In the complex world of e-commerce, few decisions are as critical, and often as confusing, as choosing your barcode source. For many sellers, the terms "GS1" and "reseller barcodes" are thrown around, leaving them wondering: What's the real difference? Which one do I need? And will Amazon reject my product if I choose wrong?
In the fast-paced world of 2026 retail, the "single-platform seller" is becoming a thing of the past. To stay competitive, modern brands are adopting an omnichannel approach—launching on Amazon today, scaling to Walmart.com tomorrow, and capturing viral growth on TikTok Shop by the weekend.
Are you an Amazon seller looking to launch new products, but feeling overwhelmed by barcode requirements and the cost of GS1 subscriptions? You're not alone. The landscape of product identification on Amazon can seem complex, especially with evolving policies and the common misconception that GS1 is your only option.
