About the Unique Identifier Value for a Resource

In Configuration Manager, the Configuration Manager unique identifier property for a new resource class is optional. If you report inventory data for the resource, you must include this property. The Configuration Manager unique identifier value must be unique — it relates your resource discovery data to your inventory data (SMS_G_xxx). Typically, hardware resources use a GUID to uniquely identify individual resources.

The format of the Configuration Manager unique identifier value is as follows.

<ID Type>:<ID Value>

For example, Configuration Manager uses a GUID to identify Configuration Manager clients.

GUID:4976DCD4-CAAE-11D2-8E00-00104BCC3648

You can use any <ID Type> and <ID Value> values to identify a new resource. However, when discovering data for an existing resource type, you should follow the convention that is used by that resource type.
