Overview

Error 100458 is a listing error that Amazon sellers may encounter when attempting to create or update product listings using a GTIN (Global Trade Item Number) such as a UPC, EAN, or ISBN. When triggered, the listing request is blocked entirely, preventing the product from going live. Understanding the root causes and resolution steps is essential for sellers who need to get their products listed quickly and avoid disruptions to their catalog.

Key Points / What Sellers Need to Know

• Listing requests are fully blocked — When error 100458 fires, Amazon will not process the listing at all until the underlying issue is resolved.
• GTIN-related issue — The error is directly tied to the product identifier (UPC, EAN, or ISBN) being submitted with the listing.
• Multiple possible causes — The error can stem from blocked GTINs, duplicate listings, conflicting product data, or potential policy violations.
• Documentation may be required — Resolution often involves providing proof of GTIN ownership, invoices, and brand authorization.
• Contact Seller Support if needed — Amazon recommends reaching out to Seller Support if the issue persists after following the standard resolution steps.

Why This Error Occurs

There are several reasons Amazon may trigger error 100458 on a listing attempt. The most common cause is that the specific GTIN (whether it is a UPC, EAN, or ISBN) has been blocked by Amazon's systems. This can happen when Amazon detects irregularities associated with that identifier. Another frequent cause is the existence of duplicate listings or conflicting product information already tied to the same GTIN in Amazon's catalog. If two or more sellers have submitted different product details under the same barcode, Amazon may block further listing attempts to prevent catalog corruption. Finally, the GTIN itself may have been flagged for potential violations or incorrect usage, which can occur when barcodes are resold, recycled, or applied to products that do not match the original registration.

How to Resolve Error 100458

Sellers who encounter this error should take a systematic approach to resolution. The first step is to verify that the GTIN being used is valid, authentic, and accurately corresponds to the exact product being listed. Sellers should confirm the barcode was obtained from a legitimate source such as GS1, the official global standards organization for GTINs. Next, sellers should prepare and submit proof of GTIN ownership along with product authenticity documentation. This typically includes manufacturer or supplier invoices that clearly show the product and its associated barcode. If the seller is listing under a brand they do not own, brand authorization letters may also be required to demonstrate permission to use that GTIN. Once this documentation is gathered, sellers can submit it through Seller Central or provide it directly to Seller Support when opening a case about the error.
