The Ultimate Guide to Barcode Registration for eCommerce Sellers
Every product you see on Amazon, eBay, or Shopify has a barcode a tiny detail that makes global commerce possible.
If you’re selling online, understanding barcode registration isn’t optional it’s essential forproduct authenticity, listing approval, and marketplace compliance.
What Is a Barcode and Why Does It Matter?
A barcode is a unique product identifier (like a digital fingerprint). It helps retailers and marketplaces track, verify, and manage products globally.
Common types include:
- UPC (Universal Product Code) – used mainly in the US.
- EAN (European Article Number) – standard in the UK and EU.
- GTIN (Global Trade Item Number) – recognised globally.
Without a valid GS1 barcode, your listings can be removed or flagged as “unverified.”
The Role of GS1 in Barcode Registration
GS1 is the only global authority that issues authentic barcodes. Marketplaces like Amazon, eBay, and Google Shopping require sellers to use GS1-registered codes to ensure credibility and traceability.
Steps to Register a Barcode for Your Product
1. Join GS1 UK (or your country’s GS1 body).
2. Receive your GS1 Company Prefix – this identifies your brand.
3. Assign unique GTINs to each product variation (colour, size, pack)..
4. Generate barcodes (in EAN-13 or UPC format).
5. Print or integrate them on your product packaging and listings.
Why Cheap Barcodes Can Harm Your Business
Many sellers buy “cheap barcodes” online, but these often come from unauthorised sources. They can cause:
- Amazon listing rejections.
- Duplicate product data.
- Loss of brand trust.
Always register your barcodes through GS1-certified partners for lifetime validity.
