Do these companies require a UPC code to RMA?

[Newjy]

I have recently bought a new computer, but half of the products had a mail-in rebate. Little did I know, if you were to mail your UPC code for the rebate, the warranty would disable for some companies.

These are the companies I bought from:
NZXT (Case)
OCZ (PSU)
XFX (GPU)
Corsair (Memory)
AMD (CPU)
ASRock (Motherboard)
Sony (DVD Drive)
HITACHI (HDD)
ASUS (Monitor)

If any of the companies in that list require a UPC code to RMA, can you please list them? Thanks!
