 - **Asset tag information**: Enter information about the asset tag of the device. For example, enter `Owned by Contoso Corp` or `Serial Number: {{serialnumber}}`.
 
   Device tokens can also be used to add device-specific information to these fields. For example, to show the serial number, enter `Serial Number: {{serialnumber}}` or `Device ID: {{DEVICEID}}`. On the lock screen, the text shows similar to `Serial Number 123456789ABC`. When entering variables, be sure to use curly brackets `{{ }}`. [App configuration tokens](../apps/app-configuration-policies-use-ios.md#tokens-used-in-the-property-list) includes a list of variables that can be used. You can also use `DEVICENAME` or any other device-specific value.

   > [!NOTE]
   > Variables aren't validated in the UI, and are case sensitive. As a result, you may see profiles saved with incorrect input. For example, if you enter `{{DeviceID}}` instead of `{{deviceid}}` or '{{DEVICEID}}', then the literal string is shown instead of the device's unique ID. Be sure to enter the correct information. All lowercase or all uppercase variables are supported, but not a mix.
