Understanding your New Hampshire Department Health and Human Services data breach notification letter
If a New Hampshire Department Health and Human Services letter arrived in your mailbox, here is what it means, why you received it, and the free steps you can take right now.
Why you received this letter
The New Hampshire Department of Health and Human Services (DHHS) is a government agency responsible for providing essential public health and social services to state residents. As a public entity overseeing sensitive programs, the department collects and maintains vast amounts of highly confidential information, including personal identification, medical histories, and financial records necessary for benefit eligibility. In 2025, the department officially reported a data breach to the New Hampshire Attorney General, confirming that unauthorized parties may have accessed sensitive information stored within their systems. If you have received a formal data breach notification letter from the agency, it indicates that your personal information was potentially involved in this security incident. This notice is intended to inform you of the event and provide guidance on the steps you can take to protect your identity and monitor your accounts for suspicious activity.
What to do after the letter
Confirm the notice is genuine
A legitimate New Hampshire Department Health and Human Services notice references the specific incident reported to the New Hampshire Attorney General and describes which categories of your information were involved. Compare the letter against the public filing before acting on any links or phone numbers it contains.
Keep the letter — it is your proof of connection
The notification letter is the document that ties your personal information to this incident. Keep the original and photograph it. If you later request a case review, this letter is the strongest evidence that you were among the affected individuals.
Protect your accounts and credit
Depending on what was exposed, consider a free credit freeze with all three bureaus, new passwords for reused credentials, and monitoring of financial statements. These steps are free and do not require you to wait for anyone's permission.
