How to fix “Missing or incorrect barcode (GTIN)” on Wix

Why it happens on Wix

• The product has a manufacturer barcode that was never added to its Google listing.
• The value entered isn’t a real GTIN, so it fails Google’s check-digit test.
• You send products with the data feed URL, which doesn’t include a barcode field you can fill in.

How to fix it

1. Find the real barcode on the packaging or in your supplier’s product list. Never make one up.
2. With Wix’s Google & YouTube connection: open the product’s listing form, tick “This product has a GTIN, ISBN or UPC Code” and enter it.
3. If you use the data feed URL instead, add barcodes to Merchant Center separately, for example with a supplementary data source, or let Merchant Guard add them from a spreadsheet.
4. If the product genuinely has no barcode (your own brand or handmade), leave it empty and make sure your brand is filled in.
5. Rescan in Merchant Guard to confirm Google has accepted the barcodes.
