FBA Inbound in 2026: Even with a GS1 Barcode, You Can't Ship Without THIS!

TL;DR As of now, Brand Registry will become mandatory if you want to use manufacturer barcodes (UPC/EAN) for Amazon FBA (Fulfillment By Amazon) inbound shipments. Even if you have a GS1 barcode, FBA inbound shipments may be rejected if you are not brand registered, so be sure to verify this.

Amazon Strengthens GTIN and Brand Registry Policies

Amazon is continuously strengthening its GTIN (Global Trade Item Number) policy to ensure listing accuracy and brand protection. There have been many significant policy changes recently for Korean sellers. The most important point to note is that as of now, Brand Registry enrollment is mandatory if you want to use manufacturer UPC (Universal Product Code) barcodes for FBA shipments.

This means that simply having a valid GTIN issued by GS1 may no longer be enough for FBA inbound. Brands without a USPTO (United States Patent and Trademark Office) trademark application may find their FBA inbound shipments blocked, even if they have a GS1-issued UPC. This change is also closely related to the recently discontinued commingling (inventory blending) policy and can be interpreted as Amazon's move to further enhance supply chain transparency and brand protection.

Therefore, accurately understanding and preparing for the GTIN and Brand Registry policies now is essential for your business continuity.

Key GTIN and Listing Rules

To successfully list products and utilize FBA on Amazon, here are the key GTIN and listing rules:

1. GS1 Barcode Use is Mandatory: For most product categories, Amazon requires the use of valid GTINs (UPC, EAN, ISBN, etc.) issued by GS1 (Global Standards 1). GS1 is a non-profit organization that manages barcode standards worldwide, and Amazon verifies validity by cross-referencing GTIN information with the GS1 global database. 2. FBA and Brand Registry: Not an Option, But a Requirement: As of now, sellers who intend to use manufacturer barcodes (UPC) for FBA inbound shipments must enroll in Brand Registry. This means that as a brand owner, your trademark must be registered with the USPTO. Without a registered trademark, you cannot use manufacturer barcodes for FBA, even if you have a GS1 barcode. 3. Exact Brand Name Match: The brand name you enter when listing a product must exactly match the brand name registered in the GS1 database. Even a single character mismatch can result in GTIN errors (e.g., 8541, 8542, 8572) and lead to listing rejection. 4. Utilizing GTIN Exemptions: Not all products require a GTIN. If your product falls under specific conditions, such as custom-made items (handmade), private label products, parts without barcodes, or bundled products consisting of multiple items, you may be able to apply for a GTIN Exemption.

Serious Consequences of Policy Violations

If you violate GTIN and listing guidelines, you could face the following serious consequences:

⚠️ Product Listing Rejection or Deletion: Using an invalid GTIN or violating policies can lead to your product listing being rejected outright or existing listings being deleted. ⚠️ FBA Inbound Rejection: With recent policy changes, attempting to send FBA inventory using manufacturer barcodes without Brand Registry can result in your shipment being rejected. ⚠️ Error Codes: During the product listing process, various error codes such as 5665, 8541, 8542, 8556, and 8572 may occur, halting your listing progress. ⚠️ Seller Account Suspension: Repeated or severe policy violations can lead to a full account suspension, resulting in lost sales and business disruption.

3 Action Plans for Amazon Sellers

Here are three actions Amazon sellers can take right now:

1. Verify and Pursue Brand Registry: If you plan to use manufacturer barcodes for FBA, prioritize registering your brand with Amazon Brand Registry by filing a USPTO trademark application. Trademark applications take time, so it's crucial to start early. 2. Directly Purchase or Validate GS1 Barcodes: For your private label products, you must purchase the necessary GTINs (UPC/EAN) directly from GS1 Korea (Korea Chamber of Commerce and Industry, Distribution & Logistics Promotion Agency). If you are already using barcodes, you should verify their validity by checking for a match between the brand name and GTIN in the GS1 database. 3. Review and Apply for GTIN Exemption: Check if your products qualify for a GTIN Exemption, such as custom-made items, handmade goods, private label products, parts without barcodes, or bundled products. If they qualify, you can apply for a GTIN Exemption in Seller Central to save on unnecessary barcode purchase costs (Menu path: Catalog → Add Products → Select "I'm adding a product not sold on Amazon" → Enter brand name → Check "This product does not have a Product ID").

Common Mistakes to Avoid

Purchasing Barcodes from Third-Party Resellers: Many sellers purchase barcodes cheaply from online sellers other than GS1. However, Amazon only recognizes barcodes directly issued by GS1. Barcodes purchased from third parties may fail validity checks and lead to listing rejection. Reusing Existing GTINs or Brand Name Mismatches: Reusing an already used GTIN for a different product, or if the brand name entered in your listing does not exactly match the brand name registered in the GS1 database, errors will occur. This can compromise the accuracy of the Amazon catalog and lead to duplicate listings, which is strictly prohibited.
