Amazon Error Code 5665

Message Displayed: “Amazon must approve your brand before you can use it to list products. Brands should be registered through Brand Registry, but if your brand is not eligible for Brand Registry, you can obtain an exception by contacting Seller Support and mentioning code 5665.”

This error is typically unrelated to the barcode itself, as barcodes do not trigger this specific error. Instead, it occurs because Amazon requires proof that you are the brand owner of the product you are attempting to list. To resolve the issue, you may need to provide one or more of the following:

  • Trademark registration: If your brand is trademarked, submit the registration details.
  • Evidence of brand association: Show that the brand name is valid and connected to your product.

Documentation Amazon May Request

  1. Product Images
    Images must clearly display the brand name permanently affixed to the product.
  2. Packaging Images
    If the product itself does not feature the brand name, provide images of the packaging where the brand name is prominently displayed.
  3. Brand Authorization Letter
    If you are an authorised seller for the brand, submit an authorisation letter from the brand owner.
  4. Invoices
    Supply invoices from a verified supplier showing the brand name and purchase details.

Barcode Considerations

The barcodes we supply are issued by the Uniform Code Council (UCC) and will display the first prefix holder when checked on GS1’s database. This can makes the listing process more complicated when using your GTIN for brand verification.

Since GS1’s site is not ideal for verifying your brand using reseller barcodes, we can provide a Letter of Affiliation, which Amazon may accept as part of the verification process.


Workaround: Using N/A or TBA in the Brand Name Field

If you’re unable to provide the requested documentation immediately, you can list your product using N/A or TBA as the brand name. Once the product is listed, you should have the ability to edit the brand name through your Seller Central account.
