Barcode used for magazine

I feel using a barcode on my magazine will give it a sense of realisim
in terms of that it shows that it is a product which can be sold in newsagents
and supermarkets.

I feel though something needs to be removed from the front cover of my piece to
fit in the barcode, due to fact there seems to be to much unesscary text on the front
page for example the advertisement on a trip to Las vegas, this space could be used  for the barcode
on the front cover of my magazine.
