Today at work we were discussing the phonetic alphabet to use when spelling things out over the phone. The one I’m used to is (I’ve learned) NATO standard from 1954:
Alpha, Bravo, Charlie, Delta, Echo, Foxtrot, Golf, Hotel, India, Juliet, Kilo, Lima, Mike, November, Oscar, Papa, Quebec, Romeo, Sierra, Tango, Uniform, Victor, Whiskey, X-ray, Yankee, Zulu
But there are others used by police, military, etc. The linked article gives some interesting history. You may prefer, for example, to use RAF 1942-43:
Apple Beer Charlie Dog Edward Freddy George Harry Ink
Jug/Johnny King Love Mother Nuts Orange Peter Queen
Roger/Robert Suga Tommy Uncle Vic William X-ray Yoke/Yorker
Zebra
…or Esperanto:
