  • All product data is independently audited and verified to ensure accuracy and quality
  • Suppliers share this product data and images with retailers in a consistent format

productDNA owned and governed by the retail industry, and is managed by GS1 UK on their behalf.

productDNA has been built for the retail industry. It was specified by a group of leading grocery retailers and suppliers who shared the common need for high quality data and a standardised way of listing their products.

At launch the service will cover the specific needs of the grocery sector. In effect this means all product categories within a supermarket with the exception of GM and clothing. GS1 UK is working with other sectors within retail to understand their specific needs and to agree the product attributes required to describe their products.

  • productDNA offers retailers an easy way to access high quality, independently verified product data they can trust
  • Retailers can provide a better experience for shoppers by providing accurate and consistent product information and images through every channel, in-store and online

productDNA is owned and governed by the retail industry through the GS1 UK Retail Grocery Advisory Board, which is made up of 17 leading UK retailers and brands. The Board has requested that GS1 UK manages productDNA on their behalf for the benefit of the retail industry.

GS1 UK is a community of over 38,000 members and is one of 112 independent, not-for-profit GS1 organisations operating across 150 countries worldwide. GS1 UK helps industries such as retail and healthcare transform the way they work and serve their customers through the provision of open, global standards.

All retailers and suppliers can register their interest today.  

As retailers implement productDNA they will communicate directly with their suppliers, inviting them to provide their product data via the productDNA service.

productDNA enables multiple images to be stored against each product. These can be uploaded by suppliers and accessed by authorised retailers.

My Numberbank is a service provided free of charge to all GS1 UK members. It allows members to allocate unique product identifiers called GTINS (Global Trade Item Numbers) to all their products. Seven product attributes are required for each GTIN (product name, main brand, sub-brand, description, web link to the product, MPN (Manufacturer’s Part Number) and SKU (Stock Keeping Unit)).

My Numberbank is increasingly used by online retailers, online marketplaces and healthcare catalogue providers to check the validity of the GTIN used in their product catalogues.

productDNA defines and manages far more product data. At launch there will be 150 data attributes for products across the grocery sector, including product data such as dimensions, weight and volume, as well as ingredients, nutritional values and allergen information. Additionally, productDNA also allows suppliers and retailers to share this product data between them in a controlled manner, respecting commercial agreements between retailer and supplier.

TrueSource is a GDSN-certified data pool service from GS1 UK. It has been used for many years, mainly in the foodservice industry and for suppliers to some international retailers. Subscribers to TrueSource will be able to publish their GDSN data to productDNA where it can be amended in line with the UK grocery sector data model used by productDNA.
