# How to set "identifier exist" as No in Nabu Google Shopping Feed app?

## Identifier exists (Yes / No) tells Google whether the product has manufacturer-assigned identifiers such as **GTIN** (UPC/EAN) or **MPN**

This short article explains what the setting does, where to find it in Nabu Google Shopping Feed app, when to choose Yes or No. 

### Where to find it in Nabu Google Shopping Feed? 

1. Open a product in Nabu Google Shopping Feed app. 
2. In the product editor, go to Recommended Details → Shopify’s Product identifiers.
3. You will see fields for GTIN, MPN and the Identifier Exists option with Yes / No radio buttons. 
4. Select the required option and click save.

### What “Identifier exists” actually does? 
* Yes = You tell Google this product has manufacturer identifiers. Google will expect (and use) GTIN/MPN/brand values for matching, classification, and product accuracy.
* No = You tell Google this product does not have manufacturer identifiers. Google will treat the product as lacking manufacturer IDs and will not require GTIN/MPN/brand for matching the same way it would for a product with identifiers.

This is important because Google uses these identifiers to:

1. Match your product to the correct listing in Google’s catalog. 
2. Improve product classification and search relevance. 
3. Enforce requirements in categories where identifiers are required.

### When to choose "Yes"

Choose Yes when the product has manufacturer-assigned identifiers that you can provide:
1. A valid GTIN (UPC/EAN/ISBN) printed on the product or packaging.
2. A manufacturer MPN and brand.
3. Branded, new retail products supplied by a manufacturer or authorized distributor.

Why: If identifiers exist, providing them and setting Identifier exists = Yes helps Google correctly identify your product and improves visibility.

### When to choose "No"

Choose No only when the product truly does not have manufacturer identifiers:

1. Handmade or custom items where the maker did not use GTIN/MPN.
2. Vintage / used items with no manufacturer barcode.
3. Merchant-created bundles (a group of products sold together that do not have a single manufacturer GTIN).
4. Products that are refurbished or resold without original manufacturer identifiers and the identifiers cannot be supplied.

Why: Marking No prevents Google from expecting manufacturer IDs and can reduce disapprovals for items that legitimately lack them.
