What is the difference between a GTIN and an MPN number, and which do you need for Google Shopping listings?
A **GTIN (Global Trade Item Number)** is your product barcode, typically obtained from GS1. It usually appears as a GTIN-13, which is also known as an EAN. This is the primary identifier needed for Google Shopping listings.
An **MPN (Manufacturer Part Number)** is a separate identifier assigned by the manufacturer, but it is not typically required for Google Shopping in the same way a GTIN is.
Members recommend: - Source your GTIN through **GS1** — the standard route for obtaining official barcodes that work with Google Shopping - If you're struggling with the process, reach out to experienced members in the community who have offered to walk others through the steps
For grouped product listings (e.g. multiple flavours from a single SKU), ensure each variant has its own GTIN.
