Change the product unique identifier

Learn how we generate the unique product identifier for your products, and how you can change it.


All the products in your catalog have a unique product identifier. We use this unique product identifier to tell the difference between products and to link products to any associated order data.

By default, product recommendations uniquely identify your products by combining two fields: the product name and the SKU. In most cases, this is a reliable default configuration, as it makes sure product recommendations work even if you don't have a unique SKU for every product.

Changing the unique product identifier for products in a catalog

To change the unique product identifier for products in a catalog:

  1. Go to Ecommerce > All stores > Catalogs.
  2. Select Properties for the catalog you want to edit.
  3. From the side panel, under the heading Product recommendation settings, expand the Unique product identifier drop-down menu, then choose the configuration option you want to use

    To learn more, check out Understand the configuration options.

  4. Select APPLY.

Are you sure?

If you are unsure whether changing this configuration will give you the results you want, please contact our support team for advice. 

Understand the configuration options

The field options available show what is typically available in both your catalog and order data, so we can reliably link both these data sets together.

Unique product identifier Description
Name + SKU (default) Best for most cases. Flexible with imperfect product data, such as missing or duplicate SKUs.
SKU Works if all products have a unique SKU. This setting is more restrictive but does allow for flexibility, such as changing product names and maintaining their link to their orders. 
Name If not Sku is present and product names are the only possible identifier.

Refresh your product recommendations

After you change your unique product identifier, you must refresh your product recommendations to reflect the change.
