How do I fix "No brand, GTIN or MPN"?

Fill in the brand. For products you make yourself, use your store's name. A barcode (gtin) or manufacturer part number (mpn) also counts.

Why Meta rejects this

Meta needs at least one of the three to identify the product and match it in ads and shops.

Meta-specific note

Meta needs at least one of brand, gtin or mpn on every product. For handmade or custom goods with no barcode, the brand alone is enough.

Valid values / expected format

✓brand: the brand name, or your store's name for products you make
✓gtin: the barcode number from the packaging
✓mpn: the manufacturer's part number

►Technical detail

Meta uses these identifiers to tell products apart and to match them in ads and shops. A product without any of them may not upload. brand is the easiest to fill in, because every product has one: the manufacturer's, or your store's name for your own products.
