Amazon is strictly enforcing their GS1 policy. If you bought cheap barcodes from a third-party reseller, your listings are in imminent danger of suppression. We migrate your ASINs to official GS1 prefixes without losing your reviews.
Years ago, sellers bought cheap barcodes from eBay or SpeedyBarcodes. Today, Amazon cross-references every UPC against the official GS1 database. If your brand name does not match the GS1 company prefix, Amazon delists the product.
Review Retention
Downtime on Active ASINs
Changing a UPC on an active ASIN is technically impossible via the standard Seller Central dashboard. We utilize advanced catalog feeds to force the update.
We guide you through purchasing official GS1 barcodes registered strictly to your Amazon Brand Name.
We generate a new SKU utilizing the new GS1 UPC, and map it directly to the existing ASIN using category-specific flat files.
We transition FBA inventory from the legacy UPC to the new GS1 barcode without losing a single review, ranking position, or day of sales.
Don't do it yourself.
If you try to delete your listing and recreate it with the new UPC, you will permanently lose all of your reviews and sales history.
This process requires surgical precision via Amazon's backend flat file architecture.
