Quick Start Guide - GS1 US GTIN
Video from GS1 US. Watch on YouTube.
What you'll get
A short walkthrough from GS1 US of what its GTIN certificate is, how a Global Trade Item Number differs from a UPC, how to find your barcode in its Data Hub tool, and when to consider a company prefix instead. GS1 US sells the barcodes, so treat this as the official issuer's view and compare the prices on its site before you buy; each size or version of a product needs its own number.
Do this week
Count your products by size, color and other versions, since each needs its own barcode number, then use GS1's price page to choose between a single GTIN and a company prefix.
