> Deeper spec here: > https://ref.gs1.org/standards/genspecs/ https://ref.gs1.org/standards/genspecs/ I fear you're mixing it all up :-) Most stuff in supermarkets is labelled only with a EAN or UPC code. While EAN codes carry a country code, it's only the country code of the GS1 country branch which dished out the code range to that company, which does not necessarily mean the product is from there, while UPC codes say even nothing at all about countries. The document you linked to instead is for the full GS1 standard, like it's e.g. often used to track pallets, shipments etc. A GS1 Code 128 code for example can carry all kinds of information, dependent on the Application Identifiers there are in the code - which are explained in the document you linked to. But you will absolutely seldomly see a product tagged with a (long) code like this in a shop. These kind of barcodes get huge soon and are mostly used in shipping or storage. Basically, to REALLY know where a product is from, you'd need a full UPC/EAN database plus do some tracking what kind of company is behind a certain number range. No such official database exists, there are a few inoffical ones though.
