I keep getting error code 8572. I gave seller support all the information they needed about my UPC code and I get the same response over and over again, I have provided the GS1 certificate so many times of proof that I'm associated with the UPC, and I bought it from the official GS1 UK site. It has been about 3 weeks since creating the first listing.

1. The details on the GS1 were correct. GS1 UK GTIN certificate provided few times.

2. The interval between the UPC purchase and the listing was more than 72 hours.

3. I have created and deleted the listing several times, and the same error 8572 keeps popping up.

Can you please help me? Case number 10526447422

My ltd company owns my trademark.

My ltd company owns 100 GS1 barcodes.

I create a barcode and make sure to put my trademarked brand, under the "brand" field, and have attempted with 3 different GTIN-13 barcodes so far, and always receive the error :

"8572: You are using UPCs, EANs, ISBNs, ASINs or JAN codes that do not match the products you are trying to list. If you believe that you have reached this message in error, please contact Selling Partner Support with the following information:

Product Name

Manufacturer name

Brand name

UPC, EAN, ISBN or JAN along with GS1 certificate

Non-brand owners: A copy of a letter/email from the manufacturer or brand stating that the UPC, EAN, ISBN or JAN that you are using to list this product is valid

Brand owner: Valid and current (not expired) GS1 certificate for the GTIN range(s) used by your listings"

I supplied all needed information to support as requested, and received this response :

"Hello from Amazon Selling Partner Support,

We understand that your are facing an issue with getting 8572 error while product listing.

We have investigated and found that the Brand and Manufacturer are not enrolled in GTIN Authority.

If a Brand/Manufacturer is not enrolled, then it shouldn't be blocked by GTIN error.

Kindly relist the product with the exact brand name (case sensitive). If your listing is still blocked with the 8572 error, provide us with the latest Submission ID so that we can further investigate the issue.

If you are manually listing the products and does not have a Submission ID, please provide a valid 8572 error screenshot with the Brand Name and GTIN clearly visible."

I have confirmed that my brand is indeed enrolled with GTIN, as I sent screenshots of my account, showing this.

Our limited company owns the barcodes, and our brand, and trademark. What part of the back end behind the scenes is not working here?

Any advice would be appreciated.
