Quick Tip: Detail pages – Matching to an existing product?


Hello everyone!

Customers will first learn about your offers on a product detail page. Amazon has policies in place to ensure each product detail page covers a single unique item. This helps give customers a clear and consistent buying experience.

If the product you want to sell already exists on Amazon, you must match it to the existing product detail page.

To match the product you want to sell to an existing product listing follow these steps:

  • In Seller Central, select Catalogue, click Add a Product, and then search for the product you want to sell on Amazon. The results are more accurate if you search for a product identifier such as a UPC, EAN, JAN or ISBN.
  • If you locate the product you want to sell, do the following:
  1. Click Sell this product.
  2. Enter your offer details in the data fields. Required fields are marked with an asterisk.
  3. Click Save.

It generally takes 15 minutes for your listing to publish on Amazon, and then your offer is visible to customers through search and browse.

Our next Quick Tip coming Thursday will focus on adding a new product.

You might want to add to make sure people check the brand which isn’t always correct and can land you in a lot of trouble if someone has used the Barcode for their own private label…

Also make sure that someone hasn’t used the barcode to list a multiple quantity of items (ie 3 creme eggs instead of just 1)


Hello Jessica

Thank you for sharing this information.

I have already got a thread open on 8572 error code.

We manufacture our own products and have UK brand registered with UK Gov and also have brand registry on UK AMAZON.

I tried your method to list our products but when selecting “APPLY TO SELL” it takes me to another page to request approval from another brand seller of similar product which i don’t want to do.

We have been selling on AMAZON UK for over 12 years and have account with UK GS1 for our EAN numbers besides all this have issue with the error code.

Thank You


Hi @Dedez!

Thank you for posting about this as it is really important! It is something that everyone should be aware of and I should also try and remember it when posting!

Have a nice weekend,


Hi @Clear_Braided_PVC_Pi

This sounds like your EAN has been used on another product. I would recommend contacting Seller Support with the EAN you are using and also the ASIN of the product the system is matching to so that they can investigate in more detail for you.



Hello Jessica

Thank you very much for your message.

Can you please advise how do i check the verification of EAN if they are used on another product by someone else.

We have been registered with GS1 UK for more than 10 years, So don’t understand how can someone else have an excess to our EAN number.

Please advise how can i check if our new unused numbers have been used by some else.

Would apppreciate you reponse.

Kind Regards



Hi Aslam,

Thanks for your reply, apologies for the delay in getting back to you.

I generally check for EANs using the steps in my first post above but this can be time consuming if you have a lot of products to check. I know that some sellers find out if EANs link to a product when they upload their inventory with a file upload and receive the error report. In the error report there will be what is referred to as a "matching error. The error indicates that the EAN links to another product in the Amazon system and the ASIN of the item is provided.

I don’t have information as to how someone has obtained your EANs. You will have to check with GS1 on this. If you are having this issue with a large number of products I would suggest asking them if they can issue you with new EANs for your products.

I hope this is of help.


Hello Jessica

Thank you for your response.

I checked some of our unused EAN numbers are they do appear to have been used.

We don’t list products by feed upload, All products are listed manually and despite this for last 3 months we have been getting error code 8572.

Yesterday i contacted Amazon Support again with the same issue and awaiting to hear from them.

Kind Regards



Hello Jessica

Thank you very much for your support.

Finally after persistent pursuing Amazon Support the matter is solved and all is working well.

They have not said what was wrong but i am happy now can list products hopefully this stays all within requirements.

Kind Regards



Hi Aslam!

I’m glad to hear that everything is working for you now! And many thanks for coming back to let me know :slight_smile:

Have a lovely day!


Hi Jessica,

I plan to list a product that already exists but with different color variations. The existing product comes in two colors - pink and purple - whereas mine will have pink, green and blue. Is it still considered the same product? I can add green and blue as additional color variations but what about purple which I won’t have? Is it possible to remove this variation only from my listing or do I have to create a new product with “my” colors?

Any help is appreciated.



Is it exactly the same as the parent - including the brand ?


The product is identical, yes. It is currently sold by one other seller and not linked to a specific brand.


have you checked the EAN on the listing and the product in hand ?


Hi @Ventas_Paraiso_Natur!

Thanks for your questions.

If the products are identical to the existing products then you will be able to add your new colours to the existing variation.
In order for the system to link your new colours into the existing variation you will need to list one of the existing items (with zero quantity if you are not selling it) along with your new colours.
Customers will see your offers when they select the available colour/s you have listed.

I hope this helps but please let me know if you have further questions.
