Error 5461 - Amazon support not helping at all

Dear colleagues,

We manufacture a few products ourselves. We registered with GS1 and got all of our products verified by them. Then we started to try to list items on Amazon, that's when the problems started.

Firstly, our brand wasn't registered, we received an error 5665. Amazon support resolved this issue, our brand was registered and we finally received authorization to create new ASINs. I did create some manually - everything was working smoothly. But then life got in the way and I had to delay listing all of our products by 2 weeks.

When I finally got around to listing these products, I switched our account to the Professional plan, so that I can upload the products in a batch. Unfortunately, now I keep getting the error 5461. Seller support has been extremely unhelpful, they kept rejecting our requests to create new ASINs, and they claim that they cannot provide a reason why. I submitted all documents and pictures. Our facilities are visible, our product is correctly branded, our packaging and label information is up to date, we have a valid GS1 certificate and GTINs for all of the products. If need be, I can change the packaging or any other issue, it's not a problem, but Amazon support doesn't even list the reason.

We genuinely want to start selling on Amazon, it's a big platform. Our product is not cheap - Amazon could make money off of commissions. This practice is not only anti-competitive, but it also hurts Amazon's bottom line. Unfortunately, it's too big to care about a measly business. Shame.

I hope someone can help me or share any advice they may have.

Thank you!

Best regards
