The DataHub is a tool included with your GS1 membership and uses your GS1 Company Prefix (the number that uniquely identifies your company) to create GTINs to uniquely identify your products. It is important to note that the DataHub does not actually publish or promote products to trading partners, but is a repository for storing GTIN assignments and product data. Also, basic access to the DataHub is limited and does not allow members to download GTINs and Case Barcodes (GTIN-14) without an upgraded membership ($4500). GS1 US offers training webinars for the DataHub for $79. Companies who use the GS1 Barcode Service are not required to purchase the webinar since UPC management and Data Hub uploads are included. Please call us at 800-662-0701 x250 or visit GS1 Barcode Service.
