Start Small with a GS1 US GTIN

Choose the Choose the Global Trade Item Number® GS1 US GTIN® as a low-cost way of launching new products in online marketplaces, e-commerce, and retail channels. These product identifiers can be licensed one at a time and are a great way to begin building up seller reputation.

If you have only a few products that need barcodes, starting small with single GTINs might be the most cost-effective option for your company. GS1 US GTINs help empower small businesses that are looking to quickly list their products for sale.

Scale Up with a GS1 Company Prefix

For growing businesses with many products or a need to identify a location, it can be more convenient to license a GS1 Company Prefix. With a GS1 Company Prefix, you can assign multiple GTINs, U.P.C. barcodes, and other supply chain identifiers. You can use these identifiers for products and higher levels of packaging like a case or pallet.

Every GS1 US Global Trade Item Number (GTIN) and U.P.C. barcode identifies your company as the unique brand owner. Many organizations use this data to validate barcodes

 

For your convenience, you can create barcodes, and manage all your GS1 identifiers and product data via our tool, GS1 US Data Hub®. You also have access to live support from a professionally trained customer service team.
