Element g:identifier_exists#

Basic information#

The g:identifier_exists element tells Google that the product has no unique identifiers — meaning it has no g:gtin (EAN/ISBN/UPC), no g:mpn (Manufacturer Part Number), and no g:brand (manufacturer brand).

The permitted values are false or no.

If the product has at least one of the identifiers listed above, do not include g:identifier_exists in the feed.

• g:identifier_exists element specification in Google Merchant Center Help

Elements whose absence requires the use of g:identifier_exists:

• g:gtin — numeric product code (EAN, ISBN, UPC…)
• g:mpn — Manufacturer Part Number
• g:brand — product brand or manufacturer

Frequently asked questions#

• When do I need to use g:identifier_exists?
  • When the product has none of these three identifiers: g:gtin, g:mpn, or g:brand. This typically applies to custom products or made-to-order items where the manufacturer also sells under their own private label without assigned codes.
  • If the product has at least one identifier, do not use g:identifier_exists.
• What value should I enter in g:identifier_exists?
  • Enter the value false or no. Both values are accepted by Google as equivalent.
• How do I populate the g:identifier_exists element in Mergado?
  • First, on the Products page, create a query for products that have no identifiers. On the Elements page, verify that the g:identifier_exists element exists in the feed. If it does not, create it manually. Then create a Rewrite rule that sets the value false for the selected products.
• What happens if I do not fill in g:identifier_exists and products have no identifiers?
  • Google may reject such products or display them with limited visibility in Google Shopping. Correctly filling in this element prevents errors in Google Merchant Center.
