# ID namespace target
<a name="create-id-namespace-target"></a>

The *ID namespace target* is the target of the data in an [ID mapping workflow](create-id-mapping-workflow.md). All sources resolve to the target.

Before you create an ID namespace target you must first create a matching workflow or have a subscription to a provider service (LiveRamp), depending on your use case. For more information, see [Match input data using a matching workflow](create-matching-workflow.md) and [Step 1: Subscribe to a provider service on AWS Data Exchange](prepare-third-party-input-data.md#subscribe-provider-service).

After you create an ID namespace target, you can use it along with an ID namespace source in an ID mapping workflow. For more information, see [Map input data using an ID mapping workflow](create-id-mapping-workflow.md).

There are two ways to create an ID namespace target in the AWS Entity Resolution console: the [rule-based method](create-id-namespace-target-rule-based.md) or the [provider services method](create-id-namespace-target-provider-services.md).
