Assigning EPREL numbers to products

To display the correct energy badge, show the official energy label, and enable PDF download of the product information sheet, each energy-efficient product in your catalog must have its EPREL number assigned.

  1. Go to Products in your Shopify admin.

  2. Open the product you want to assign an EPREL number to. Scroll to the Product metafields section and locate the EPREL Registration Number field.

  3. Enter a valid EPREL number and click Save.

Once saved, the storefront will display the official energy badge for that product. Clicking on the energy badge will open the pop-up with full energy label, and the product information sheet link will download a localized product fiche in PDF format.

Once saved, the storefront will display the official energy badge for that product. Clicking the badge opens a pop-up with the full energy label, while the product information sheet link downloads the localized fiche in PDF format.
