A Household ID is a cross-device identifier that sticks with a household over time. Once Screen6 has identified a cluster of User IDs that belong to the same household, such cluster will get assigned a Household ID. Over time, the User IDs within the cluster may change; new ones come in, others disappear. However, the Household ID for this cluster will remain the same. The User IDs that get linked to a Household ID can come from a mix of any type: cookies, IDFA's, MAC addresses, Smart TV IDs, etc...
