Dropshipping changes who handles the stock, but the barcode question still comes up. Here’s how it applies.
When you need a GTIN
Marketplaces like Amazon often require a product identifier to list. As the seller of record, you provide it, not your supplier (unless they give you one).
Use a genuine, unique number per product to pass listing requirements.
Selling on your own store
On a self-hosted store you aren’t forced to use a GTIN, but adding one improves Google Shopping feeds and product structured data.
It also future-proofs you if you expand to marketplaces.
Avoiding duplicate issues
If multiple dropshippers list the same supplier product, reusing one barcode causes conflicts. Use your own unique numbers for your listings.
Keep a record of which number maps to which product.
