New Hampshire's Do Not Call laws are governed by N.H. Rev. Stat. § 359-E:1 through § 359-E:11. The state requires telemarketers using automatic telephone dialing systems to register with the AG's Consumer Protection Bureau at least 10 days before using the system. Registration fee: $20/year. Caller ID blocking is prohibited — must display accurate telemarketer phone number. Safe harbor: telemarketers can escape liability by demonstrating (clear and convincing evidence) they have written compliance procedures, trained personnel, use current DNC list (no more than 3 months old), and monitor/enforce compliance. Violations constitute unfair/deceptive acts under NH Consumer Protection Act (RSA 358-A). Private right of action: actual damages or $1,000 (treble damages for willful violations).
