Where to report in Mount Rainier

Mount Rainier Police Department
The police department's lost and found handles items reported in the city. They're located at 3249 Rhode Island Avenue and open Monday through Friday, 9 a.m. to noon and 1 p.m. to 5 p.m. When you report with us, we make sure they have your full details.
Mount Rainier City Hall
City Hall at 1 Municipal Place can direct you to the right department or help you understand local procedures. The general information line handles questions about city services Monday through Friday, 9 a.m. to noon and 1 p.m. to 5 p.m. We provide them with the information they need to assist.
Maryland Transit Administration (MTA)
If you lost your wallet, phone, or purse on a bus, MTA's lost and found holds items for 30 days. You can report directly to them, but we can point you to the right procedure and make sure your description is in the system.
Regional Airports
If you lost an item while traveling through BWI, Reagan National (DCA), or Dulles (IAD), each airport maintains its own lost and found. We help you report to the right facility and location within the terminal.
Lost Pets
If you've lost a cat or dog in Mount Rainier, Prince George's County Animal Services can help reunite you with your pet. They hold animals and cross-reference reports with local shelters like BARCS. For the fastest response and ongoing alerts, file a priority lost pet report with us.
