When I want to express the count of something, can I say "xxx number" instead of "the number of xxx"?

For example:

"Location number" to mean the number of locations.

 

"Apple number" to mean the number of apples.

If putting the word "number" after the counted thing like this applies conditionally, what's the conditions?

Thank you for your help.
