New Jersey's data broker law officially went live this week, adding another active state-level privacy regime to the compliance map that adtech and martech operators must navigate. AdExchanger's coverage underscored that this law — which requires data brokers to register with the state and honor deletion requests — is not a future concern but an immediate operational reality. For companies that aggregate, license, or resell consumer data, the New Jersey law joins a growing patchwork of state regulations that increasingly resemble a de facto national framework, even in the absence of federal legislation.
The practical implications for adtech are significant: data brokers feeding audience segments into DSPs, DMPs, and clean rooms need to ensure their New Jersey data handling is compliant now. This week's news is a timely reminder that privacy compliance has moved from legal department to product and engineering priority across the industry.
