What happens when you scan a barcode to add an item?
When you scan a product barcode using Ply Barcode Lookup and select "Add to Catalog and Inventory," Ply creates the new material and saves the scanned code as a barcode, not as a UPC.
This means:
✅ The material gets created successfully
✅ The scanned code is saved to the item, as a barcode
✅ Next time you scan that same code, Ply will recognize and pull up that material
❌ The code will not appear in the UPC field under Manage UPC in the item details
What's the difference between a Barcode and a UPC in Ply?
| Barcode | UPC |
Used for | Scanning & identifying items in Ply | Supplier-specific product codes |
Set automatically on scan | ✅ Yes | ❌ No |
Linked to a supplier | ❌ No | ✅ Yes (one per supplier) |
Used for RFQ/PO matching | ❌ No | ✅ Yes |
In short, a UPC is a supplier-linked code used for purchasing workflows, while a barcode is used for scanning and identifying items within Ply.
What if Ply can't find the barcode?
In some cases, after scanning, you may see this message: "We couldn't find any matching materials for this barcode. You can try searching again or add it as a custom item."
This means the scanned barcode doesn't match any existing material in Ply's database. In this case, you add it as a custom item; tap "Add custom item" and fill in the details manually. You can also check "Add to Catalog and Inventory" before tapping the button to save it directly to your catalog
💡 Note: Even when adding a custom item this way, the scanned barcode will be saved to the material as a barcode, not as a UPC. See below for how to add a UPC manually if needed.
Where to find, view, or replace the barcode on a material
🚀 Option 1: Scan + Assign

✏️ Option 2: Edit From the Location
Go to the location where the item lives
Find the item and click the three dots (⋯) next to it

Enter your barcode in the field and hit "Add code"
Want to remove the current one? Just click the "X"
How to manually add a UPC to a material from your mobile app:
If you also need the code to appear as a UPC (for example, for supplier matching in RFQs), you can add it manually:
Go to Catalog and open the material
Click on the "Information" tab.
Scroll down to Variations and click Manage UPC
Click + Add Supplier UPC
Select the supplier and enter the UPC code
Click Save ✅
