- In India commonly repeated digits speaks like double or triple.
- But in America, however, where the telephone numbers take the form (555)555-5555, you would be unlikely to use "double or triple".
- (555)555-5500 would likely be "five-five-five, five-five-five, fifty five hundred" (or even five-five-oh-oh) and (555)555-5000 would most likely be "five-five-five, five-five-five, five thousand".
- The American Automobile Association is AAA (triple A) and AA batteries are "double A batteries", but AA for Alcoholic anonymous is pronounced "a a" and "BB gun" is pronounced as "bee bee gun".
