Unique Product Identifiers
Regarding the Google Shopping requirements, manufactured products need to have two out of three unique identifiers.

This is only required for custom goods or products produced before GTINs were introduced.

GTIN
Required for all products with a GTIN assigned by the manufacturer. A GTIN is the numerical version of the bar code and identifies your product and needs to be unique for each product ID. Submit a GTIN as defined in the official GS1 validation guide.
