The Visitor ID Attribute is used to store a unique identifier, such as email address or customer ID, as a Visitor Attribute. This Attribute is treated as a secondary identifier for the purpose of visitor stitching.

Identifying your visitors is a critical step in leveraging the power of visitor stitching. In every customer interaction, across channels and devices, there is an opportunity to capture the identity of the visitor in the form of attributes such as "customer_email" or "customer_id". As these attributes are encountered across multiple visitor sessions, AudienceStream will stitch together visitor profiles that share a visitor ID value to build a more complete profile of the visitor.
Visitor stitching is not enabled by default. Contact your account manager about activating this feature.

The Visitor ID attributes used to identify your visitors should contain values that meet the following requirements:
The system will not accept a value that does not satisfy the length and non-repeating requirements (i.e. you do not have to check for these conditions in the configuration).
Third-party vendors that also track visitor activity are also likely to have a unique identifier for each user. These values can also be used as a Visitor ID attribute in AudienceStream. To ensure uniqueness across all third-party vendors it's a best practice to create a separate Visitor ID attribute for each vendor that will be providing an identifier. For example, if your visitors have accounts with Facebook and Twitter you would create corresponding Visitor ID attribute for each vendor e.g., "Facebook ID" and "Twitter ID".
Be sure to review the guide on visitor stitching to ensure you create the most accurate Visitor ID attribute possible.

To set the value of a Visitor ID, you must first add an enrichment.
Use the following steps to add an enrichment:
A rule condition provides additional control over when an enrichment occurs. You can use pre-defined rules from the system or create your own custom rules.
Adding a new Rule via the Enrichments dialog box automatically applies it to the Enrichment.
