Changing address before AOR

[ain88]

Hi, I'm moving out to new place before receiving AOR,

I already sent IRCC form but hasn't received any answer yet, not sure how they will figure out which is my documents are mine as I haven't got my file number yet

Any ideas? I heard that, they may return my document if that's not satisfying, to my old home address...in that case..

Please help, I'm not sure

thanks!
