Is Reverse Phone Lookup Legal in New Hampshire?
Yes. New Hampshire does not restrict the personal use of reverse phone lookup services. The state enacted a privacy law in 2024 that took effect January 1, 2025, giving residents rights comparable to neighboring Connecticut. The Fair Credit Reporting Act (FCRA) prohibits using lookup results for employment, tenant, or credit decisions everywhere in the US. New Hampshire's NH-DPA layers state rights on top of these federal protections.

The New Hampshire Privacy Act (NH-DPA, NH RSA § 507-H, enacted SB 255, 2024) took effect January 1, 2025, following the Virginia VCDPA template. Residents can opt out of personal data sales and targeted advertising, and have rights to access, correct, delete, and port their data within a 45-day window. On nonprofits: IRC 501(c)(3), 501(c)(4), 501(c)(6), and 501(c)(12) organizations are exempt, but other nonprofit sub-types (labor unions, lodge societies, etc.) are not automatically covered by that exemption (source: Wagenmaker & Oberly analysis).
