If you’ve ever left your phone in the backseat of an Uber, you’re far from alone. But if you’ve forgotten a 75-gallon fish tank, a package of live butterflies or two wedding gowns, you’re in much more exclusive company.
Uber has released its 10th annual Lost & Found Index, highlighting the most commonly forgotten—and most unusual—items left behind by riders over the past year while also looking back at a decade of misplaced belongings.
Phones remained the most frequently forgotten item, with more than 1 million reported lost over the past decade. Wallets, luggage, keys, headphones, clothing, passports, glasses, jewelry and laptops rounded out the top 10 most commonly forgotten items.
Among this year’s most bizarre forgotten belongings were dentures with two teeth, breast milk, human hair, an ankle monitor, a live fish, a mannequin, a dishwasher, a wizard wand, a police radio, a propane tank, a meat slicer and a 75-gallon fish tank.
Other unusual items included 20 pounds of duck sausage, a package of live butterflies, a child’s prosthetic eye, a coffee table, two chrome exhaust tips and a textured photo featuring a rhinestoned image of Jesus.
New York City once again earned the title of America’s most forgetful city, followed by Miami, Chicago, San Francisco, Los Angeles, Washington, D.C., Dallas, Boston, Atlanta and Newark, New Jersey.
According to Uber, July 17 was the most forgetful day of the year, while Sundays saw the highest number of lost-item reports. Riders were most likely to leave behind wallets on Mondays, headphones on Tuesdays, chargers on Wednesdays, bags on Thursdays, keys on Fridays, phones on Saturdays and glasses on Sundays.
The report also highlighted trends reflecting current pop culture and lifestyle habits. Labubu designer plush toys, Crocs, pickleball paddles, protein powder, sea moss, peptides and dental items such as dentures and gold grills all appeared frequently among forgotten belongings.
Uber’s review of the past decade also revealed a collection of memorable lost items, including a lobster in 2017, divorce papers in 2018, a salmon head in 2019, a lanyard reading “virginity rocks” in 2020, a large painting of Kate Middleton in 2021, 500 grams of caviar in 2022, a toy poodle in 2023, a fake butt in 2024, a taxidermied rabbit in 2025 and this year’s 75-gallon fish tank.
To help riders recover misplaced belongings more easily, Uber has introduced an enhanced lost-item experience in its app. In California, Texas, Illinois, Pennsylvania, Washington, D.C., Georgia, Minnesota and Massachusetts, riders can now report a missing item and, once a driver confirms it has been found, request an Uber trip for the item’s return. Uber said it plans to expand the feature nationwide by the end of the year.
Riders can also continue contacting drivers directly through the Uber app or seek assistance through Uber’s online help center if they no longer have access to their registered phone.
