What attribute is required in a local product inventory feed?

The correct attribute is store code because it serves as the unique identifier that maps your product inventory to specific physical business locations defined in your Google Business Profile. Without this mandatory field, Google’s systems would be unable to determine which store actually has a particular item in stock, making it impossible to serve Local Inventory Ads or provide accurate "available nearby" information to shoppers. By including the store code alongside product details like price and quantity, you bridge the gap between your digital feed and your brick-and-mortar presence, ensuring that local searchers are directed to the correct storefront to complete their purchase. Would you like me to explain how to ensure your store codes in Merchant Center perfectly match those in your Google Business Profile to avoid feed processing errors?
