# Manage tags for a VPC Lattice service
<a name="service-tags"></a>

Tags help you to categorize your service in different ways, for example, by purpose, owner, or environment.

You can add multiple tags to each service. Tag keys must be unique for each service. If you add a tag with a key that is already associated with the service, it updates the value of that tag. You can use characters such as letters, spaces, numbers (in UTF-8), and the following special characters: \$1 - = . \$1 : / @. Do not use leading or trailing spaces. Tag values are case sensitive.

**To add or delete tags using the console**

1. Open the Amazon VPC console at [https://console.aws.amazon.com/vpc/](https://console.aws.amazon.com/vpc/).

1. In the navigation pane, under **VPC Lattice**, choose **Services**.

1. Select the name of the service to open its details page.

1. To add a tag, choose **Add tags** and enter the tag key and tag value. To add another tag, choose **Add new tag**. When you are finished adding tags, choose **Save changes**.
