You just realized it. Your heart sinks. That sickening realization that your wallet, phone, or—God forbid—your passport is no longer in your pocket or bag happens to the best of us in the Fog City. It’s a uniquely San Francisco kind of panic. Maybe you left it on a Muni bus while staring out at the Painted Ladies, or perhaps it slipped out of your pocket during a particularly windy walk across the Golden Gate Bridge. You’re standing on a street corner, frantic, wondering if San Francisco lost and found systems actually work or if your belongings have simply ascended into the great tech-void in the sky.
Losing stuff here is complicated. This isn't a small town where you just call "the" police station. San Francisco is a patchwork of different agencies, private businesses, and transit hubs. Honestly, your luck depends entirely on where you were when the item vanished. If you lost it at a bar in the Mission, your strategy is totally different than if you left it in the back of a Waymo or on a BART train heading toward Oakland.
The Muni Maze: Tracking Down Items on Public Transit
SFMTA (Muni) is where most items end up. It’s a massive system. People leave everything from high-end MacBooks to literal bags of groceries on those buses and light rail vehicles. If you left something on a Muni vehicle, do not call 311 immediately expecting an answer. They won't have it.

The way it works is actually pretty old-school. Drivers turn in found items at the end of their shifts at their specific divisions. This means it can take up to 48 hours for an item to even be processed. You have to go to the Muni Lost and Found office, which is located at 11 Arlington Street, near the Van Ness station. They are generally open Monday through Friday. It’s a basement-level vibe. Very bureaucratic. You’ll need to describe your item in excruciating detail because they get hundreds of black iPhones and generic keys every single week.
BART is a whole different beast. Because BART traverses multiple counties, their lost and found is centralized at the 12th St. Oakland City Center station. If you lost your bag on a train heading into the city, it might actually be sitting across the bay. They have an online reporting form which is surprisingly decent, but walking in is always more effective if you're desperate.
Ride-Shares and the Digital Paper Trail
Uber and Lyft have basically automated their lost and found processes. You go into the app, find your ride history, and tap "I lost an item." They then act as a middleman to connect you with the driver. But here is the thing: drivers are often miles away by the time you realize your phone is gone. They aren't required to drive back to you for free. Usually, there’s a nominal fee (around $20) that goes to the driver to compensate them for the trip to return your stuff. Be nice to them. They're doing you a massive favor by not just dropping it off at a police station which could be hours out of their way.
Waymo is the new player in the San Francisco lost and found scene. Since there’s no driver to check the backseat, the next passenger might find your stuff, or a remote technician might spot it on the internal cameras. If you leave something in a robotaxi, use the app support immediately. They can actually lock the vehicle or send it to a depot to secure your property.
The San Francisco Police Department’s Role
Most people think the first call should be to the SFPD. Unless you’re reporting a theft for insurance purposes, the police are rarely the best place to find a lost item. They don't have a giant warehouse of lost umbrellas and scarves. However, if you lost something truly valuable—like a wedding ring or a high-end camera—and a Good Samaritan found it, they might drop it off at one of the district stations like Central (North Beach) or Southern (SoMa).
Keep in mind that if your item was stolen rather than lost, the SFPD "Lost and Found" isn't the department you need. You'll be filing a police report online. If you're tracking a stolen phone via "Find My," the police generally will not go knocking on doors to get it back for you due to liability and safety protocols. They need a warrant for that, and for a single iPhone, that's almost never going to happen.
Specific Venues: Museums, Parks, and Stadiums
- SFO Airport: If you lost something at the airport, it depends on where it happened. At security? That’s TSA. At the gate? That’s the airline. In the terminal hallway? That’s the SFO Lost and Found office located in Terminal 1. They use a system called Hallway, which is actually quite efficient for tracking inventory.
- Oracle Park / Chase Center: These venues have their own internal security teams. If you dropped your wallet during a Giants game, call the guest services office the next morning. They are remarkably good at clearing out the stands and cataloging leftovers.
- Golden Gate Park: This is tough. It’s 1,000+ acres. If you lost something near the Academy of Sciences or the de Young, check with their specific front desks. If you lost it on a random trail, check the "Nextdoor" app or local San Francisco subreddits. Locals are surprisingly active in trying to reunite people with their dogs, keys, and wallets.
Why the "Human Factor" Still Matters
San Francisco gets a lot of bad press regarding crime, but there is still a very strong "pay it forward" culture here. Many people who find a lost wallet will look for a business card or a LinkedIn profile to message the owner directly rather than handing it to an official "Lost and Found" where it might get stuck in a drawer for months.

Check your "Filtered Requests" or "Message Requests" on Facebook and Instagram. I've seen dozens of cases where someone found a lost ID and tried to DM the person, but the notification got buried. If your phone is lost, put it in "Lost Mode" immediately with a callback number displayed on the screen. It sounds simple, but it’s the fastest way to get your device back.
Practical Steps to Take Right Now
If you are currently looking for something, stop pacing and do these things in this exact order.
First, call the last place you remember having it. Don't just show up. If it's a restaurant or a bar, they usually have a "lost box" behind the bar.
Second, if it was on transit, fill out the online forms for Muni or BART immediately. This creates a time-stamped record. For Muni, the number is 415-701-2311, but the physical office at 11 Arlington is your best bet for a real human interaction.
Third, check Craigslist "Lost and Found" and the "San Francisco" subreddit. People still post there. Use keywords like "Found keys Mission District" or "Lost backpack Sunset."
Fourth, if your credit cards were in a lost wallet, don't necessarily cancel them in the first ten minutes if you think you just left it at a friend's house. Use the "Freeze Card" feature in your banking app instead. This gives you a 24-hour window to find it without the hassle of changing all your autopay settings.
Fifth, if you are a visitor and lost your passport, you must contact your local consulate immediately. San Francisco is home to dozens of consulates (the Italian, Chinese, and Mexican consulates are all very busy hubs). You will need a police report number for an emergency travel document, so file that online report with the SFPD first.

The reality of San Francisco lost and found is that it requires persistence. Things often turn up days later after a cleaning crew finishes their shift or a bus returns to the depot. Don't give up after the first hour. Keep calling, keep checking the apps, and keep an eye on your social media inboxes. More often than not, your stuff is sitting in a plastic bin waiting for someone to claim it.
