Identifier exists [identifier_exists]

A custom icon for Merchant Center Classic and Merchant Center Next.

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.

In this article

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 If the product is widely manufactured and has a GTIN, the GTIN [gtin] attribute is required.
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 4 supported values for this attribute:

yes [yes] / true [true]
no [no] / false [false]

Note that the value must be submitted in English.
