Deterministic Identifiers

Deterministic identifiers are based on identifiable data, such as log-ins, registration information, and offline customer data shared between a user and a data collector, which allows for a certain determination that the data relates to a specific individual. Common examples include email addresses, phone numbers, physical addresses, and dates of birth. Deterministic matching utilises these verified identifiers to link distinct user profiles from different devices—such as a desktop or a smartphone—to a single physical person via a common identifier. By accurately recognising the same user across multiple touchpoints, marketers can gain a clearer view of the customer journey, properly attribute conversions, and make better decisions to optimise their budgets.
