New Hampshire has approximately 2 million active phone numbers. Mobile phones dominate with 1.5 million users, while traditional landlines are declining with just 120,000 connections statewide. Internet phone services account for about 366,000 numbers.
This indicates that tracing a New Hampshire phone number will likely lead to a cell phone. The continued decline of landlines means that newer phone numbers may be more challenging to trace compared to older landline numbers, which historically had more readily available public information.
