Identifier exists [identifier_exists]

Use the identifier exists [identifier_exists] attribute to indicate that unique product identifiers (UPIs) aren’t available for your product. Unique product identifiers are submitted using the GTIN [gtin], MPN [mpn], and brand[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 using the condition [condition] attribute) and it doesn’t have assigned product identifiers that meet the requirements below, you should submit the identifier exists [identifier_exists] attribute with a value of no [no] or false [false]. (Note this value must be submitted in English).

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.

 

Apparel

Required product identifiers based on category

Requires a value for the brand [brand] attribute

Otherwise

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

Products that might not have unique product identifiers include:

  • Custom goods or one-of-a-kind products, 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 products

There are four supported values for this attribute:

yes [yes] / true [true]
