Job ID: 34608634

Budget: $10 – $30 USD

Hello,

I sell mobile phone cases and tempered glasses on my e-commerce. I recently created a google merchant account, in order to be able to create a first shopping campaign, I must configure all of my products with a GTIN, UPC, EAN, JAN or ISBN identifier.

I receive my products in bulk from China, so there is no barcode.

How to configure these products in such a case?
