identifier_exists: Definition
Use the
identifier_exists attribute to indicate that unique product identifiers aren’t available for your product. Unique product identifiers include gtin, mpn, and brand.
When to use
Required only for new products that don’t have gtin and brand or mpn and brand.
If your product is new (which you submit through the condition attribute) and it doesn’t have a gtin and brand or mpn and brand then submit identifier_exists with a value of no.
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
