If we purchase bar codes from third party but the bar codes will be registered to us under our name and company will they work on Amazon if we are a branded company?
the bar codes and product info will be in the the UPC product database
Yes they will work. I use them too. The downside is you don't own them so they could be taken away from you at some point. I wouldn't use them for anything that you manufacture for that reason but for selling you can.
