New Hampshire - 14th US State With A Consumer Privacy Law


On March 6, 2024, New Hampshire Governor Chris Sununu signed SB 255, New Hampshire’s consumer privacy law, making the state the 14th US state to adopt a comprehensive privacy law.

Effective as of January 1, 2025, New Hampshire’s privacy law sets lower thresholds for applicability compared to other US states, offers a 60 day cure period for violations, which will be discretionary as of January 1, 2026, and provides no private action rights or detailed penalties, emphasizing the need for businesses to update privacy compliance strategies.

New Hampshire is living up to our motto as the Live Free or Die State by ensuring that Granite Staters have control over their personal information [...].This law provides transparency about what information is collected, why, and confidence that in the age of AI, steps are taken to protect that data.
