539 Barcode Numbers
In countries where GS1 exists, the ONLY legal way to get to start with these assigned country codes is to join GS1. GS1 is a membership organisation which distributes barcodes by licensing them out for a yearly fee. Companies like Barcode1 Ireland, who sell barcodes for a one off cost, provide numbers typically starting with 06, 07 or 08 (which signifies the barcodes originated in the USA). If you see a company claiming to sell barcodes starting with your local country code (539 in Ireland), they are almost certainly selling made up or illegal numbers.
Many people mistakenly believe that the first few digits of the barcode numbers show the country of origin of the product. However the barcode number says NOTHING accurate about the country of origin of the product. The only thing that these first few digits show is the country of origin of the number. So in reality, products that come from Ireland can have any barcode number on them.
If you want to demonstrate that your product is made in the Ireland, then the best way to do this is to print “Made in Ireland” or similar on the product. This is an advertising claim and must be provable if challenged. (Some manufacturers also print “Made in Ireland” directly above the barcode to help customers).
The myth of the barcode number showing the country of origin of the product is an old myth that has been thoroughly debunked. Please see this Snopes article on the origins of this myth as well as a debunking of it.
