Notice of approval 没收到， 这可怎麽办?

网上查的， NIW I140 批准了, 但因为搬家的问题， 正式通知没收到， 可以不附加通知只附加收据递交485 吗? 多谢回答.

I recently learn from CIS website that my I140 NIW has been
approved. But as I moved and changed the address, I didn't receive the
official approval letter. Do you think if I can proceed to adjust my
status of I485 without obtaining the official notice of action, or should
I call them and try to get the letter first?(I still don't know what to do
to get the letter).
Thank you very much.
