International Radio Operator Alphabet

If you work on the phone and must spell out names all the time, use the NATO, FAA and ICAO approved phonetic alphabet:

• Alpha
• Bravo
• Charlie
• Delta
• Echo
• Foxtrot
• Golf
• Hotel
• India
• Juliet
• Kilo
• Lima
• Mike
• November
• Oscar
• Papa
• Quebec
• Romeo
• Sierra
• Tango
• Uniform
• Victor
• Whiskey
• Xray
• Yankee
• Zulu

As a bonus, it works in several languages and it saves the embarrassment of mistranslation when spelling out words: "A as in Ananas"
(Pineapple is a commonly mistranslated word. Aside from the Japanese パイナップル (Literally PA-I-NA-T-PU-RU), almost every other language uses a variation of Ananas, Nanas or sometimes Pina.)
