How to Register GS1 Barcodes for Amazon, eBay, and Shopify

Selling on Amazon or eBay without verified barcodes is like opening a shop without an address your products can’t be found.

Here’s a simple, step-by-step guide to registering GS1 barcodes for your online store.

1. Register with GS1

Visit the GS1 UK website and create an account. Once approved, you’ll receive a GS1 Company Prefix, which forms the foundation of your product codes.

2. Create GTINs for Each Product Variant

Each unique item needs a separate barcode. For example:

  • “Blue T-shirt – Size M” → One GTIN
  • “Blue T-shirt – Size L” → Another GTIN

This ensures every product is traceable and searchable independently.

3. Generate and Download Barcodes

Use the GS1 dashboard to generate barcodes in EAN-13 or UPC format. You can download these for printing or packaging integration.

4. Integrate with Marketplaces

  • Amazon: Go to “Product ID” in your listing and select “GTIN (from GS1).”
  • eBay: Use EAN under item specifics for better visibility.
  • Shopify: Add GTINs to your product listings to sync with Google Shopping feeds.

5. Keep Your Data Updated

When products change (pack size, ingredients, design), assign a new barcode to avoid mismatched listings.
