Marketplaces rely on Verified by GS1 and GS1 data to check GTINs

Every day, more than 20 leading marketplaces are checking millions of GTINs provided by sellers with Verified by GS1.
As the fastest-growing retailers, marketplaces face the challenge of managing an ever-increasing number of products. Many of them require Global Trade Item Numbers (GTINs) to maintain the quality of their data: ensuring catalogues are organised and free from errors and duplications. This helps to improve the consumer shopping experience, leading to more sales1 for everyone!
The Verified by GS1 service provides access to a global database of GTIN numbers—unique identifiers for products. With Verified by GS1, marketplaces can clean up their catalogues by removing incorrect numbers, grouping sellers under the same product page and comparing product data with external sources.
