Dear Amazon Support Team,

I hope this message finds you well. I am writing to seek your assistance regarding an issue I am facing with a UPC I purchased.

On December 20, 2024, I bought a brand-new UPC from GS1. However, when creating a product, I encountered a conflict with ASIN B09PYPF1VD. I was informed by Customer Service that this ASIN was uploaded in 2022 and is not associated with any product I have created.

My objective is to generate a completely new ASIN for my UPC and not to associate it with the existing ASIN B09PYPF1VD. I would like guidance on how to separate my UPC from this ASIN and generate a new one.

Before posting this request, I reached out to Seller Support multiple times. The first representative advised me to delete the currently associated ASIN from my inventory list and re-upload the information using a template. I followed this advice, but the template upload failed due to an 8541 error, indicating a conflict between the product I tried to upload and ASIN B09PYPF1VD.

I have confirmed that my UPCs are brand new and correctly purchased. Therefore, I would appreciate your assistance in resolving this ASIN conflict and facilitating the creation of a new ASIN for my UPC.

For reference, my Case ID is 16898341061, and the relevant inventory batch numbers are 245729020081 and 246045020082.

Thank you for your help, and I look forward to your guidance on how to proceed. @Seller_j9Bd91CW3ZVpr @Seller_l7Jtck9jxnEA0 @Seller_8hQgfj6OVZYse @Seller_guPeMXBrBxqyU

Hi All

I am creating a new listing. Have an UPC number from GS1 for the parent. They come in small, medium and large. When I am in the variation page it is asking for an external product ID for each one. Either UPC or ASIN. It is not accepting the parent UPC for all the variations. Do I need a new UPC for the 3 size variations?

Thanks

Hi all, rather new seller here. Trying to add a new products, a hoodie in varios sizes. When I click on the Variation, I choose size and it doesn't come up with the size options. Not sure what I am doing wrong, but wondering if anyone has an input on this. Usually, when i click that, the options underneath come up and I can choose size or color if I choose color etc, but there are not options. Anyone have an issue with this or have any suggestions?
