# Error: Some of the information submitted contradicts information in the Amazon catalog - Amazon Marketplace Plus

You get an error like this in the product submission report (creation mode) or on Amazon Seller Central, under the "[Fix your products](https://doc.common-services.com/en/article/generating-the-report-amazon-marketplace-plus-ql3ave/#2-attention-possible-rejection-after-processing)" section:

## Cause of the error

This is a **matching error** with an existing Amazon product.

Amazon detects that the submitted EAN already exists...  
…but the **product data conflicts** with its database.

---

## Common causes

* Title, brand or manufacturer don’t match
* Different attributes (e.g. color: taupe vs grey)
* Another seller misused the EAN
* Same product has multiple EANs

---

## Possible solutions

### 1. Switch to "offer" mode (recommended)

* Do not send the product as a creation feed
* Send it as an **offer** (stock, price, etc.)
* Amazon will use the existing product listing

### 2. Force the ASIN (if known)

* Use the ASIN shown in the error message
* Add it in the product’s [Amazon tab](https://doc.common-services.com/en/article/product-sheet-extension-amazon-marketplace-plus-1rrc4dg/)

---

## Note

Before forcing an ASIN, make sure there are **no major differences** (e.g. wrong color or version).

If another seller used the wrong EAN, contact **Amazon support** to request mediation and prove your ownership.
