How do you convert text to the NATO phonetic alphabet?

Each letter maps to its NATO code word (A→Alfa, B→Bravo…) and numbers map to spoken words, with a space shown as " / ". The code words were designed to sound distinct over noisy lines, which is why aviation, the military and customer support use them. For example, "Toolzio 24" becomes "Tango Oscar Oscar Lima Zulu India Oscar / Two Four".

Understanding your result

The alphabet was designed so that each code word sounds distinct from the others, even over a noisy line, which is why it is used worldwide in aviation, the military and customer support.

Formula and method

Each letter maps to its NATO code word (A→Alfa, B→Bravo…). Numbers map to spoken words, with an optional aviation set (Wun, Too, Tree, Fower, Fife, Niner). A space between words is shown as “ / ”.

Worked example

“Toolzio 24” becomes “Tango Oscar Oscar Lima Zulu India Oscar / Two Four”.

Frequently asked questions

Why is it spelled “Alfa” and “Juliett”?

The official spellings avoid mispronunciation by speakers of different languages, so “Alfa” and “Juliett” are intentional.

What is the aviation number option?

Aviation radio uses slightly altered number words such as “Tree” for three and “Niner” for nine so they are not confused with similar-sounding words.
