Product Identifiers

What We'll Cover

Product identifiers are short codes used by both people and automated systems to quickly identify products. Shoppers use them when searching for products, and merchants use them for accounting, inventory, and listing products on other channels/marketplaces (like eBay and Amazon).


Adding Product Identifiers

The Product Identifiers section is under the Other Details tab when adding or editing a product.

  • Global Trade Item Number (GTIN) — An identifier for trade items that is incorporated into several product identifying standards like ISBN, UPC, and EAN.
  • Manufacturer Part Number (MPN) — MPN is a series of letters or numbers assigned to product by its manufacturer. There is no MPN standard so its format can vary between different manufacturers/companies.
  • Brand — You can add a new brand, or select from any brands you've created in the Product Brands area.
  • UPC/EAN — UPC-A is a 12-digit GTIN barcode standard dominant in North America, and UPC-E is a 6-digit code for smaller items. EAN is widely used outside of North America.

I don't know my product's identifiers. How/where do I find them?

MPN and UPC/EAN are typically assigned by a product's manufacturer. You may need to contact them or your supplier/distributor. If you are the manufacturer, there are several online services available to register UPC/EANs for your products.
