Please read this page carefully BEFORE purchasing barcodes <\/strong><\/span><\/h4>\n

for use exclusively on Amazon.<\/strong><\/span><\/h4>\n

We try to keep this information up-to-date, but since\u00a0Amazon\u2019s policies concerning barcodes continue to change and they are not the same across the different Amazon sites, it is best to check directly with them to be absolutely certain of the most current requirements.<\/span><\/p>\n

Amazon requires the use of barcode numbers (13 digit EAN or 12 digit UPC) as unique product identifiers. They also assign their own unique identification numbers called<\/span>\u00a0<\/span>ASIN<\/strong>\u00a0<\/span>(Amazon Standard Identification Numbers).<\/span><\/p>\n

In the past anyone could list a product using any barcode number, as long as that barcode number wasn\u2019t already being used for another product on Amazon. This caused problems to legitimate sellers, who could find their legitimate numbers stolen and used by someone else on Amazon.<\/p>\n

Searching\u00a0<\/span>legacy barcode numbers<\/span><\/h3>\n

In late 2016, an Amazon Executive joined the board of governors of GS1 and Amazon began tightening their policies in order to clean up the Amazon database. Unfortunately there are still legacy barcode numbers in use on Amazon that conflict with the numbers we own and sell. To avoid problems with this, we have been implementing increasingly thorough searches of the Amazon databases to find these fraudulent legacy numbers<\/strong>. We have used the Amazon APIs to search currently listed products, but this method does not allow for deep enough search of Amazon databases and has had limited success. We sought advice from Amazon support, but they were unable to assist. In response our tech-gurus developed sophisticated search software that goes far beyond traditional Amazon search options. We now operate a dedicated server that is searching Amazon’s databases for all numbers (including unlisted ones) before we sell them. If we find any of these historic fraudulent listings using our numbers, we delete these numbers and do not sell them<\/strong>. Our proprietary software is much more effective than the Amazon APIs, and searches much deeper than any other barcode seller.\u00a0<\/span><\/p>\n
