LC 2016 Black/red upc & barcodes

Hey guys, I have two pairs here. Both pairs have subtle variations. For this legit check I'd like to steer away from photographing entire shoes because i'd like to answer a particular question about barcodes on Nike products not just JB I understand that the production dates can be different on pairs. I know that upc numbers match on both boxes and on in the inside tag of all 4 shoes.

The difference I found was not in the upc number but in the bar code on the inside tag of the shoe. If you were to count from right to left the orientation of the bars, They do match each other. 

Notice the barcode changes here. I was under the impression the barcodes were the same. Am I wrong? Thanks guys!

Anyone?

this is a new one by me....have been under the same impression the barcodes should match. I'll check a few of my pairs (and BReds) to see if this pops up for me as well.  

I'm almost positive I noticed different barcodes on 2 of my banned 1s both purchased from retail same size. I'll check asap and let U know.

Thanks guys.
