What circumstances might prevent a notification from being delivered to me?

- If your contact information has changed and you have not registered your new information.

- If you have only cordless phones in your residence, the power is out and you did not register an alternate phone number.

- If your line is busy for an extended time and your calls do not forward to voicemail or an answering machine.

- If you have a privacy manager on your main phone and you did not register an alternate phone number.


The City of Nashua and/or the State of New Hampshire will receive a report of undelivered calls and can instruct the NH Alerts system to begin another round of calls to busy numbers. It is best to have an alternate phone number in the calling database for these situations.
