## What is a Tag Code/XUID?

A Tag Code or 'XUID' is a unique 8 or 16 character code which defines that tag within the ixkio platform.&#x20;

This XUID is used in the tag URL which is encoded on the NFC tag to direct to the ixkio platform (or used via the API).&#x20;

For example, a Tag Code of\
\
`12456ax`\
\
would be encoded onto an NFC tag as

`https://t.ixkio.com/12456ax`

This will then identify the Tag Code within the platform.&#x20;

### Encoding multiple NFC Tags with one XUID

In many use cases, a single Tag Code would be encoded onto a single NFC Tag allowing for full control over each and every tag.&#x20;

However, you can also encode multiple NFC tags (or QR Codes) using the the same Tag Code. For example, one Tag Code can be encoded onto 100 different NFC tags. In this instance, all 100 NFC tags would be managed together.&#x20;

{% hint style="warning" %}
If you encode multiple tags with the same tag code link, then changing the Response URL on ixkio will change the destination of *all* the tags encoded with that Tag Code.&#x20;

To manage tags individually, you must put a unique XUID on each tag.&#x20;
{% endhint %}

Important notes for encoding multiple NFC tags with the same XUID :&#x20;

* Chip Counts will not work correctly if the same XUID is used across multiple tags
* Authentication NFC Tags ***must*** be encoded with unique XUID (or CUID/UID) codes

## Creating a Tag Code

*<mark style="color:orange;">Batch Screen > Batch Function Panel > Add</mark>*

Tag Codes are created at the Batch level. Tag Codes can be added in any quantity up to your current account limit. \
\
Enter the quantity of desired Tag Codes and set the Status (Active or Inactive).

If you have enabled Assignment, then you will also need to select the starting Assignment Status of the Tag Codes. &#x20;

Click 'Add Tags' to add your Tag Codes.

You can add additional Tag Codes to a Batch at any time.&#x20;

{% hint style="info" %}
If you want to add Tag Codes with your own CUID or tag UID, then create the Tag Codes first. Then download the codes (get [Encoding Data](/getting-started/organisation-structure/batches/batch-settings.md#encoding-data)), then upload using [Associate Data](/features/associate-data.md).&#x20;
{% endhint %}

## Moving Tag Codes

Instructions on moving tag codes, can now be found on a dedicated page.

{% content-ref url="/pages/sXJJxOUWl4aXTZKmcGzC" %}
[Moving Tag Codes](/getting-started/organisation-structure/tags/moving-tag-codes.md)
{% endcontent-ref %}

## Deleting a Tag Code

*<mark style="color:orange;">Tag Screen > Tag Detail Panel > Settings Tab</mark>*

Select 'Delete' from the 'Tag Status' dropdown and click 'Update'. You will be prompted to confirm the deletion.&#x20;

{% hint style="danger" %}
Deleting a Tag Code is permanent and the Tag Code cannot be recovered. Proceed with caution. &#x20;
{% endhint %}

Deleted Tag Codes are not re-used on your account or any other ixkio account.&#x20;
