Lost something in Korea?
We'll help you find it.
Describe your item in any language or add a photo. We search items handed in to police and lost-and-found offices across Korea — and show you where it's held and who to call.
Searching with a photo — good to know
Many found items have no photo (only ~22% do). So we read your photo's type and color and search by text, and compare directly with candidates that do have a photo. Adding a description and place improves accuracy.
Please don't include names or phone numbers. Your text/photo is analyzed by Google Gemini for matching (photos are not stored), and reports are deleted automatically 30 days after the alert period ends. By searching you agree to the Privacy Policy and Terms.

Built to be trusted
Official data only
We only use found items published by Korea's National Police Agency (LOST112) and the Public Data Portal, refreshed every night.

No sign-up, and photos are never stored. Reports are deleted automatically after the alert period, and you can delete them anytime.
You always confirm
AI only suggests candidates. You check whether it's yours, and the holding office verifies your identity.
Frequently asked questions
Is it free?
Yes. It's free and needs no sign-up.
What items can I find?
Items handed in to police stations and lost-and-found offices across Korea and published on the National Police Agency's LOST112 portal and the Public Data Portal. We collect new items every night and search up to six months. Items still held at a station or shop and not yet registered may not appear.
How do I get my item back?
Call the holding office shown in the result to confirm they have it, then visit with your passport or ID. It helps to describe something only the owner would know (e.g., the cards in a wallet). LostKorea doesn't keep or deliver items.
What if it's not in the results yet?
Found items are registered over several days. Your search is saved as a report; leave an email and we'll compare it with new items every day during the alert period (30 days by default, up to 180) and email you when a strong candidate appears.
I don't speak Korean. Can I use it?
Yes. The site is in English, and you can search in any language. Match reasons and alert emails come in your language. If calling the office is hard, call 1330, the Korea Travel Helpline (24/7), for interpretation.
What does the score mean?
It's the AI's estimate (0–100) that the found item is yours. 80+ is a strong candidate, 50–79 is similar. Even a high score isn't certain, so please check yourself.
Is my personal data safe?
No sign-up, and photos are never stored. Reports are deleted automatically 30 days after the alert period ends, and you can delete them anytime under "My reports". See the Privacy Policy for details.
