**'gtin'/'ean' contains invalid GTIN/EAN values**

### What does this issue mean? <a href="#h_01jpa4za3gkad4p8dmktkepbf5" id="h_01jpa4za3gkad4p8dmktkepbf5"></a>

An EAN or GTIN code is valid only when it meets specific requirements. If not, it's considered invalid.

* **The level of the error is ‘Mandatory’:** The code is required and must be filled in correctly for all items. You can either exclude the items that contain an invalid code from your feed, or change and add the codes in your import file so that they become valid.
* **The level of the issue is ‘Recommended’:** Check the items that contain the error and change the code in your import file to a valid code. If the code is empty, you will not necessarily need to add it to your import file.
