Assign Unique Product Numbers

Immediately after licensing a UPC company prefix or single GTINs, you can assign unique product numbers to each of your items on the GTIN.cloud management portal. GTIN.cloud acts as the sole source to manage your GTINs, enter corresponding product data, create your digital .eps barcodes, and upload your current licensing certificates. By default, your assigned GS1 consultant will automatically check all of your entered data and provide any assistance needed to ensure accuracy.

You need a unique product number for each variety of items you want to sell. For example, let’s say you’re selling t-shirts in two different styles – yellow and blue. Your blue small, medium, and large t-shirts would each have their own unique product numbers, while your yellow small, medium, and large t-shirts would also have their own different unique product numbers.

Product Style	Product Number	Full UPC (GTIN-12) Number
Blue Shirt – Small	00001	01234500001-0
Blue Shirt – Medium	00002	01234500002-7
Blue Shirt – Large	00003	01234500003-4
Orange Shirt – Small	00004	01234500004-1
Orange Shirt – Medium	00005	01234500005-8
Orange Shirt – Large	00006	01234500006-5
