spelling alphabet) gives each letter a
standard word so it is understood clearly over radio and phone. Note the official spellings
Alfa and Juliett. Click any word to copy it.

Frequently asked questions
Why is a phonetic alphabet used?
Many letters sound alike over a phone or radio, like B and P or M and N. A standard word for each letter removes the guesswork so the listener gets it right the first time.
Is it official, and is it the same everywhere?
Yes. It is the International Civil Aviation Organization (ICAO) alphabet, adopted by NATO and used worldwide in aviation, maritime, and telecom.
How are the numbers pronounced?
Digits have their own standard pronunciations to avoid confusion, such as NIN-er for 9 and FIFE for 5, with TREE for 3 and ZERO or OH for 0.
