# Fixing the 'invalid EAN/GTIN' issue

### Issue <a href="#h_01jpa505qv1n8qz3by22z1vc6r" id="h_01jpa505qv1n8qz3by22z1vc6r"></a>

**'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.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://helpcenter.channable.com/list-advertise/list-on-channels/feeds-troubleshooting/fixing-the-invalid-ean-gtin-issue.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
