Amazon UPC, GTIN & Product ID How-To Guides
This is the Amazon product ID section of the Goat Consulting blog, where we cover how UPCs, GTINs, and Amazon's product identification system actually work from a seller's point of view. You'll find practitioner-written guides on the differences between UPC, GTIN, and EAN, Amazon error codes, what GS1 is, how to apply for a product ID exemption, and how GTIN hijacking and commingling work. Every post is written by a member of our team who has set up and cleaned up product catalogs for brands, so you get both the rule and the real-world workaround.
Most sellers land here trying to diagnose a listing error or figure out what kind of barcode they need, so the posts below are a working reference when Amazon throws a product ID problem at you. If you'd rather have the Goat Consulting team reclaim a GTIN, fix an error code, or clean up your catalog's product IDs for you reach out to us.
