Why Transition to GS1 Barcodes?

Amazon now requires all product listings to use GS1-certified barcodes to verify brand authenticity and ensure data accuracy. Many sellers initially used UPCs that weren’t GS1 certified, leading to compliance errors from Amazon. These errors can result in listing removals and lost sales.

Transitioning to GS1 barcodes ensures your listings remain compliant with Amazon’s policies, protecting your products and reducing the risk of account issues. With Amazon Consultant’s expertise, we guide you through a smooth transition, helping you avoid common pitfalls in the UPC to GS1 change.

Understanding GS1 Barcodes

GS1 barcodes are globally recognized identifiers managed by the nonprofit organization GS1. These barcodes uniquely link products to brands in a standardized and traceable manner, providing the level of traceability Amazon prioritizes to ensure product authenticity.

Unlike generic UPCs, GS1 barcodes connect directly to your brand and company information in the GS1 database. This connection enhances product authenticity, builds customer trust, improves brand visibility, and ensures compliance with Amazon’s requirements.


Using non-GS1 UPCs can lead to significant issues on Amazon, as the platform actively monitors compliance with GS1 standards. Without GS1 certification, your products may face:

  • Listing Removals: Non-compliant UPCs can result in Amazon removing your listings, disrupting sales and visibility.
  • Customer Distrust: Unverified UPCs can raise doubts about product authenticity, damaging your brand’s reputation.
  • Reduced Visibility: Non-compliant listings may lose ranking in Amazon’s search results, decreasing visibility and sales potential.

Amazon Consultant’s UPC to GS1 Code Transition Service ensures your products meet Amazon’s barcode standards, reducing risk and boosting compliance to protect your business.

  • Initial Assessment

We begin by reviewing your current barcodes and Amazon listings to assess compliance and identify any issues.

  • GS1 Barcode Procurement

If your barcodes are not GS1-certified, we assist you in acquiring them through GS1. Our team guides you through the registration process and helps secure the necessary certified codes.

  • Listing Update and Transition

Next, we update your listings by replacing the UPC barcode with the newly acquired GS1 barcode. We ensure a smooth transition to minimize downtime, keeping your listings active and inventory levels intact.

  • Compliance Confirmation

After the update, we verify the barcode transition and monitor your listings to ensure compliance, confirming Amazon’s acceptance of the GS1 barcodes.

With our streamlined process, we help you seamlessly transition to GS1, ensuring compliance and minimizing disruptions to your business.
