Overview

Sellers who encounter Amazon error 18623 are being blocked from listing a product because the brand or category requires explicit permission. The restriction appears at the moment a new ASIN is created or an existing one is edited, and it signals that the seller’s account has not yet been cleared by the brand owner or Amazon’s brand‑gating system. Resolving the error is essential for anyone who wants to add high‑margin, brand‑protected items to their inventory.

Key Points

• Brand‑owner approval is mandatory — Brands that enroll in Amazon’s Brand Registry can designate which third‑party sellers are allowed to list their items, and any attempt to list without that designation triggers error 18623.
• Category‑level gating compounds the issue — Certain categories such as “Health & Personal Care” or “Jewelry” are fully gated, meaning every brand inside the category demands a separate approval regardless of the brand’s individual policy.
• Documentation quality determines success — Amazon typically asks for recent invoices from an authorized distributor, and invoices that omit the brand name, product SKU, or seller’s business details are rejected in up to 70 % of cases.
• Seller‑account health influences the decision — Accounts with a high order‑defect rate or recent policy violations are less likely to receive brand‑gating clearance, even when the paperwork is flawless.
• Approval must be confirmed before relisting — Once Amazon sends a confirmation email, the seller should wait at least 24 hours before attempting to create the listing; premature attempts will continue to generate the same error.
• Multiple brands may require separate applications — A wholesale operation that sources from three different manufacturers will need to submit three distinct approval requests, each with its own set of invoices and brand‑owner contacts.

How to Get Approved for Brand‑Gated Products

1. Locate the brand‑gating request form in Seller Central — Navigate to the “Add a Product” page, click the “Brand Approval” link, and select the specific brand; for example, a seller wanting to list a new line of “EcoPure” water filters will see a “Request Authorization” button next to the brand name.
