Where to report a lost item in Princeton
Direct contacts and what to expect at each office
Princeton Police Department
The Police Department maintains a lost and found for items turned in by the community. You can file a report for items lost in public spaces or turned in. We generate the exact information to include so your report is complete.
Princeton City Hall
City Hall can help direct you to the right city office depending on where you lost your item. If it was found at a city facility or public area, City Hall can advise you on next steps and which department to contact. We point you to the right desk.
Princeton Municipal Airport
If you lost an item at Princeton Municipal Airport or on a flight, contact the airport or your airline's lost and found. For flights arriving or departing through Minneapolis-St. Paul International Airport (MSP), MSP's Lost and Found office handles items left on planes, in terminals, or at gates.
Lost or found pet
Contact the Robert Lewis Memorial Animal Shelter or Tri-County Humane Society right away if you've lost a pet or found a stray. They can scan for microchips, connect you with local pet alerts, and check if anyone has reported a matching animal. You can also file a priority lost pet report with us, which reaches animal services and pet networks simultaneously.
⚠️ Spotted incorrect or outdated information? Let us know so we can review it.
Found something or a lead?
Once your report is active with us, come back and update it if you get information. The sooner details are shared with all the right offices, the better your chances. And if you find someone else's lost item, the networks we connect with can help reunite it with the owner.
Report my lost item →Losing something in Princeton means checking multiple places: the Police Department, City Hall, Facebook groups, local shelters if it's a pet, and maybe the airport if you were traveling through. Different offices, different phone numbers, no single place that knows about all of them. ReportLost simplifies this. One report, and we notify the right channels on your behalf.
The real advantage is what happens after you file. While you go about your life, your report stays active and continues to match your lost item against new posts and announcements across Princeton's community networks. If someone finds your wallet, ring, or pet and posts it anywhere, you'll get notified. No need to refresh Facebook groups every day or call back the police to check if anything new came in.

Frequently asked questions
How long does the Police Department keep lost items?
The Princeton Police Department retains found items for a set period before disposing of or donating unclaimed property. It's best to report your loss and contact them within a few days. When you file with ReportLost, we help you get the details to the Police Department immediately so your item is flagged in their system.
Can I report a lost pet even if I think it's been a while?
Yes. Pets can be missing for weeks and still be found. Contact the Robert Lewis Memorial Animal Shelter or Tri-County Humane Society to file a report, and post in local lost pet Facebook groups. With ReportLost, we route your lost pet alert to animal services and community networks right away, and keep it active so you're notified if a match appears.
What if I lost something on a bus?
If I lost my wallet at the airport, who should I contact?
First, contact your airline if it was on a flight. For items lost in the airport itself, contact the airport's lost and found. If you flew through Minneapolis-St. Paul International (MSP), call their Lost and Found office at 612-726-5141. ReportLost can help you figure out which office is most likely to have your item based on where you lost it.
Do I need to call Princeton Police directly, or does ReportLost do that?
ReportLost files your report with the Police Department and other relevant offices on your behalf, so they're notified right away. You can also call them directly at 763-389-4879 (day) or 1-888-860-8250 (night/non-emergency) if you want to follow up. Having both channels working increases your chances.
Is ReportLost.org official, or does it replace the police?
ReportLost is an independent service, not affiliated with the Police Department or City of Princeton. We work alongside official channels, not instead of them. Our role is to connect you with the right offices and keep your report active across community networks so you don't have to do all the legwork yourself. The Police Department and animal services remain your primary official contacts.
