# Tags

Tags are key and value labels on a bucket, such as `Environment: Production` or `Project: Backup`. They help you sort and find buckets. You can add tags when you [create a bucket](/buckets/create-a-bucket) or at any time later.

## Add or change tags

#### Open Manage Tags

In the Zata console, open **Buckets** and select the tag icon (**Manage Tags**) in the bucket's row. The **Manage Bucket Tags** window lists the current tags.

#### Edit the tags

Select **Edit Tags**. Then:

* change a value in its **Value** field,
* select **×** to remove a tag,
* select **Add New Tag** for a new key and value.

#### Save

Select **Save Changes**.

You can do the same from [Bucket settings](/buckets/bucket-settings): open **Bucket Tags** and select **Edit tags**.

## Tag rules

| Rule               | Limit                                                                                  |
| ------------------ | -------------------------------------------------------------------------------------- |
| Tags per bucket    | Up to 10                                                                               |
| Key                | 1 to 56 characters. Must be unique in the bucket. Cannot start with `aws:` or `ceph:`. |
| Value              | Up to 56 characters. A row without a value is not saved.                               |
| Allowed characters | Letters, numbers, spaces and `+ - = . _ : / @`                                         |

You cannot rename the key of an existing tag. Remove the tag and add a new one with the new key.
