Can I use the barcodes Wcart generates when selling through retailers or marketplaces?

The generated values are meant for your own use, such as shelf labels, stock checks and point of sale. Wcart builds them from your product ID, so they are not registered numbers issued to your brand.

If a retailer or marketplace asks for registered barcodes, use the ones you were issued:

1. Go to Plugins → Product Barcodes.
2. Enter the Product ID and type your registered code into Barcode value.
3. Choose the matching Symbology (usually EAN-13 or UPC-A) and click Save barcode.
