Error: Products need GTIN or MPN or brand

Updated on May 30, 2024

Full error name: “Facebook: Products need one of the following universal identifiers to run in ads: GTIN, MPN, Brand Name


The reason why you are running into this error is because your products do not have at least one of these identifiers:

  • Global Trade Identification Number (GTIN).
  • Manufacturer Part Number (MPN).
  • Brand name.


In order to submit products to Facebook Catalog, you need to add one of the following:

  1. Brand Name. You can add this in the Brand field in Nembol.
  2. Unique Manufacturer Part Number (MPN). You can add this in the Barcode field in Nembol. 
  3. Global Trade Identification Number (GTIN) of the item (i.e. UPC, EAN, JAN, or ISBN). You can add this in the Barcode field in Nembol.
As for the MPN, we noticed that you can actually use any combination of numbers you want.

You only need to enter one of these, not all of them. Character limit: 100.
