How to set identifier_exists to no for products without GTIN

A rule: if gtin and mpn are empty, set identifier_exists to no. Merchant Center stops flagging products that truly have no barcode, such as handmade items.

Open in the app →About this feature

Merchant Center expects a GTIN (barcode) for branded products. Products that have no barcode at all should say so with identifier_exists = no; otherwise they get “Missing value [gtin]” warnings and limited reach.

Open the data source, go to Rules and create a new rule - for example “No identifiers”.
Under Conditions pick gtin Is empty, add a second condition with “and”: mpn Is empty.
Under then pick the field identifier_exists (if your catalog does not have it, create it with New Column), choose Combine or set value and type no.
Check Changes preview, then Save Rule, and map identifier_exists in the Google export if it is not mapped yet.

Example

Product with gtin empty and mpn empty → identifier_exists: no
Product with a GTIN → unchanged, the rule does not touch it

Use it only for products that truly have no GTIN. Setting “no” on a branded product that has one hides a real problem and can get the product disapproved.
