Recent activity
Puerto Rico : a finder must hand the item to the municipal authority immediately, not to a police station, and the municipality publishes a public notice. Three months after that notice, an unclaimed item, or its value, is awarded to the finder, and an owner who gets the item back owes the finder one tenth of its value (31 L.P.R.A. §7966). (Civil Code of Puerto Rico, art. 749 (31 L.P.R.A. §7965))

How ReportLost Works for You
You File Your Report
Tell us what you lost, where you were when it happened, and when. We capture all the details that matter so the right people get the right information.
We Route It Locally
Your report reaches the Guaynabo Police Department, municipal offices, relevant businesses, and lost and found services. No more guessing which desk to call or where to start.
We Monitor Continuously
Our system scans the web, local Facebook groups, Nextdoor, marketplaces, and community posts for 12 months. The moment a credible match appears, you get an alert. You don't have to refresh pages or ask around every day.
Where to Report in Guaynabo
Direct contacts for police, city services, airport lost and found, and animal welfare. ReportLost coordinates these for you.
Guaynabo Police Department
The municipal police maintain a lost property log. We identify which precinct covers your loss location and generate the exact details to include when you contact them. Most items held 30 days; ask about extended storage for high-value items.
City Hall & Municipal Services
The Autonomous Municipality of Guaynabo coordinates public lost and found inquiries through its main office. We can direct your case to the right municipal department and ensure your report is logged in their system.
Luis Muñoz Marín International Airport (SJU)
If your item was lost at the airport, the Lost and Found office on the Arrivals floor of Terminal B is your first stop. Open weekdays, 8 AM to 4 PM. We'll direct you to the exact terminal or security checkpoint desk that may be holding your item.
Lost & Found Pets
The Humane Society of Puerto Rico, located in Guaynabo, is the primary shelter for lost and found animals. They also work with PawBoost and local rescue networks to reunite pets with owners. If you've lost a pet, file a priority lost pet report for faster outreach to shelters and rescue groups.

The Sooner You Report, the Better
Items left in public spaces, on buses, or at businesses tend to move quickly. An early report lets us begin monitoring right away and gives the official channels a fresh trail. Once your report is in, the legwork shifts to our team and the local services we've contacted.
Report my lost item →Losing something in Guaynabo throws you into a fragmented search. The police have a lost property system. City Hall coordinates differently. The airport, if that's where it went, has its own office. Local Facebook groups buzz with found-item posts, but you'd have to check them daily for months. ReportLost collapses all that friction. One submission, and the right channels get notified on your behalf.
What sets us apart is the monitoring layer. After your report lands, our automated system keeps watch across the web, scanning for posts, listings, and announcements that match your lost item's description, location, and timeframe. You stay in the loop with alerts, but you're free from the exhausting work of searching manually every single day. Think of us as your ongoing presence in the search, even while you're busy with life.
Common Places Where Items Are Lost in Guaynabo
Local hotspots and public spaces. We'll help you search the right channels for each area.
Plaza San Patricio
A busy commercial hub where wallets, phones, and bags frequently go missing. Check with shop owners and mall security immediately; we'll ensure the police log is also flagged.
Downtown & José de Diego Street
The municipal center and main commercial corridor. Items lost here often end up at City Hall or the police precinct. We'll coordinate with both.
Public Transportation Routes
Buses serving Guaynabo and connecting to San Juan can be a black hole for lost belongings. We'll check with individual bus drivers and transit hubs, but speed matters here.
Residential & Neighborhood Areas
Items lost in neighborhoods often reappear on local Facebook community groups or Nextdoor. We monitor these channels continuously so you don't have to.
Luis Muñoz Marín International Airport
A high-traffic zone where luggage, electronics, and travel documents vanish. The airport's own lost and found holds items for a limited window; we ensure you contact them quickly.
Local Community Channels
Guaynabo residents share found items and lost-and-found posts on these platforms. ReportLost monitors them for you.
Reddit's Puerto Rico community, where locals post lost and found items and ask for help
Neighborhood and Guaynabo-specific groups where residents regularly post found items and alert neighbors
Geographically targeted app popular in Puerto Rico for neighborhood lost and found posts
The official city Facebook page, sometimes used for announcements about found property
Frequently Asked Questions
How long do the Guaynabo Police keep lost items in their custody?
The police department typically holds lost property for 30 days. For items of significant value or sentimental importance, ask the officer taking your report if extended storage is available. This is why early reporting is crucial; it buys time for the item to be claimed or processed.
What if I lost my item at Luis Muñoz Marín Airport?
Contact the Lost and Found office at (787) 253-5637, open Monday to Friday, 8 AM to 4 PM. Items are held on the Arrivals floor of Terminal B. You can also submit an online claim through their lost and found portal. Response time is typically 10 business days.
Are there transit buses serving Guaynabo, and do they have a lost and found?
Public buses operate throughout Guaynabo and connect to San Juan. Each bus operator may hold found items briefly, but there is no centralized lost and found for Puerto Rico's public transit. Contact the driver or the transit authority directly. We'll help you identify which route to reach out to based on where you lost your item.
How does ReportLost monitor Facebook groups and Nextdoor in Guaynabo?
Our system scans public posts on local Facebook community groups, the Municipio's official page, Nextdoor, and Reddit communities for keywords matching your lost item's description, location, and date. When a credible match is detected, you receive an instant alert so you can follow up.
What if I lost a pet in Guaynabo?
The Humane Society of Puerto Rico in Guaynabo is the primary shelter. File a lost pet report with them immediately and post on PawBoost, local Facebook pet groups, and Nextdoor. ReportLost offers a dedicated lost pet report service that amplifies your alert to shelters, rescue networks, and social channels simultaneously.
Is ReportLost affiliated with the Guaynabo Police or City Hall?
No, ReportLost is an independent service. We are not part of any government agency or police department, but we route your report to them and monitor public channels on your behalf. We complement official processes by adding continuous automated surveillance and alerting so you don't have to do the daily legwork yourself.
