Grow eBay sales & ensure product authenticity with accurate GTINs.

GTINs (Global Trade Items Numbers) created by GS1 are the numbers you see beneath barcodes on items sold around the world. eBay is now using these same numbers as product identifiers enabling sellers to correctly classify products, improve search rankings and reassure buyers the products are genuine and authentic.

Our partnership with GS1 helps you to manage your GTIN data.

  • The Optiseller eBay Store Performance Dashboard checks your listings against the GS1 database
  • You’ll be able to quickly see how many listings have GTINs and how many are valid
  • To help correct errors you can download a file with the ID’s of all affected listings

Don’t miss out on potential sales. Make sure your product data is accurate, subscribe today.
