2. Create Your Product or Location Identification

You’ve licensed your prefix (if not, click here). Now what can you do with it?

If you need to identify products for retail point-of-sale or at all package levels (inner packs, cases, and pallets), or if you need to identify medical devices for FDA UDI, select the Products (GTIN) tab below.

If you need to identify functional groups, like a department within an organization, or physical sites that ship, receive, process, or hold inventories, select the Locations (GLN) tab below.

To Identify Products, You’ll Need a GTIN
A GTIN® (Global Trade Item Number®) is the number you see underneath the U.P.C. barcode symbol—and it’s the same number that’s encoded in the lines and spaces above that the scanner reads. Used in both the physical and digital worlds, GTINs uniquely identify products at all item and package levels. In the physical world, GTINs are used in barcodes scanned at retail point-of-sale and on inner packs, cases, and pallets of products scanned in a distribution or warehouse environment. They are used to identify products sold online as well. They are commonly used on purchase orders and in delivery and payment documents. They can be encoded into various types of GS1 barcodes and Electronic Product Codes (EPCs), which are programmed into Radio Frequency Identification (RFID) tags. Also, they can be used in the Global Data Synchronization Network™ (GDSN®) through data pools and catalogs.

You will assign each unique trade item a separate, unique GTIN. The rules for assigning GTINs ensure that every variation of an item is assigned a number that is globally unique. You create a GTIN by combining your licensed U.P.C. Company Prefix number* with a unique product number that you assign, plus a check digit that ensures the GTIN is created correctly. A GTIN, along with a U.P.C. barcode, can be used anywhere in the world.

*Tip: Use your U.P.C. Company Prefix to create GTINs for U.P.C. barcodes. Use the GS1 Company Prefix to create all other identifiers and barcodes. You can find both numbers on your GS1 Company Prefix Certificate.

To Identify a Location, You’ll Need a GLN
The Global Location Number (GLN) is used to identify the locations of parties involved in business transactions. These can be functional groups within a company or real, physical “places” that might ship, receive, process, or hold inventories, like:

  • Legal Entities: Whole companies, subsidiaries, or divisions within a company, health system corporations, etc.
  • Functional Entities: Specific departments within a legal entity, such as accounting departments, purchasing departments, hospital pharmacies, etc.
  • Physical Locations: Manufacturing facilities, distribution centers, warehouses, dock doors, hospital wings, bin locations, retail stores, etc.

GLNs are commonly used in business transactions such as purchase orders, advance ship notices, and invoices. They are also used within barcodes on logistics labels and on electronic commerce systems such as Data Synchronization and Electronic Data Interchange (EDI).

The benefit of using GLNs is to enable standardized location identification that is shared across trading partners. They eliminate confusing variations in location names, eliminate the need to develop and translate different proprietary identification systems, and help ensure that the right product is delivered to the right place.

You create a GLN by combining your licensed GS1 Company Prefix number with a unique location reference number that you assign, plus a check digit that ensures the GLN is created correctly. A GLN is always 13 digits long, so the number of locations you can identify depends on the length of your GS1 Company Prefix.
