Questions about reporting a loss in Portsmouth
How long does the Portsmouth Police Department hold lost items?
Items are typically held for 30 to 90 days. Check with the Police Department at (603) 427-1500 to confirm the status of your item and any deadlines for claiming it.
If I lost something on a COAST Bus, how do I claim it?
Call COAST at (603) 743-5777 (option 1) to describe what you lost and when. They check their collection depot and hold items. Have your route information and travel time ready.
What if I lost something in a downtown restaurant or shop?
Contact the business directly as soon as possible—most Portsmouth retailers and restaurants hold lost items behind the counter for several weeks. ReportLost helps identify the right business and ensures they have your details.
How long does ReportLost monitor for my lost item?
Our system searches and monitors relevant channels—Facebook groups, Reddit, Nextdoor, marketplace sites, and local business posts—for 12 months. You'll get an alert the moment we detect a credible match.
What makes ReportLost different from just posting on Facebook myself?
Posting once on Facebook is a start, but we go further: we notify police and relevant businesses directly, we monitor multiple channels continuously (you don't have to refresh Reddit and Facebook daily), and we cross-reference descriptions, locations, and dates to spot matches you might miss. You file one report and step back; we keep searching.
Is ReportLost.org an official Portsmouth city service?
No, ReportLost is an independent service. We're not affiliated with the Portsmouth Police Department, the City of Portsmouth, or COAST Bus. What we do is coordinate your report across these official channels and monitor community networks continuously on your behalf so you don't have to do it yourself.
