Will my bar code work with Amazon, eBay, Google, Etsy etc.?
works with Amazon
Yes, GTIN’s (UPC’s/EAN’s) are what the entire world uses in their P.O.S. systems. There is no such thing as an "amazon barcode" it's the other way around, Amazon uses what the entire world uses: barcodes's from GS1, the way it's been done since the early 70's.
All of our GTIN inventory comes from GS1-USA, specifically before 2002. This is how you can legally own them vs renting them. Some stores may have custom, arbitrary rules and you would need to check with the store first to make sure they follow the standards that GS1 operates on.
A note on Amazon:
We, as well as many thousands of Amazon sellers have clarified with Amazon’s seller support that their GTIN requirements have not changed and that sellers (you) are allowed to own your own GTIN's as long as they are legal.
We believe their seller-facing statements regarding bar codes have been to threaten those less-than-honest sellers & scammers whom try & succeed in defrauding Amazon’s open (trust based) system by guessing, making-up or stealing other’s GTIN’s intentionally. *Using a company's GTIN without express permission is illegal. This does not apply if a seller is trying to create a listing based on an item that already exists in the market, aka "piggy backing" , this piggy-backing system was created & promoted by Amazon and while it's a bit of a grey area it is Amazon's choice to set their POS system up that way.
