Saying your email address over the phone

The author references "I... A... S... India, Alpha, Sierra", and I immediately recognized those as words from the NATO Phonetic Alphabet [1].

I have found it to be a wonderful tool when I need to spell out loud. Now that I have the alphabet's acrophonic words memorized, I no longer fumble to create words on the fly that match the target letter. Plus, there is no second-guessing by the listener, since the words in the alphabet were selected to reduce ambiguity.
