- In India generally when there are two 9s and two 8s we call and convey the numbers as double 9 and double 8 respectively.
- But in US and other countries they don't use double 9 and double 8 while conveying the information.
- They instead say nine nine and eight eight.
- So they don't understand double 9 and double 8 while we conveying the information when there are numbers.
- So there is big problem in communication.
- Hence double 9 and double 8 are not recommended for clear communication.
