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.

You can use these identifiers for products and higher levels of packaging like a case or pallet.

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.
