regex - Regular Expression Notepad increment numbers in every line

Question

I've to add numbers incrementally in the beginning of every line using Notepad++. It is the not the very beginning. But, like

  when ID = '1' then data
  when ID = '2' then data
  when ID = '3' then data
  .
  .
  .

  when ID = '700' then

Is there any way i can increment these numbers by replacing with any expression or is there any inbuilt-notepad functions to do so.

Thanks
