identifier_exists attribute to indicate that unique product identifiers (UPIs) aren't available for your product. Unique product identifiers are submitted using the gtin, mpn and brand attributes.
When to use
Use for products that don't have a GTIN, MPN or brand.
If your product is new (which you submit through the condition attribute) and it doesn't have a value submitted for the gtin attribute, or both the mpn and brand attributes, then submit identifier_exists with a value of no or false.
Products that might not have unique product identifiers include:
- Custom goods or one-of-a-kind items, like custom T-shirts, art or handmade goods
- Products produced before GTINs were introduced, like vintage products, antiques, books published before 1970 and other special items
