What is a UPC?

• A UPC (Universal Product Code) is the barcode scanned at checkout.
• It tells the system what the product is and who made it.

How a UPC Is Built

• Most UPCs have 12 digits.
• The last digit is a check digit—used to catch barcode errors.
• It’s split into two parts so scanners can read it either way.

Two Main UPC Types You Might See

• UPC-A (12 digits) – The standard version used on most products.
• UPC-E (8 digits) – A shorter version used on small items (like gum or candy).

What to Watch For in XSite

If you’re seeing barcode issues:

• Some products may show up with 8 digits (UPC-E) and others with 12 digits (UPC-A).
• Use the search bar in XSite to find the item by UPC.
• If XSite shows an 11-digit UPC, that usually means the last digit is missing.

What to Do

• Check the physical product: Compare the barcode on the item to the one in XSite.
• Go to the item in XSite: On the item’s page, click “Inventory” to see if it’s been selling.
• If there are no sales and the UPC is wrong, you can either:
  • Fix the barcode to match the actual product.
  • Delete the bad UPC if it’s not being used.
