Frequently Asked Questions
Everything you need to know about the NATO phonetic alphabet
What is the NATO phonetic alphabet?
The NATO phonetic alphabet (officially the International Radiotelephony Spelling Alphabet) assigns a code word to each letter (Alpha, Bravo, Charlie...) to communicate clearly over radio or phone, avoiding confusion between similar-sounding letters such as "B" and "P". It is used in aviation, the military, law enforcement and emergency services.
How are numbers and spaces handled?
Digits from 0 to 9 are converted to their English words (Zero, One, Two...). Spaces between words are marked with a " / " separator to keep decoding readable. The reverse conversion (NATO → Text) rebuilds the original text by recognising each code word.
Is the data I enter safe?
Yes. The conversion happens entirely in your browser via JavaScript, without sending anything to external servers. No text is stored or transmitted, ensuring maximum privacy.
What is the NATO phonetic alphabet for?
For spelling letters without ambiguity when the line is poor: saying Bravo instead of B avoids being heard as P or D. It was born for radio and is still used on the phone, in airports and in hospitals.
Does the text I type stay private?
Yes, the conversion runs in the browser with JavaScript and nothing is sent anywhere. No word is stored, so you can spell out confidential codes and references.
