Brand, GTIN, and MPN (product identifiers)

Brand

Every product needs a brand. Pin Data Connect fills it in from your Settings. If you sell other companies' products, change it to the manufacturer's brand on those products.

GTIN (barcode number)

A GTIN is the number under a product's barcode: a UPC, EAN, or ISBN. Enter digits only. If a product you resell has one, add it: platforms match it to their product listings, which helps your products show up. GTIN is on Enhanced catalogs.

MPN

An MPN (manufacturer part number) identifies a product from its maker. If there's no GTIN, the brand plus MPN can identify it instead.

You make your own products?

Handmade, custom, print-on-demand, and art products usually have no GTIN, and that's fine. Leave GTIN and MPN blank. On Google and Bing Enhanced, set Identifier Exists to FALSE to tell them it's expected.
