: GTIN number Google Shopping I'm new to Google Shopping. We have been required to use GTIN number for our products. I understand this GTIN number has to be unique. But is it enough to be unique

@Radia820

Each complete GTIN is unique for the whole world.

A GTIN is a
Global Trade Item Number.
There are several types of GTIN,
including


Universal Product Code (UPC), common in North America
International Article Number (IAN), common in Europe and Japan
International Standard Book Number (ISBN)
etc.


Typically a particular type of GTIN has 4 parts,


a "group indicator" (typically indicating the country a national registration agency is in),
a "manufacturer code" (typically a number that the business buys from a national registration agency for a small fee; the agency makes sure each business in that country gets a unique number.),
a "product code" (the manufacturer is responsible for making sure each of its kinds of products gets a different product code), and
a checksum.


This way each kind of product can be assigned a number unique across the whole world.

Some manufacturers stamp their product with not only a GTIN for that model of product, but also a serial number counting how many of that model has been manufactured.

Google says


"Some products don’t have a GTIN assigned, and so you don’t need to
submit one. However, if the product does have a GTIN assigned and you
don’t submit it, then the product could be disapproved."
-- "Products without a GTIN"

Oops! I miss read it.

Based on my past setup with Google, gtin can be left blank if you don't have.

mpn can be any unique number which identifies your products uniquely.
