An Introduction to UPCs and GS1

As companies grow, being listed on large retail chain store shelves and ecommerce platforms is the goal for many. The retailer industry in Canada and beyond share the same system of scanning product bar codes at the till and tracking UPCs. When setting up a new product, a retailer links the barcode and UPC to their own internal product codes, pricing and inventory control systems.


How is the barcode generated?

First a brand owner needs to purchase a Universal Product Code (UPC) for each of their products, this number is then used to create the bar code pattern.


This example is of a barcode and the corresponding UPC numbers:

How does a brand owner get a UPC?

This is where the company GS1 Canada comes in. There are different places to purchase a UPC however, GS1 is the globally recognized controller of UPCs. If you purchase a UPC from a different source make sure they are an approved GS1 UPC providor, or you could find out down the road that you have a UPC that is already assigned to a different product.


GS1 and many retailers use the term GTIN (Global Trade Item Number) for the product code.


The GTIN can be different lengths but has a common pattern. The first digits belong to the company/brand owner IF they purchase their own prefix (this is not required for small companies who only need a few UPCs.) The next digits are specific to the item.

The final digit is a "check digit" for the purposes of quality control.

Does the barcode need to look a certain way?

Yes, GS1 Canada has published guidance on their website to help you understand the format requirements of the barcode and UPC.


What else does GS1 do?
