Get authentic UPC barcodes for Amazon

The GS1 US Data Hub is a free online tool provided with your GS1 US GTIN or Company Prefix. It helps you create, manage, and share GTINs, store product details, and download UPC barcodes.

For businesses with a GS1 Company Prefix, you can use the tool to generate GTINs based on GS1 Standards, ensuring accuracy and easy sharing with retailers. It eliminates the need for spreadsheets and reduces errors in product data.

The Data Hub also supports creating other barcodes, like GS1-128 and ITF-14, for shipping needs. Additionally, you can access and print your GS1 certificate directly from the tool if requested by retailers or marketplaces.

GTINs are essential for product identification on Amazon, helping products appear in more search results, improving visibility, sales, and customer loyalty. Proper GTIN usage ensures consistency between a product's physical and digital presence, which fosters long-term collaboration with the marketplace.

Amazon requires GTINs in over 25 product categories, with specific guidelines in Seller Central for exemptions, bundles, and multi-packs. Each sellable unit needs its own GTIN, whether it's a single item, a bundle (e.g., hair accessories), or a multi-pack (e.g., four boxes of crackers).

Understanding Amazon’s rules is crucial, as certain items cannot be bundled or sold in multi-packs, and detailed listing information is required for such groupings.

If your Amazon listings are hijacked, it's important to report the issue to Amazon immediately. They will likely require proof of ownership, such as a GS1 Company Prefix or GTIN ownership certificate, to confirm the link between your company and the product. Amazon will verify the ownership by checking the GTINs in the GS1 database.

Hijacked listings typically occur in two ways: either by fraudulent sellers who steal a legitimate listing and profit from it without fulfilling orders, or by sellers who input random GTINs to bypass Amazon's GS1 standards. In both cases, providing your GTIN certificate will help Amazon validate your ownership and take appropriate action.

When listing products on Amazon, it's important to choose the right type of product identification (UPC, EAN, or GTIN) based on the number of digits in your product’s GTIN.

• If your GTIN has 12 digits, select UPC, as GTIN-12s are encoded in UPC barcodes.
• If your GTIN has 14 digits, it typically represents an outer case identifier (for example, a case of six drinks). Use this for case listings.
• Sellers in Europe will generally choose EAN, as their GTINs are usually 13 digits long.

The "Details do not match" error typically occurs when the brand or registered seller information on a product listing doesn’t match the details tied to the GTIN. For instance, if a GTIN licensed to "Ben’s Boots" is used to list "Nike shoes," Amazon will flag the error.

In such cases, the seller must provide proof of connection between the brand and the registered seller details. Amazon may request permission documentation, such as a letter of authorization or an invoice showing the purchased stock, to confirm legitimacy.

This process helps prevent counterfeit sales and listing hijacking.
