I would wish from Arduino Team to have a better labeling of the Packages. For sorting it out an EAN, Barcode would not take much place on the Package. New Staff have everytime the Problem to sort the right Product for the Order.
Maybe they intend for you to slap your own barcode sticker on it? Also, I am not sure whether getting an assigned EAN would cost money or not (it appears that the codes have something to do with the formerly named UCC - which, in my experience with dealing with them in regards to EDI - nothing is ever "free", and is in general fairly expensive for what you get); maybe they don't do it to save money?
Save Money?? You mean if they add any internal Custom Product specified Barcode Number with a Barcode on the Package Layout will save Money??
Sorry but this is not the way to save Money. The Reseller have to print for each Product Type a Barcode Label which cost Money. Than one of Staff must stick it which takes time and cant do the own Job. This cost again Money!
The Packages have a Label with unique Number but this is not a Product Number.
