Good to know

UPC codes are typically 12 digits long and are most often used in the U.S. and Canada. They’re just one type of GTIN (Global Trade Item Number), with the 12-digit UPC-A format being the most common. If you’re selling internationally, you might also encounter other GTIN formats like EANs or ISBNs. No matter the format, making sure each product has a unique and valid identifier helps keep your catalog organized and improves data accuracy across retailers and platforms.

Frequently Asked Questions

What’s the difference between a UPC and a GTIN?
A UPC is a specific type of GTIN (Global Trade Item Number). GTIN is the broader term that includes several formats like UPC, EAN, and ISBN. A UPC typically has 12 digits and is commonly used in North America.
Can two different products have the same UPC?
No. Each product and variation (like size or color) should have its own unique UPC. Reusing the same code for multiple products can cause listing errors, inventory issues, or confusion across retailers.
Where do UPCs come from?
UPCs are issued by GS1, the global standards organization for product identification. Businesses can license UPCs directly through GS1 or sometimes buy them through authorized resellers, just make sure they’re valid and properly registered.
