Got a call from someone claiming to work for a New Hampshire government office? Check it at the source with New Hampshire State Telephone and Email Directory.
New Hampshire's Department of Administrative Services runs the State of New Hampshire Telephone/Email Directory for phone numbers of state agencies and staff.

If a caller says they work for a New Hampshire department, call the number the directory lists for it. Don't rely on caller ID.
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).
Under the New Hampshire Data Privacy Act (NHDPA), you can opt out of targeted advertising and the sale of your personal information. Visit each reverse lookup site and submit a deletion request through their privacy settings.
