> Add, remove, and organize tags for your devices in the emnify Portal

Tags help you organize, filter, and search devices across the emnify Portal.
They can be applied individually or in bulk, and later updated or removed when no longer needed.
Using tags effectively allows you to quickly locate devices, group them by usage or policy, and maintain a clean, scalable workspace.

This guide shows you how to add, edit, and remove tags from your devices.

> **Tip**
>
> The [Tag devices section](/portal/connected-devices#tag-devices) of the **Connected Devices** overview provides more information on naming conventions, tag behavior, deletion logic, and where tags are available in the Portal.

## Add tags to a device

In [**Connected Devices**](https://portal.emnify.com/connected-devices), find a device where you want to add the new tag and click anywhere on the table row to open the device details.

Click **Add tag**.

In the search field, enter a tag name.

* Use only allowed characters (`A-Z`, `a-z`, `0-9`, `- _ . +`).
* Tag names must be at least 2 characters and cannot exceed 150 characters.
* If a tag name already exists, select it from the list instead of creating a duplicate.

Press the `Enter` key to create your new tag.

> **Note**
>
> Each device can have up to **30 tags**.

## Bulk add tags

In [**Connected Devices**](https://portal.emnify.com/connected-devices), search for the devices where you wish to add the tag and select the checkbox next to every relevant device.

A new menu at the top of the page provides bulk operations.
Select **More** and then **Add Tags**.

Select the tags you want to add from the list or create a new tag, then click **Add tags**.

## Edit tag details

You can change an existing tag's name or color.

> **Note**
>
> Tags belong to your Workspace, not to an individual user or device.
> Editing a tag's name or color changes the tag itself, so the update applies to every device that uses the tag and is visible to all users in your Workspace.

In [**Connected Devices**](https://portal.emnify.com/connected-devices), find a device with the tag you want to edit and click anywhere on the table row to open the device details.

Select the tag you want to edit.

Edit the field as follows:

* **Tag title**: Enter the new title and press the `Enter` key to confirm.
  See [naming conventions](/portal/connected-devices#naming-conventions) for requirements.
* **Color**: Select a different color.
  Changes are saved automatically and applied Workspace-wide.

## Remove tags from a device

In [**Connected Devices**](https://portal.emnify.com/connected-devices), find a device with the tag you want to remove and click anywhere on the table row to open the device details.

Click **X** next to the tag to remove it from this device.

## Bulk remove tags

In [**Connected Devices**](https://portal.emnify.com/connected-devices), search for the devices where you wish to remove the tag and select the checkbox next to every relevant device.

A new menu at the top of the page provides bulk operations.
Select **More** and then **Remove Tags**.

> **Info**
>
> This option only appears if at least one of the selected devices already has tags.

Select the tags you want to remove from the list, then click **Remove Tags**.
In the removal dialog:

* Only tags applied to the selected devices are listed.
* By default, no tags are selected—you must choose the tags you want to remove.

Click **Remove tags** to confirm.

## Delete tags

In [**Connected Devices**](https://portal.emnify.com/connected-devices), find a device with the tag you want to delete and click anywhere on the table row to open the device details.

Select the tag you want to delete.

Click **Delete tag**.

* If the tag isn't assigned to any device, it's deleted immediately (no confirmation required).
* If the tag is applied to devices, you must confirm the deletion before it is permanently removed.
