How ReportLost Works in Los Alamos
You file the report
Tell us what you lost, where, and when. We collect the details that matter to put your report in front of the right offices.
We route it to the right places
Your report goes directly to the Los Alamos County Police Department, the Animal Shelter (if it's a pet), Atomic City Transit, Los Alamos Airport, and gets posted to local social channels where community members actively search.

For your entire search period, your report stays active and continues matching against new found item posts, community announcements, and social media activity. You'll get alerts if a credible match appears, so you don't have to check every day.
Where to Report Lost Items in Los Alamos
Each channel below plays a role. ReportLost routes to all of them at once, but here's what to know about each.
Los Alamos County Police Department
The Police Department runs the official Lost and Found for general items in Los Alamos. They hold found property and can answer questions about ongoing investigations or items turned in to the county. We generate all the details you'll need and file the report on your behalf so you don't have to wait on hold.
Los Alamos County Animal Shelter
If you've lost a cat or dog, Animal Control is your first local resource. The shelter maintains a registry of found and missing pets and works to reunite animals with their families. They're located on East Road and can be reached by phone during business hours. For a faster, ongoing search that covers social channels too, file a priority lost pet report.
Atomic City Transit
Lost something on a local bus or at the transit center? Atomic City Transit handles lost items left on vehicles and at stops. They keep found items for a period before disposal, so contacting them quickly improves your odds. We'll make sure your report reaches their office and stay on the lookout for your item in community transit channels.
Los Alamos Airport
If you left an item at the airport, the airport's Lost and Found is where travelers turn in items found on the grounds or in the terminal. They operate Monday through Friday during business hours. We'll ensure your report reaches their desk and stays active as new items are catalogued.
Los Alamos County Services
The Municipal Building at Central Avenue is the hub for county administration and general inquiries. If your lost item involves county services or you need guidance on where an item may have been turned in, this is where to start. We connect you directly to the right department.

The Sooner You Report, the Sooner the Search Begins
In Los Alamos, items are most often recovered in the first few days after being lost. Filing your report right away gives you the best shot at a quick reunion. Once we have your details, the legwork shifts to us and our network of local partners. You've done your part; now let the system work for you.
Report my lost item →Losing a wallet, ring, phone, or beloved pet in Los Alamos means coordinating calls across multiple offices: the police non-emergency line, Animal Control, the bus transit office, the airport, and half a dozen Facebook groups. Each has different hours, different databases, and different search windows. By the time you've made all the calls, hours have passed.
ReportLost simplifies this. One form, filed once, reaches all the right channels at Los Alamos County simultaneously. And unlike a single police report or a one-off post, your report stays active for up to 12 months, continuously cross-referencing new found items and community alerts with your description. You report, we handle the coordination, and you can focus on your day while the search continues behind the scenes.

Frequently Asked Questions
How long does the Los Alamos Police Department hold lost and found items?
The Police Department's Lost and Found holds items for a period before they may be disposed of. Items are more likely to be recovered if reported quickly. Once your report is filed with ReportLost, we keep searching and alerting for matches throughout your 6 or 12 month search period, even if the police initial hold expires.

Call the Animal Shelter immediately at 505-662-8179 to report your pet missing. They maintain a registry and work to reunite animals with their owners. In addition, filing a report with ReportLost ensures your pet's information is shared across local social channels and community groups dedicated to lost pets in Los Alamos and White Rock, with ongoing monitoring for sightings and found matches.

Is ReportLost.org official, or does it replace the police?
ReportLost.org is an independent service that works alongside official channels, not as a replacement. We file reports with the Los Alamos Police Department, Animal Shelter, transit authority, and other local services on your behalf, and we amplify your report across community channels. You're still working with the official systems; we just handle the coordination and keep your search active longer than any single office can.
