I personally think that 'new number' should be accepted as would 'new phone number'.
Number = رقم
Phone number = رقم ہاتف
I agree with GvdMvzik_; over time, it has become understood that we are referring to a phone number when we say this
GvdMvzik i agree but my answer was correct when i write "do you have a new phone number mike" didn't for you being accept?
"Mike" sounds like Malik, but no near as Mike!
How would you say "Is your phone number new, Mike?"
If you want to say "don't you have a new phone number, Mike?", do you put a ليس after the هل?
My answer is correct but it's not accepted
