There are several Music burning programs – which one are you using?
What are you entering? Did you try anything else?
If you click on one character in the UPC box then click Ctrl-A everything in the box will be selected. That is a way to make sure anything invisible, like spaces or Ctrl characters get selected.
I'm using Roxio Creator 9 DE, and am specifially in the "edit CD properties for the selected tracks" that are being burned. I've checked again and I only have put 12 numeric characters in the UPC spot. The UPC codes will be part of the CD Text burned. The UPC codes are needed for my original music for sales purposes. And yes, I tried entering a dummy 13 digit number and it took it, but I need 12. UPC codes are universally 12 numeric characters.
