Seller update UPC code requirement, do you really need them?

[fenris_st_germain]

The new requirements now demand a UPC code on new items in a bunch of categories
The only exception seemed to be "custom made" or totally unbranded things. 
Are they really expecting people to run out and buy batches of UPC codes just to make them happy if they want something listed with a brand name of any kind?

I ALWAYS enter the one that says something like not applicable. Can't remember the exact wording but i have never had a problem doing that. New used or whatever.
