identifier_exists [identifier_exists]: Definition

Use the 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 [condition] attribute) and it doesn't have assigned product identifiers that meet the requirements below, then submit identifier_exists [identifier_exists] with a value of no [no] or false [false].

Use the following set of rules to provide the correct identifiers for each of your products.

Product identifier requirements
Regardless of category

The gtin [gtin] attribute is required if the product is widely manufactured and has a GTIN.

  Clothing Media Other categories

Required product identifiers based on category

Requires a value for the brand [brand] attribute Requires a value for the gtin [gtin] attribute (for example, ISBN)

Requires a value for the brand [brand] attribute (if there is no brand, provide the manufacturer/supplier name)

If there is no GTIN, provide the mpn [mpn] attribute.

Otherwise If product identifier requirements are not met, then your item's performance may be limited.

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
